2.3.1 Music function definitions

The general form for defining music functions is:

function =
     (arg1 arg2 …)
     (type1? type2? …)

quite in analogy to Scheme function definitions. More often than not, body will be a LilyPond code block.

For a list of available type predicates, see Predefined type predicates.
