Yepes' ten-string guitar The extended-range classical guitar is a
classical guitar with additional strings, normally extra bass strings past the bass E string, that are available on the fingerboard. Many configurations have been produced, but the ten-string classical guitar received a particular boost in 1964, when
Narciso Yepes performed the
Concierto de Aranjuez with the Berlin Philharmonic Orchestra , using a ten-string guitar invented by Yepes in collaboration with
José Ramírez III, with a specific tuning designed to supply sympathetic string resonance to all twelve notes of the
chromatic scale, in unison with any note played on the treble strings. This was significant for two reasons: • The endorsement of an artist of Yepes' calibre drew attention to the instrument, and demonstrated its capabilities. Starting in 1963, and for the rest of his life, Yepes used only the ten-string guitar in recording and performance. • The availability of high-quality ten-string classical guitars from the
Ramírez Company allowed and encouraged other performers to investigate the instrument. The use of the ten-string classical guitar is similar to that of the harp guitar: • Six-string guitar music can be played on the first six strings, but with added resonance from the extra strings. This was Yepes' original intention and the reason for the design. • Music specifically arranged for the instrument can make use of the extra strings directly, thus: • Music originally written for instruments with more than six strings can be more faithfully transcribed. Music written by
Bach and his contemporaries for
lute is of particular interest in this regard. The bass strings can be appropriately tuned. • New music specifically written for the ten-string guitar can make use of the extra strings however the composer might wish. Unlike the
harp guitar, the extended-range classical guitar has a single neck and allows all strings to be fretted. While the six-string classical guitar remains the standard and most common instrument, since 1963 ten-string guitars in similar configuration to the original Ramírez have been adopted by many classical guitarists and produced by several first-class luthiers, using both Yepes' original tuning and others. In January 2009, Gadotti Guitars announced the 10 String Nylon King Electric, a solid body, nylon-stringed ten-string guitar, suitable for both Yepes and other tunings such as the Baroque. A ten-string
jazz guitar by Mike Shishkov, based on the ten-string extended-range classical guitar, was demonstrated at the 3rd International Ten String Guitar Festival in October 2008.
Ten string electric guitar These guitars are either custom-made or produced in small quantities due to the very niche market they are intended for. Most of these instruments are tuned like nine string guitars with either an extra High A string or an extra Low G# string, in that arrangement for the latter : G# ,C#, F#, B, E, A, D, G, B, E. == Five- and six-coursed guitars with ten strings ==
