Re: fingering

[Mark Polesky]

James,

You're "funneling two different
music expressions into one context",
but you've not explicitly instantiated a voice context.
See http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Creating-contexts
and 
http://lilypond.org/doc/v2.12/Documentation/user/lilypond-learning/Explicitly-instantiating-voices

In general, it is a good idea to instantiate voices explicitly.
Many LilyPond "purists" feel that automatic voice-instantiation
makes it easier for novices, but causes headaches later on.
Writing this:
   {c}
is valid syntax, but once things get moderately complex (which
usually doesn't take long), then using this syntax:
   { \new Voice = "A" { c } }
      -or-
   { \context Voice = "A"  { c } }
is safer.

Note that when you add
   \new Voice = "A"
you no longer need the #'add-stem-support command.

Hope this helps.
