Markov Chain Chord Generator

Archie's EPQ
Chord Sequence (Loop)

Click a chord to hear it and add it to the sequence. The loop defines the transition matrix.

Chaos Theory — Sensitivity to Initial Conditions

Two sequences from nearly identical starting conditions diverge dramatically — the butterfly effect applied to chord progressions.

Fibonacci — Golden Ratio Generation

Combine Fibonacci-based generation methods. Toggle any combination — if none active, falls back to Markov.

Fibonacci Rhythm
Chord durations follow 1, 1, 2, 3, 5, 8 beats (cycling)
Fibonacci Selection
Chord at step n = fib(n) mod numChords — spiralling patterns
Golden Ratio Weighting
Transition weights ranked by powers of phi — steeper hierarchy
