I don't know where you saw this on the lists, but attached you'll find
a solution.

I wrote a markup command which takes a music expression and finds the
relevant information.  In the example, I show two ways of using it, as
a top-level-markup and as a mark.  (The mark will have better
alignment possibilities.  It's not hard to get it over the treble
clef, for example.)

Hope this helps!

P. S. It's probably possible to write an engraver for this.
P. P. S.  I avoided the function note-name->markup because I don't
like the gap it creates between note name and accidental.  My code
could use some height adjustment for accidentals, though.
