Hi folks,
The contemporary glissando example
<https://lilypond.org/doc/v2.27/Documentation/notation/expressive-marks-as-lines#index-contemporary-glissando> shows
a technique of using a hidden cadenza note as a glissando endpoint and
an example where the glissando finishes out a measure. Unfortunately the
measure is extended to fit the hidden note, so there's some unexpected
blank space.
Another way to achieve this is with a hidden grace note endpoint, which
I learned from this section
<https://lilypond.org/doc/v2.27/Documentation/notation/expressive-marks-as-lines#Extending-glissandi-across-repeats>.
I believe this approach has the advantage of disturbing the horizontal
space less (or not at all?) but has the disadvantage of not working if
the fall-off is on the last note of the piece and the disadvantage (or
advantage?) of extending the glissando slightly into the next bar when
it's on the last beat.
I just used it in a score to notate a slow whole-note fall-off:
a1\glissando | \once \hideNotes \grace c,, r2 r8 g''(\f a[ b])
Would the hidden grace note technique be preferable in enough cases that
it should be documented in simple form alongside the cadenza technique
under "contemporary glissando"? Or is there perhaps an even better
technique out there for a "fall-off" style glissando?
Best,
Jakob
