Nota: LilyPond is a text-based music engraver; it is more similar to a programming language than a graphical score editing program. Before downloading LilyPond, please read about our Entrada de text. Once you have downloaded LilyPond, read the start of the Learning for a gentle introduction on how to install it and use it.
Nota: We do not recommend that you attempt to build LilyPond yourself; almost all user needs are better met with the pre-built version.
