For tunes that were created with LilyPond by Chris Maden, if you want to use the source files, you will typically four files:
tune_name.ly(the “wrapper file”)tune_name_tune.ly(the main source file)tunes.ly(an included library for traditional tunes)swing.ly(for some tunes, used to generate uneven eight-note rhythms in the MIDI output while keeping “straight” written notation)
If these files are all in one directory, you should be able to call lilypond on the wrapper file:
lilypond tune_name.ly
and it should generate tune_name.pdf and tune_name.midi as output. The PDF file will contain just the tune sheet music; the MIDI file will have a large number of repetitions of the tune, typically ten. You can adjust the tempo of the MIDI files by altering the line in the wrapper file, for example:
theTempo = #(ly:make-moment 240 4)
means there are 240 quarter-notes (4) to each minute. For a jig, a line might look like:
theTempo = #(ly:make-moment 420 8)
meaning 420 eighth-notes per minute.
