Yes, it's Scheme (a LISP dialect) which is used in Lilypond to 
implement many different features, using the Scheme interpreter
Guile. More information on Scheme, including a reference manual,
is available at
http://www.cs.indiana.edu/scheme-repository/home.html

On my Debian system, the reference manual is also available
in the package r5rs-doc.
