The Scheme interpreter and I disagree.  For starters, you removed the
opening paren of the function call.

a b c in normal source is shorthand for something like a8 b8 c8.  In
the music function, the pitches are all that is there.  They are not
shorthand for notes.

No idea, but it should be good enough.  If you actually want to take
notes as arguments (possibly including durations and articulations and
other stuff), just declare your arguments as ly:music? instead of
ly:pitch?.
