Our listening example by Ligeti features a compositional technique the he developed called micropolyphony. You’ll find a number of musical terms referenced in this article. Two that I particularly want you to understand are canon and cluster chord. Canon is a strict form of imitative polyphony (linear or horizontal), while a cluster chord is a harmonic structure (vertical).<\/p>\n
