Re: Music function help

Many thanks, David! A perfectly clear explanation. I suspect I will be using \displayLilyMusic much more often in the future.

Braces are never optional.  They form sequential music expressions.  If
the sequence only contains a single music _expression_, there may not be
much of a difference in interpretation but there is still a difference
in _expression_: if you use \displayLilyMusic, you'll see that every pair
of braces inside is getting reproduced faithfully.

In your example, you used braces to combine your music arguments into a
single _expression_, and as a single _expression_, it would only serve for
one of your music arguments.
