Piano Chord Progressions

This CD presents several piano works by Philip Glass, played with grace and enthusiasm by Aleck Karis. Wichita Vortex Sutra (1988) was inspired by the poem of the same title by Allen Ginsburg from 1966, which alternates between images of a road across the U.S. and a protest against the war in Vietnam. The basis of the music is a simple Protestant-like hymn tune with chromatic passing tones. This is treated to rhythmic syncopation and, at other times, is surrounded by quickly arpeggiated patterns. The Metamorphosis (1988), with the title from Kafka's famous work, is in five movements. Each movement has simple melodies and a simple set of chords, usually four in number, with chromatic changes between them. These "changes" happen through the addition of a chord or other simple alteration.
