This program generates and plays a 440 Hz tone for 5 seconds. It can be extended to generate the spectrum of notes with a frequency table or the frequency formula. Because the rewards in Send are idealized ocean waves, they can also be represented as tones. Each level has a tone in its goal and a tone based on where the player's disc lands. Both play at the end of a level, sounding harmonic for a close shot and discordant for a near miss. The game can dynamically create these tones using the program as a basis.

I'm also building an algorithmically generated song: Silk Routes (Scissored). Here is an example of how it sounds so far.
