2.2 Scheme functions

Scheme functions are Scheme procedures that can create Scheme expressions from input written in LilyPond syntax. They can be called in pretty much all places where using ‘#’ for specifying a value in Scheme syntax is allowed. While Scheme has functions of its own, this chapter is concerned with syntactic functions, functions that receive arguments specified in LilyPond syntax.
