The Lacote Décacorde and Heptacorde:
Multi-string Guitars, Extended Range Guitars, Bass Guitars or Harp Guitars?

by Gregg Miner
Fully revised February 2025


Introduction

It was with great sadness that I learned of the death of guitar expert Bruno Marlat in December 2019. Though he did not contribute directly to this article, his work is quoted generously throughout. After his death, his wife Catherine finished and published their monograph on Lacote, which is essential reading before or after reading my own article. I will not be duplicating their book material here, only drawing from it.

Conversely, my own article serves as a thorough Appendix on Lacote's non-six-string guitars, along with similar instruments by others and the modified instruments of Napoléon Coste. Please consider this page an permanently archived "work-in-progress," with plenty of discussion and speculation - one in which I rely on input from many different sources, all better informed and experienced than I (though often, sources who may offer very different opinions). These sources include scholars of every stripe, along with luthiers, dealers and collectors.


Historians, Collectors, Luthiers and Players of "classical" and "early romantic" guitar may be nonplussed by my title above. Lacote, the renowned Parisian luthier certainly never made "harp guitars," did he?  

Well, it's all a matter of semantics and perspective (actually, the answer to the title is "All of the Above"1).  Those familiar with my Harp Guitar Organology will recall that the "harp-guitar" term wasn't applied to instruments with floating sub-bass strings until the 1890s in America.  In Lacote's time, multi-course (multi-string) or extended range guitars were most often simply called "X-string guitars" ("X" being either 7, 8, 9 or 10).  In contrast, Lacote's instruments were specifically named the Heptacorde and Décacorde.2   Regardless, none of these multi-string guitars were ever "classified" for purposes of organology as we do today.  While Early Romantic Guitar historians may refer to the Lacote floating dropped-D string instruments below as "7-string guitars" (when not using the specific historical French name "heptacorde"), the term allows for no distinction between this simplest of recently-classified harp guitars and other standard, fully-fretted-across-the-neck 7-string guitars - ergo my choice (and strong suggestion) on also referring to these instruments today as 7-string or 10-string harp guitars (particularly of course in the context of this web site).3

While the majority of Lacote instruments are 6-string guitars, a significant number of these extended range versions were made.  Unfortunately for researchers, there are many instruments that were later modified into having seven strings or more.  Other "original" instruments shown below may be seen as suspect or at least unproven by one researcher or another (based on the responses I have received from various experts).


Pierre René Lacote

Widely considered one of the finest French luthiers, if not the 19th Century's most important French guitar maker, there was little biographical material about Pierre René Lacote until the Marlat book.4  By the age of twenty, he was working as a silver-smith for a merchant. Conscripted into the army, he was declared unfit and discharged the next year. It would be a dozen years since the 1805 military census and the first evidence of his lutherie in Paris. The Marlats postulate that Lacote may have entered luthier via first doing silver-smithing for lyre guitar for makers such as Lejeune, Ory or Pons. He would subsequently apprentice "under Pons." Of the many males in the extended Pons family, the Marlats deduced that it was Antoine who Lacote would apprentice with, not Joseph as has previously been reported. The first ten years of Lacote's career, addresses and and such are discussed in the Marlat book, and don't relate specifically to my topic.

I'll include this simple overview from from my original article: While credited for many innovations to the guitar, most of these can be considered "improvements" to previous inventions, such as new bracing, second soundboards, enharmonic frets and improved friction tuners. His one true innovation was his sophisticated encapsulated machine tuners. He worked closely with the best guitarists, including Sor, Carulli, Aguado and Coste, to create optimum instruments to meet their requests. He received awards for his guitars in 1839 and 1844 in the Great National Exhibitions (each time for his heptacorde).

Lacote's birthplace and date of death were not resolved until the Marlat book unveiled the findings from their years of research.  We now know he was born on February 5th, 1785 in the small central France town of Bellac. His father Pierre Parinaud would at the time of his marriage become Pierre Parinaud delacôe (or dit Lacote [alias Lacote]). As the Marlat's explain in their book, his son (our luthier) would choose to go by Pierre René Lacote (or just René Lacote), leaving off the circumflex above the "o" - thus, I have had to go back through my article and remove every instance of that "ô"!

Due to economic realities, Lacote relocated to Versailles in 1848, where, to supplement his guitar orders, he opened a linens and haberdashery shop, which he left to his wife to run. In 1859, Lacote closed this shop once both of his children had left home, moving to other shops to continue his occasional lutherie with his partner Eulry, who would pass away in 1864. Lacote would pass away in his newest home on February 10th, 1971.4b


The Décacorde

Though "ten-string" could be considered the literal English translation, Lacote's first extended range guitar - developed and patented in 1826 in collaboration with famed guitarist Fernando Carulli - was not a standard "ten-string" floating-bass guitar, as would soon become popular in Vienna.  In fact, the inventors sought to distance their creation from the “guitar” itself.5  Besides the unique headstock, neck design and sharping levers, this fascinating, though short-lived, instrument had a unique and distinctive tuning.  Only the top five guitar strings were tuned to standard and fretted.  From there the floating basses descended (from the A rather than an E) diatonically down to C. Only the C, F & G strings would have the half-step sharping lever "ditals." I find this a rather interesting early "harp guitar concept" – and have long wondered what it was used for, and why no one has ever duplicated or resurrected it to this day.6  While I originally assumed that it was intended as some new harp guitar variant to enable Carulli to reach new heights of virtuosity, I soon learned that almost the exact opposite was the intention.  It became clear that it was aimed more at the amateur or non-professional guitar player as something “easier to play than the guitar.”7  More on this in a moment, after we take a look at the instrument(s).

My information from the patent comes from the Marlat book and a recent (1985) analysis of the patent in an article by Danielle Ribouillault, translated from the French for me by Benoît Meulle-Stef.  Both tell us that Carulli was presenting the décacorde as an improvement of the standard guitar of the time, much louder because of its tuning (what he likely meant was the additional number of resonant bass strings within that tuning). Specifically, that the sympathetic, oscillating effect of the instrument had the effect of changing the sound and raising the general volume (this, of course, is the same boast – and usually a legitimate argument – used by most inventors and builders of harp guitars).  The patent states that “The seven open notes enter in resonance when one of the fretted strings are plucked and that with the fundamental, third, fifth and octave that’s very pleasant to the ear and makes the instrument sound much louder. The sound of the instrument is fuller and nicer than the one of the regular guitar.”

The “seven resonant open notes” in the sentence above are all seven lowest strings which are wound strings. Five are the unfretted bass (harp) strings; two are on the neck and fretted (see this tuning diagram).

Carulli's Décacorde tuning

 

In most specimens, as described as and shown in the patent (above), three levers were provided that could be turned to raise the pitch of certain bass strings a half step.  Additionally, in his method, Carulli allows that the tenth (C) string can be tuned down to B on occasion (Ophee), and other notes can be tuned to play in the flat keys (Verrett).  I have not examined any in person, but it is clear from the patent drawing and recent images from guitar experts Daniel Sinier and Françoise de Ridder that the levers pull the string down against the head to "fret" against the lower second nut.  While the patent drawing shows strings C, F & G in sharp position (and specifically mentions only these notes) Benoit Meulle-Stef examined a specimen in a Paris music shop and found that the levers rotated in both directions so that all basses could ostensibly be raised.

Sinier and de Ridder have pointed out that the décacorde was made in three different stringing configurations:

  • Those instruments that adhere to the Carulli patent have 5 strings on the fingerboard and 5 floating basses (1st row below). 

Other specimens that do not bear the patent stamp are known with:

  • 6 strings on the fingerboard and 4 floating basses, and

  • 7 strings on the fingerboard and 3 floating basses. 

Personally, I wonder if any of these latter instruments may have been configured, not as true Carulli Patent Décacordes, but as similar-appearing Lacote ten-strings tuned more traditionally, and perhaps, played "professionally." This is just my own theory (but a good one!), with no way to really answer.

 

By contrast, the Carulli Patent form of the décacorde was clearly created for the amateur guitarist, as stated by Carulli himself.  In wasn't intended for the professional guitar player at all, but for students, as something easier to play than a normal guitar.  Enthusiast Len Verrett writes on his site earlyromanticguitar.com that in Carulli's time, the guitar had very recently changed from a five-course instrument to a six-course instrument, and so having the top five strings the same may have seemed natural to many guitarists of the day.  I disagree.  From my (admittedly less) experience, I would say that by the mid-1820’s the guitar – both amateur and professional – had fully transitioned to 6 single strings, having at least five decades to slowly, then increasingly rapidly, make this segue.  In my analysis, Carulli was not so much adding to the five-course guitar, but “inventing” a new instrument that removed the added sixth fretted string (a seeming throwback to the older tuning) in order to “dumb down” (my words) the “extremely-difficult-to-play guitar” (Carulli’s words).  With only five remaining fretted strings, and adding new additional open basses, he was essentially revisiting the "easy-to-play" concept of the (English) guittar and the later harp-lute family, i.e.: a stringing/tuning configuration that required less effort and training to utilize than the “difficult” six-string guitar utilized by the virtuosos. He was also adding the then already-common practice of adding additional floating (open) bass strings, like most harp guitars known today.

While it might seem to many six-string guitar players that ten strings would be harder to play than six, Carulli’s premise was much the same as that of modern 20-string concert harp guitarist John Doan – that it actually required reduced effort, with comparatively less left hand work.  In fact, this was the key point of the patent, further demonstrated in the Méthode.  Carulli wrote that, while “the guitar is extremely difficult to play and requires a very long time of study and work,” in the décacorde the use of the left hand is simpler; with “the need to use just one or two fingers of the left hand, rarely three, never four” – due to many notes being instead played on the open strings and not fretted, thus making chords and arpeggios “extremely easy.”  Carulli is pointing out that his instrument offers voicings impossible on the guitar, including full chords using only a finger or two on the neck!  Indeed, we harp guitarists do that all the time!

Carulli's 1826 Méthode is surprisingly skimpy on additional details of the instrument.  I have included the pertinent introduction in a PDF linked at left.  The gist of it is similar to that already discussed.  “Easier to play” arpeggios and accompaniments being the selling point.  It begins with extremely rudimentary scales, chords and exercises, and progresses to more and more advanced pieces.  Included are a couple that require flipping the C and F levers during the piece.  To date, I don't know anyone who has actually attempted these pieces on an actual décacorde.  There doesn’t seem to be much time within the musical phrases to change some of these accidentals from natural to sharp and back “on the fly.”  Regarding the sharping levers, Ribouillault points out this caveat from Carulli:  If in a piece, there are some tonal changes which require a sharping of any of the basses, you have to use silence, or the end of a phrase, to move the sharping lever.  If you can’t find the time to do so, you have to play the note on the fretted strings."  Meaning, one may have to arbitrarily switch octaves, a somewhat amateurish musical undesirability, that limits the quality of the music and keys used in Carulli’s Méthode.

All in all, the décacorde may have quickly come and gone because it was somewhat of a “marketing gimmick.” As Ribouillault wrote, “the inventors were monetarily dependant on the amateur customers of the time, who wanted something undemanding to provide some pleasant effects without any great effort.” For all its hoopla, it was rarely if ever used in concert by Carulli.  How could he personally promote it? – surely he did not intend performing for the rest of his career using only his first two left hand fingers! Yet he went all out on this invention, enlisting the services of Lacote, the finest luthier in Paris. Clearly, he was not creating another Edward Light-style instrument intended for parlor novices, but a high class instrument capable of professional use. And despite his patent and Méthode verbiage about easy-to-play arpeggios and accompaniments, Carulli did write some professional pieces for the instrument.  Narcisco Yepes recorded the final Méthode pieces, the Diversisments largo and poco allegro, which Ribouillault describes as “music made to be played in the rich Parisian parlors of the era. The compositions are very similar to those for guitar of the same period - very classic, but already delicate with an awakening sensibility of the romantic period.”8

So the décacorde did skirt with legitimacy.  Still, there are almost no historical music players today with an interest in exploring this instrument and its repertoire.  Len Verrett and Michael Patilla (who went so far as to have a reproduction décacorde built by Jack Sanders) have long been looking for additional pieces that Carulli or others may have written for the instrument, but to no avail.

Originality of the specimens below: That question has come up several times and I expect it to linger. The Marlat book may now offer many additional clues concerning body plantilla, heads, bridges, rosettes and other clues. Some experts maintain that the headstock must have the Lacote stamp on the headstock (see image above). I have no idea, but can think of reasons why the iron stamp could be "missing." Frankly, I'm more interested in the many variations of the head (all original?) and bridges (all replacements?).

Patent Configuration

By "patent configuration" I mean those strung 5 open and 5 fretted, with 3 dital sharping levers. (In many cases, I am unable to tell whether the ditals were originally there or not, or are just missing.) The Marlats further stated that (stringing aside) around 1828 the headstock became straighter, without the obvious protruding bass side lobe. I myself actually see many different shapes, not just a lobed and straight version. I would appreciate others' help in putting these into a better chronology (with circa dates to match).

This interesting instrument is now in the Boston Museum of Fine Arts collection. As stated on their site, it was: "Purchased from Tony Bingham of London. Bingham purchased the instrument from a dealer in Paris, who had purchased it at auction at the Hotel Drouot. It had formerly belonged to Eugène Peletin of Paris, a student of the French guitar virtuoso Napoleon Coste."  This instrument was part of Coste's collection (or inventory) at the time of his widow's death, and most assume Coste installed the bridge/taipliece system and finger rest on all these instruments. This is one of the four Hotel Drouot 1995 auction instruments discussed (three pictured) in Sinier de Ridder's La Guitare, pp 55-56, where it is mistakenly identified as a décacorde.

While an original custom 9-string Lacote instrument does not sound outside the realm of possibility, such does not seem to be the case in this instance. Scholar Alex Timmernan (in the Guitar Summit forum) wrote this about the unusual 9-string:

"A case of ... modifications that are not that well executed (or) precise as one would expect Lacote himself (to) have done is a 9-string Lacote example currently in the Museum of Fine Arts in Boston (USA). Years before it was sold to the MFA, I had the chance to measure, describe and photograph it.  It shows alterations at the headstock, fingerboard and (to the) side of the fingerboard on the (soundboard).  In fact, the ... model of this instrument looks (more like one that originally had) less bass strings.  Therefore it is likely that the bridge/tailpiece device is also a later addition to the instrument (Coste?)."

Interestingly, an 8-string Lacote is specifically mentioned (with appraisal for the 1900 "vintage guitar" market!) by one Robert Fissore in Les maîtres Luthiers of 1900. (source: Westbrook: The Century That Shaped the Guitar)

I think everyone agrees that the earlier bissex headstock was the inspiration for the Carulli/Lacote Décacorde. 

It even had similar sharping levers. In this light, how much credit is really due Lacote for the Décacorde design?

Naderman, a harp maker, created this unique instrument that some consider the first dated "harp guitar." 

With its lute-shape and staved back, I consider it a hybrid harp guitar-like invention.

Napoléon Coste and the Heptacorde

By 1835, when the décacordes had fallen out of favor, Lacote began building heptacordes, at the suggestion of Napoléon Coste (1805-1883), shown here with his two different 7-string specimens. Coste, born in France in 1805, moved to Paris in 1830, where he quickly established himself as the leading French virtuoso guitarist.

Unlike the décacordes, these instruments were fairly standard guitars with an extra floating string tuned to D (occasionally C). The late expert Bruno Marlat provided evidence that Coste himself dubbed the instrument the "heptacorde," and gives 1835 as the first confirmed date of Coste's use of the instrument (though suspects it was in use earlier). 

Elsewhere (Phillip Bone: The Guitar and Mandolin), Fernando Sor was said to have requested the 7th string, but this has long since been completely debunked and scholars agree that there is much suspect information in Bone's book.9  Sor, along with famed fellow Spaniard Aguado, did work with Lacote on certain other details regarding the guitar's sound, however (its bridge, and internal second soundboard and external stand, respectively).

A good introduction to Coste and his music is the complete preface by Brian Jeffery (1982) in La Source du Lyson, op. 47
for solo guitar
published by Tecla Editions. Unfortunately, there is no mention of the heptacorde nor the floating string, other than one reference to a single low D that "can easily be put up an octave." (Indeed, Coste's "meets-minimum-requirements harp guitar" is all too often viewed today as an unnecessary option). Tecla also sells a new small French/English book on Coste.

According to Bruno Marlat (in the liner notes to Brigitte Zaczek's 2005 CD Romantic Guitar Vol. II, as translated by Steven Edminster), as early as 1835 "the use of a seventh string puts in an appearance" in Coste's opus 5, "Souvenirs de Flandres" (published with the support of Lacote). Marlat astutely noted that "even though this may simply have involved the exploitation of an older idea, people referred to it as an 'invention'."

Marlat cited additional provenance, including that Lacote "received a prize in 1839 for a seven-string guitar which was described as 'perfectly crafted, having in addition a very beautiful tone quality.'  At the next fair, in 1844, he presented 'several heptacorde guitars which are perfectly crafted and have a beautiful quality of tone, instruments which were awarded top ranking positions in the contest'."  Marlat concluded (as would I) that the specific name "heptacorde" came from Coste since "we read in the appendix on the seventh string which he added to his 'N. Coste’s New and Enlarged edition of Sor’s Guitar Method' the following statement: 'Some years ago I arranged to have built in the workshop of Mr. Lacote, a maker of stringed instruments in Paris, a guitar designed to yield a larger volume of tone and, above all, a more beautiful quality of tone. [….] I called this new type of guitar a Heptacorde'."  This then, is our proof on the origin of the heptacorde, if we take Coste at his word.  Unfortunately, Coste also claimed (in the introduction to his "25 Etudes de genre pour la guitare, opus 38" per Marlat) that "This improvement was immediately adopted and taken further in Vienna, Austria."  This claim seems rather boastful, as numerous players and builders in Vienna and elsewhere had been experimenting with 7, 8, and 9-string guitars from as early as 1809 and possibly before.

Early Heptacordes

There is not yet full consensus on how many of the surviving c.1835-c.1841 heptacordes are fully original. Marlat wrote: "The first seven-string guitars of Lacote differ little from his six-string models. The additional string is fitted in the theorbo manner as described by Coste: 'The seventh string, much longer than the others, is fitted at a certain distance outside the neck of the instrument and requires no change in playing technique'. In two of the three instruments we are familiar with, the fingerboard has five additional frets – 22 instead of the usual 17 – and reaches over the edge of the sound hole, extending the range to D5. An instrument of this kind, held gracefully by an elegant young woman, provides the frontispiece for the Sor/Coste method. A photograph of Coste...shows him posing with exactly the same model."  Below, I show first the illustrated model and Coste's early specimen that Marlat described. 

The next few extant instruments I show are believed to be authentic pre-1850 heptacordes. Some of these have been discovered quite recently (Hofmann's with its fascinating curling headstock, Renard's, and Coste's original instrument from Marlats' book). The Verrett specimen (since sold) and the Westbrook are similarly believed to be original. 

The last two have long since been established as "modified."

Still another recent discovery, this early Lacote may have had  6 or 7 strings originally. Regardless, it also was later modified with the "Coste" bridge system. Though not dated, the two labels include "the typical label and another manuscript one which reads "guitare heptachorde système Napoléon Coste."

Later Heptacordes

 Heptacorde, 1842

Surprisingly, this heptacorde, built in 1842, appears to have the more "modern" c.1845-c.1855s shape - much different than the 1841 instrument above, though similar to the c.1836-c.1839 instrument (with its short fretboard). When did this plantilla actually first appear?!

At far left is the instrument as found by the late Dave Evans, a luthier in Brussels. At near left is the restored instrument, owned now by performer David Jacques

The original bridge was missing. Westbrook believes that Coste did have something to do with this guitar, as it has his signature is on the back of the head.  Perhaps he raised and extended the fingerboard?

Heptacorde, 1846

At right is an 1846 Lacote. Note that neither the 1842 at left nor this original instrument was modified by Coste, and that both have an extended fretboard with 22 frets.

1846 heptacorde sold by Vichy Auctions in 2015.

Soon after Lacote again won bronze for his heptacordes in 1844, more striking new features appeared, some once again instigated by Coste. As described by Marlat: "The shape of the body is broader with a less narrow waist than the usual Lacote designs; the fingerboard has 24 frets covering four octaves and the lower part rests on (standoffs) and is not in direct contact with the soundboard; the strings pass over the bridge and are fastened to a tailpiece at the end of the body; a bar of maple is glued on at two contact points parallel to the first string, perhaps as a kind of support for the little finger. The whole instrument seems to be designed with a view to allowing its soundboard to vibrate as freely as possible."

Marlat continued, "This description could well apply also to a Lacote heptacorde kept in the Paris Museum of Music (shown below) where a handwritten note tells us that this is 'the favorite guitar of Mr. Napoléon Coste. The bridge has been applied by the remarkable composer and professor himself'.  It would thus seem that Coste was not only the inventor and designer of this bridge/tailpiece system but actually built it himself."

This "smoking gun" bit of provenance (that the unique bridge was built by Coste) stirs up a secondary topic and ongoing discussion/study involving Lacote instruments.  Specifically:

  • Have we identified / can we even identify all the modifications?

  • Are any "Coste-style" bridge systems original?  Or were all built "after the fact"?  Why?

  • Who did the modifications: Lacote, Coste, or other?

  • How can there be so many of these modified instruments?

  • What other modifications did Coste or others make?

I already mentioned above that some experts are still not positive that the extant early early heptacordes are all fully original. I now ask the question again regarding the later heptacordes. Are they original"? Can any be considered original, unless shown that Lacote himself installed the specialized Coste-style bridge system when new? How do we resolve this? As I discuss shortly, perhaps we can't.


Mr. Eugène Petetin

Before we examine the next instruments, I need to briefly mention this man, who figures prominently in the provenance of so many of the surviving Coste instruments. Petetin was a naval officer and amateur guitarist who some believe to have been a close friend of Coste and his wife, and presumably one of Coste's guitar students. On the other hand, the Marlats question this, saying Petetin "likely never actually met Coste prior to the 1870's" (just before his death). Several instruments were apparently given to him by Coste's widow, and perhaps he received others after her own death. Petetin appears to have made handwritten notations (sometimes fairly cryptic) on paper and glued these over the original labels (if present) on the instruments once in his possession. Debatable is whether the information provided by Petetin is worth losing the label information! The converted 1828 6-string above is one of these.  Another four of Petetin's instruments surfaced in 1995 at a Paris auction, and were dispersed. Of these, one (missing from the group photo at right) ended up in the Cite de la Musique museum - the original "smoking gun" instrument mentioned by Marlat above. The 9-string made its way to the Boston MFA, and the other two are shown below and described by Sinier and de Ridder in La Guitare

Three of the four 1995 Auction instruments. I am confused by the fact that all three appear to have the same rosette, though the left instrument is by "Olry" (see below) and the others by Lacote - perhaps they are just similar? All are believed to have bridge/tailpiece modifications by Coste, with all but the modified 9-string (discussed above, following the Décacordes) having the finger rest. Are the fingerboards also Coste replacements?

 
Lacote Heptacorde, all original, not modified by Coste, c.1845-c.1849

All four images above show Coste's second known Lacote Heptacorde throughout its life. This is the instrument with Petetin's handwritten note stating the bridge system is "Coste's own invention and work," which is likely not true. As the Marlats point out in their book, this instrument has no string holes in the top under the bridge, verifying that this Coste-styte bridge was original to the instrument. It furthermore shows refinements pointing to Lacote himself being the original luthier of its components. Their conclusion is that Petetin was in error when he wrote his inscription "at least thirty years after the instrument's construction."

Coste Modified Bridge and Tailpiece System

I am, frankly, out of my element here, and rely on the research and expertise of others, where I do not always find consensus. One thing seems certain. If Coste owned all the instruments that we find with "his" bridges, then he was quite the guitar collector! More likely, Coste installed his modifications on instruments destined for his pupils or other patrons, and perhaps the "Coste modification" was duplicated by others. The question of whether Lacote himself installed such systems for Coste (and which specimens, and when) is not easily answered. Did Lacote - with Coste's input - in fact build the first such prototype? Some evidence points to yes. As for all the many other instruments shown below (including many makers besides altered Lacotes), Marlats give this quote from Coste himself, speaking of his vast instrument collection: "I can still undertake some of the modifications on my instruments. I have a student who assists me a great deal in this. I have a superb collection of guitars that have undergone such transformations."

Alex Timmerman speculates that Lacote did perhaps construct some of these bridges and was "among the first" to do so, explaining that "the original Lacote guitars I have seen with this bridge/tailpiece type show good craftsmanship."

Sinier and de Ridder do not believe that Lacote made these modified bridges himself as none of these features are in "Lacote's manner, style, techniques, acoustic principles, choice of wood, varnish, etc."  While acknowledging the possibility that Lacote may have constructed the first one or more custom bridges suggested by Coste, they believe that Coste otherwise made all these bridges and tailpieces himself. They are convinced that both the concept and craftsmanship on the examples pictured in Coste's photograph and surviving specimens is Coste's own. Besides the finer details, they point out an obvious clue - that they have never heard of any Lacote guitar with an "original 'Coste' bridge" that has no holes in the top - i.e.: the holes from Lacote's original pin bridge are always present. However, an exception can be plainly seen in Kresse's specimen, seen here. They suggest that Coste modified such guitars for his own use and for the many students, friends, and customers that he had throughout his long career. And indeed, there are far too many such instruments for Coste to have owned them all!

Bruno Marlat: "While it may seem unlikely that all these modified instruments actually belonged to Coste, one might well imagine that the teacher had a hand in modifying guitars intended for the use of his pupils."

James Westbrook: "No doubt Coste had a large amount of instruments, but also a massive following of disciples that needed to acquire 7-string instruments one way or another."

Bernhard Kresse (regarding his 1855 specimen): "There remains the possibility that Lacote did 80% of the work and left for Coste the making and installation of the bridge, tailpiece and finger rest. Possible but unlikely. These additional parts of the guitar are made with the same accuracy as the rest of the instrument. Further, the varnish doesn’t show any difference in color under fluorescent light. By the way, the construction of the neck and fingerboard, its final calculation of thickness, respecting the right angle and the difference of treble/bass side requires an early presence of the bridge during the construction process."

Clearly, we can see from the above discussion (and more below) that there is little consensus on this question - partly because of differing conclusions from the analysis of the same instruments but also largely due to the fact that there are so many different and inconsistent specimens that are being referred to. The only way I can see to resolve it would be to get all of these instruments and experts into the same room and start comparing instruments and notes!

Sinier and de Ridder believe that Coste also sometimes  modified the fingerboards and the heads of certain instruments.

Napoléon Coste seems to have modified nearly every instrument he acquired. Here are a few additional non-Lacote instruments known or suspected to have had the "Coste touch."

At left is the wonderful "baritone" guitar Coste is pictured with in the famous photo, now in the Cite de la Musique museum. Note his same bridge and tailpiece system and the elevated maple finger rest -elongated as needed!  It is not labeled, and no one has conjectured as to the builder. Sinier and de Ridder are convinced that it was built by Coste himself

At lower left is an instrument from Coste's estate that he also modified. The maker's name, Olry, is handwritten on an affixed label. According to Françoise de Ridder, this Olry may be the same maker as the heptacorde above that has a handwritten note applied that reads “Eulry.” After their book was published, they received confirmation from Matanya Ophee that the Russian pronunciation of both “Eulry” and “Olry” are the same (and similar in French), and that it is therefore a  transcription error from oral to written language. See La Guitare (Sinier de Ridder), p.55-56.10

At right is a Schenk bogengitarre (in the Brussels Museum), one of the well known hollow arm harp guitars that inspired Mozzani. It has a replaced Coste-style bridge as well. The conclusion some jump to is that Coste owned and played it as well, but as stated by the many experts on this page, there is usually no way to know - and we doubt Coste could have owned all of these!

About the Schenk, Françoise de Ridder (in the Guitar Summit forum) wrote: "Without any doubt, Coste made this bridge, and you can see the two little pins (that) supported the missing piece of wood for the finger (rest)."

Alex Timmerman replied (also in the forum): "The Brussels Schenk guitar now shows a bridge made out of two saddles on either side of (what used to be) a tie-block through which the strings are lead towards a tail-piece where they are fastened. The finest examples of this bridge design, are of course seen on the guitars made by Lacote himself. The idea of replacing the old pin-bridge could be for reasons of spreading the tension that is caused by the extra added strings on Bass guitars. Lacote might have been among the first to install this kind of maple 'bridge/tailpiece' model on his bass guitars. What I can add to this is that among other things the bridge (à la Coste) on the Friedrich Schenk guitar at the MIM in Brussels is again not made to the high quality like those of the same type seen on the Lacote guitars."

In 2008, a 6-string Lacote-style instrument appeared that was built by Valance and modified later - again, possibly by Coste (below left). According to owners Sinier and de Ridder, "the luthier Valance, after a brief period in the workshop of Lacote, built pretty guitars in the style of Mirecourt." Additional images

In 2017, another Valance was seen in the Paris shop of Arguence Lutherie, which is now in the collection of Eric Mry (at right). Note its headstock; was this also a modification, or was it an original 7-string? Perhaps the clue is that is also has the same Coste-style modifications.

Besides my obvious fascination with the harp guitars, there are a host of other important and fascinating Lacote innovations that can be seen in the Marlat book - including Lacote's custom, enclosed tuners, a double soundboard, and adjustable micro-frets for each string!

A Unique Lacote Décacorde

Lacote / Coste Heptacorde

Footnotes

1. Multi-string (or my preference, Multi-course) Guitar is a commonly used term for guitars with more than six strings - yes, it is technically illogical, as all guitars have "multiple" strings. Extended Range Guitar may be a little more logical than the previous, though is also unspecific.  Bass Guitar is scholar Alex Timmerman's preferred vernacular for guitars with extra bass strings - much like my own Harp Guitar, which today most consider both vernacular and a newly defined and classified organological term.  Please note that none of these four terms were used historically, and all have one detractor or another.

2. Yes, the literal English translations would be "seven-string" and "ten-string" respectively, but in this case I believe that the guitar community  agrees (by mutual, if unspoken, consensus) that the French word for each of these newly-invented instruments acquired a new meaning as a "multi-language specific name."  Personally, I find this another fascinating semantic topic that has yet to be addressed or discussed.

3. As most serious readers know, I prefer using "course" in place of "string." (seven-course, ten-course)

4. Again, I don't duplicate the Marlat book material here, I only draw from it. The first thing they clarified was that the luthier's name was Pierre René Lacote, not François René Lacote (or René François), as was once stated by many guitar historians. 

4B. As James Westbrook once pointed out, "One person (probably Bone, or some violin dictionary) wrote the date of  Lacote's death as 1855 and everyone took it as gospel, which I know is incorrect. For decades then, people either wrote that or "after 1855," which, while accurate, wasn't much help!  Sinier and Françoise de Ridder finally told us that Lacote lived at least until he was 83 with "his last known guitar...dated 1868." The Marlats once again settled the matter with 1971.

5. Per Marlat, the décacorde was Carulli's idea, that he brought to Lacote. Lacote devised the sharping dital levers and design, including the full length cut out trough for the thumb. Curiously, only the C, F and G strings of the five basses would have sharping levers for different keys. Carulli and Lacote jointly submitted the patent on Oct 31 1826, which was granted Dec 15 of the same year. I They exhibited the instrument at the Exhibition of Products of French Industry in 1827 but it went unrewarded. In 1831 a Paris teacher Mr. Amory placed an ad extolling its virtues - this was its very last gasp. The "failed" invention nevertheless brought Lacote's name to both amateur and professional guitarists.

6. In fact, I am continually surprised to find that virtually every guitar researcher and writer lumps the décacorde in with other "10-string guitars," when it is such a distinctly different, specific instrument.  It is casually lumped in with the original Viennese 10-string harp (bass) guitars, and even more disconcertingly, with today’s’ fully-fretted 10-string guitars (in all tuning configurations, Yepes or other) – as if the simple coincidence that it has ten strings is proof of some sort of ancestry or commonality.  I find this as laughable as all the Wikipedia entries that try to “define” various guitar "types" simply by number of strings - but was encouraged by the author of the Yepes section of the Wikipedia "10-string guitar" entry, who succinctly states, "One cannot consider as synonymous (just because they have the same number of strings) different instruments that do not have a commonly accessible original repertoire, that approach music through different performance practices (different techniques, especially with respect to the use of the 7th string, open and stopped strings), different instruments that are not only tuned differently but strung differently.  The true modern 10-string guitar is as little defined by its number of strings for their own sake, divorced from their singular tuning, as a piano is defined by its number of keys."

7. In his method, Carulli pointed out that his instrument was designed for amateurs, being easier to play chords "to accompany romances or ariettas." He also highlighted the tone of the open strings, saying that they helped increase the "instrument's volume nearly by half and at the same time renders it more harmonious and richer than the ordinary Guitar." I further noted that the inventors seem to have rarely said “than the regular or six-string guitar – just “Guitar,” to further demonstrate that their décacorde was a different instrument than the now-standard 6-string guitar.

8. It is a coincidence that Carulli’s and Yepes’ instruments were both ten-string guitars.  Yepes’ was founded on a much different (and obviously more acceptable) concept, with a completely different tuning configuration, which just happened to have the exact range (down to C) required for the Carulli pieces.  However, the pieces would have a somewhat different sonority when played on the two instruments, due to the different open strings.

9. To this day, the Wikipedia "Harp Guitar" entry includes Sor, and there seems to be little we can do about it! In fact, other than (rather ironically) his famed use of the harpolyre, Sor appears to have been a critic of extra strings, writing in his Method:

“à employer toutes les facultés de la main gauche pour la mélodie (…) fait éprouver aux guitarists de grandes difficultés lorsqu’il s’agit d’y ajouter une basse correcte, si elle ne se trouve dans les cordes à vide (…). On a cru remédier à cet inconvenient en ajoutant à la guitare un nombre de cordes filées, mais ne serait-il pas plus simple d’apprendre à se server des six? Ajoutez des ressources à un instrument lorsque vous aurez tiré autant de parti que possible de celles qu’il vous offer; mais ne lui attribuez pas ce que vous devriez vous attributer à vous-même.”

(“By employing all the possibilities of the left hand for the melody (…) makes the guitar player feel a great difficulty when he has to add a correct bass when it is not on the open strings (…) it has been tried to correct that by adding to the guitar several bass strings - but wouldn’t it be easier just to learn how to use the six? Add resources to an instrument when you have used all the ones it  has to offer. But don’t project on it what you should expect from yourself.”)

10. It is interesting to compare the interpretation of  the label text by three different examiners. Sinier and de Ridder believe that the label was written by Olry himself and reads "Olry luthier, rue des 3 cailloux, n° 42 (3 pebbles street) à Amiens année 1850." 

Alex Timmerman examined the instrument at one time as well and presumed also that the label was by Olry himself. However, he read the label as "fait par Olry, Samier / rue des trois Castro no. 42 / a Amiens anneé 1850" (thinking Samier being Olry's first name). 

Erik Hofmann confirms that the address is "Rue des 3 cailloux, n°42" ("an address which actually existed, and still does") and also sees "Olry, Luthier." Hofmann further provides Olry's first name (Louis). Neither Hofmann nor Catherine Marlat know where "Samier" came from.

However, there are rumors of new evidence regarding both of these cryptic names ("Olry" and "Eulry").

Updates:
