Is there a non-verbose way to notate finger sustained notes in LilyPond?

Question

I recently started learning LilyPond and am trying to notate finger sustained notes as described in Is there piano notation for finger sustained notes (as opposed to pedal sustain)?. I would be fine with either one of the notations from the top two answers.

I was able to notate what's described in the second answer like so:

\relative f' { f4~ <f c'>~ <f c' f>2 }

I find the code I wrote very verbose because I have to repeat all of the previous notes whenever I add a new one. Ideally I would only need to specify the next note and that I'd like the previous notes to continue and tie over. Is there a less verbose way to express this or what's described in the top answer of the question I linked?

Answer 1

I don't know whether it's possible to shorten the code you have provided (I doubt it but perhaps someone will know a way). However you could use \set tieWaitForNote = ##t to a good effect here. When it is set to ##t, each note with tie waits for the next occurrence of the same note and ties it with that. So your snippet could be rewritten like this:

\relative f' { \set tieWaitForNote = ##t f4~ c'~ <f c' f>2 }

which would result in the first f tying right to the half-note f, without the need for the second f in between.

You can play with it in a lilybin that I put together for that.
