_expression_ and synthesizing a new one from it. There are no convincing
user-level tools for deconstruction of a music _expression_ short of
picking everything apart in Scheme via ly:music-property and its ilk.
There is some half-Scheme approach called with-music-match in the
display-lily code. Turning this into a proper and usefully powerful
method working with LilyPond syntax templates, possibly combining it
with the pattern-matching module available for GUILE would be an
interesting task.
But without a well-accessible more general transformation tool, I don't
really see a real user-accessible solution that would not start from
single pitches, thus not needing to deconstruct anything.
