Final Composition

Song Structure Determined By Algorithms

This grammar is context - free because the outcome of each random decision made is not affected by or affects other decisions made.

The grammar allows like rhythms to be grouped together and chosen between, to maintain a stylistic control, but is still gives an algorithmic construction.

Cumulative Probabilities determine which melody to be played. While it is possible to have give preferable melodies higher probabilities for construction, randomness and chance still make the ultimate decision in this algorithm.
