Thank you very much. Changing it to ly:pitch takes care of it. I had
been going by the examples at
http://lilypond.org/doc/v2.16/Documentation/notation/substitution-function-examples
and the only one there that had a note used ly:music. When should you
use ly:pitch and when should you use ly:music? (Is there a place in
the documentation that is good for learning these things?)
