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][alda-blog-post] for a brief history and rationale.)
