Charles,

I think that the internal chord structure should be chosen to meet musical
needs, not to match input syntax needs.  We can adjust the input syntax as
needed.

The discussion about the chord structure should probably take place on
lilypond-user.  I'm certainly not the one who should make the decision.

Please raise the issue on lilypond-user.

Thanks,

Carl
