String Quartet,Fugue and Variation

A String Quartet consists of four voices playing together with distinct parts for each voice.
A Fugue is a contrapuntal composition for a fixed number of voices.
A Variation has a fundamental musical theme repeated in an altered form or accompanied in a different way.
Please notice that patterns are varied in an iterative way. Some of the most beautiful western music that was ever composed varies a pattern in an iterative way.
This same iterative variation is also evident in nature.
