A music programming language for musicians. :notes:
Alda is a text-based programming language for music composition. It allows you to compose and play back music using only your text editor and the command line.
piano: o3 g8 a b > c d e f+ g | a b > c d e f+ g4 g8 f+ e d c < b a g | f+ e d c < b a g4 << g1/>g/>g/b/>d/g
For more examples, see these example scores.
The language's design equally favors aesthetics, flexibility and ease of use.
(Why compose music this way instead of in a graphical sheet music notation program? See this blog post for a brief history and rationale.)
