lilypond

The music type setting software system I used to write music on computer.

• I use it even more than pen and paper. My music composing tools now is only recorder and lilypond

Lilypond is like latex, it got its own programming language, with variables and stuff.

• manuals
• basics
• learning manual
• notation/syntax reference
