Thank you. But if I have to do all the \Score \accepts stuff,
then I guess I don't understand what '\alias ChordNames' does in
your example. I'd like to find a simple way of declaring that
"my custom context X is just like built-in context Y, except that
it modifies these settings." The appeal of that goes downhill
quickly if there are loose ends that have to be tied back into
Lilypond internals.
Is there a way I can define a context based on ChordNames and
have it automatically inherit all of the properties of a
ChordNames context, except the ones that I specifically change in
my custom definition? In other words, a way to eliminate the
need for the second \context {} block in your example?
