INTERLUDIO (1968) for 10-string guitar by Leon Schidlowsky (ed. Viktor van Niekerk)


One of the earliest compositions for the ten-string guitar of Narciso Yepes is now available in an edition published by the Israel Music Institute.

Dating from 1968, Chilean-Israeli composer Leon Schidlowsky‘s Interludio was written for Yepes and his guitar in a graphic ‘space-time’ notation widely adopted during the 1960s when Western art music entered its ‘liquid’ (or ‘post-‘) modern phase.

Excerpt from INTERLUDIO by Leon Schidlowsky (ed. Viktor van Niekerk), Israel Music Institute.

Schidlowsky originally notated Interludio across two staves with (transposing) treble and bass clefs. However, one of the composer-approved changes to the score was the relocation of all notes played on strings 1-6 to the upper staff, and all notes played on strings 7-10 to the lower one. This allowed us to minimize string and fingering indications (and thus limit entropy) in an already cluttered score. (Strings 7-10 are only indicated when fretted.) Incidentally, in Interludio, strings 7-10 are used over 120 times in the space of about 2’12”, making for a challenging addition to the repertoire of the virtuoso ten-string guitarist. The piece also provides extensive opportunities for the use of Yepes techniques like prestissimo flourishes with three fingers of the right hand, and cross-string trills.

The score is available from the Israel Music Institute*, catalogue number IMI 8002: http://imi.org.il/by_instrument.php?cat=guitar%20solo

A few minor errata have to be pointed out:

  • Bar 41: either slur or attack the G#, but of course not both.
  • Bar 115: the arrow indicating the simultaneous playing of two strings (8-7) by the right-hand thumb should point down.
  • Bars 122-23: left hand fingering (3 4) should be 4 then 3.
  • The explanation of symbols used in the score has been omitted; I include both Schidlowsky’s original Spanish instructions and my English version below.
