Kenneth,

If you want, send your code to me and I shall try to achieve what you want with an \
explanation.

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
