This week was fun because I transitioned into writing the procedural music code in LISP (specifically hylang) instead of directly in Python. I re-used an old algorithm from Pure Data for doing stochastic fractal melody generation and re-implemented it:

(defn make-fractal-sequence [sequence-length number-of-notes &optional [basic-sequence-length 4] [sparseness-probability 0.75]]
(let [[basic-sequence (random.sample (range number-of-notes) basic-sequence-length)]]
    (list-comp
      (if (> (random.random) sparseness-probability)
        nil
        (get basic-sequence (% (int (/ t (random.choice [1 2 4]))) (len basic-sequence))))
      [t (xrange sequence-length)])))
