Rhythmic Recursion
summary
Rewrites Steve Reich’s clapping piece as runnable Ruby: represents the fixed part and the changing part as arrays of ones and zeros, maps 1→clap 0→rest, uses Sonic Pi to sound the patterns, and implements the phasing as a recursive loop that rotate and thread for concurrent parts (demo repeats each bar four times instead of Reich’s twelve). Code logs each section, plays both voices in parallel, and produces the intended phased rhythm live.
