Sonata for Solo Violin; the fourth movement Presto contains quarter-tones, but they are not "structural features."[9] This movement also calls for third-tones.
Violin Concerto No. 2; the cadenza in the first movement requires the use of quarter-tones, but only as an effect.[10]
Divination by Mirrors for Saw and Strings. Strings are divided into two groups of 13 tuned 1/4 step apart. Each group plays only in its own pitch "universe". The featured bowed saw freely moves from standard tuning to pitches a 1/4 step away. Premiered at Merkin Concert Hall, New York City, 1998 by the New York Virtuosi and Dale Stuckenbruck saw soloist.[41]

^Tucker 1970, p. 7, "An arrow head pointing down over a note lowers it approximately a quarter step". Hettrick 1971, "Both pieces require performing techniques not encountered in traditional music for recorder. The most striking is the production of quarter-tones, notated as pitches in the chromatic scale to be lowered slightly. Charts provided by the composer give fingering for all half- and quarter-tones from the low f' up to a precarious c''''."
