MusicCreator - Rhythm Generation

MusicCreator uses a very simple algorithm to determine the rhythm. This algorithm balances randomness with structure.

1. Create measure A.
   1. Start with n eighth-notes, where n is calculated from the time-signature.
   2. Randomly choose an eighth-note and combine it with the next eigth-note.
   3. Repeat step b two more times. Note that it is allowed to choose a note twice. Therefore the end-result may end up with 1-3 combinations. The maximum length note that can be created is a half-note, if three adjacent eighth-notes are chosen.
2. Repeat step 1 to create a measure B.
3. The first and last measures are then "tacked on" to the beginning and end. They are artifically constrained to be whole notes (or the equivalent, depending on the time-signature).
