Bogosort Sheds Arabesque No. 1 Until it Sorts the List

Bogosort plays over the changes to Debussy's "Arabesque No. 1" until it sorts the list.

The chord changes are from the first 16 bars of Arabesque No. 1 (looped).
________

The Bogosort algorithm is as follows:

1. Randomly shuffle the list.
2. Check if the list is sorted.
3. If not, go back to 1.

For a list of n elements, there is a 1/n! chance that Bogosort successfully sorts the list on any given pass, since there are n! (n factorial) possible permutations of the list. So with six elements, the probability of the list being sorted on any given pass is 1/6! = 1/720 ≈ 0.00139.

In this instance, the algorithm took 1051 passes to sort the list.

The six elements of the list are mapped to notes of a specific scale or chord, depending on which chord is being played in the progression.

The shuffling algorithm used is the Fisher–Yates Shuffle, from lowest index to highest. The note played is the value of the element at the current index in the outer for-loop of the shuffle algorithm.
