Re: Learning how to use "\change Staff"; don't get it yet, obviously

[Kenneth Wolcott]

Hi Mark;

  Thank you for the help.

  I'm still having trouble wrapping my head around this.

  I think that the problem (in general) with my being able to apply
examples from the documentation to my engraving attempts is that the
example is not large enough (not enough notes, too minimal) to require
its own variable to contain the notes, so that gets in the way of the
Lilypond feature that I want to use.

  I will try removing the variables and just place the notes for the
first measure only to see if I can finally make this work, and
generalize it later.

Thanks,
Ken
