Dancing in the Dark

for digital sounds

The pitches for this piece are those found in a scale based on twenty equal divisions of a perfect fifth, with middle-C as the tonic. Each of these divisions is slightly larger than an interval of 35 cents, and the result is very similar to Wendy Carlos's gamma tuning. A special property of this scale is that it can be used to form very pure major and minor thirds, and so the tertian harmonies used in this piece are therefore quite clear and beautiful.

Neptune Flyby

for digital sounds

This piece is for the most part constructed of pitches in 12-TET. However, there are occasional microtonal embellishments, as heard in this 68 second audio clip: mp3 File (1 MB)

"Lament for renown and grace"

from the
Suite from "MacBeth"

for digital sounds

The pitches for this piece are those found in a scale based on nineteen equal divisions of octave (i.e., 19-TET). A special property of this scale is that it can be used to form very pure minor thirds and major sixths. As this movement illustrates, it also provides more than the usual complement of chromatic embellishing pitches.

"Midnight madness"

from the
Suite from "MacBeth"

for digital sounds

This movement is definitely xenharmonic. Its most salient feature is an apparently endlessly descending set of glissandi (an example of an aural illusion known as Shepard tones).
