Thanks everyone! tisimst, I slightly modified your solution and it seems to work great - thanks! For reasons I don't understand, it only changed the first StemTremolo in my score, but when I changed 'after-line-breaking' to 'before-line-breaking' it changed all of them. -- View this message in context: http://lilypond.1069038.n5.nabble.com/How-to-adjust-the-padding-between-a-StemTremolo-and-a-NoteHead-tp179448p179494.html Sent from the User mailing list archive at Nabble.com. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Sorry, the % is going to cause an error because it isn't a scheme
comment. Either change the "%" to a semicolon ";" or just remove my

Looking into the situation, I've found that there isn't a built-in
collision avoidance value but rather a well-tuned set of spacing
parameters (unless an actual beam exists, then collisions are taken care
of). It's quite easy to have the tremolo flags of unbeamed stems cause
collisions with the notehead:
\override Voice.StemTremolo.length-fraction = #1.5
Here's another option that works nicely by adjusting the value for "pad":
\layout {
\override Voice.StemTremolo.after-line-breaking =
#(lambda (grob)
(let* ((*pad 1.0*) % <--- ADJUST THIS TO TASTE
(cnt (ly:grob-property grob 'flag-count))
(stem (ly:grob-object grob 'stem))
(leng (ly:grob-property stem 'length)))
(if (> cnt 2)
(ly:grob-set-property! stem 'length (+ leng pad)
}

Here is that override approach with a duration condition:

)
(+ (ly:stem::calc-length stem-grob)

(stem-stretch stem-tremolo-grob) 0

I didn’t really like the idea of having to use a music function to do that … And of course it’s nice to modify the grobs instead of having to go through But unfortunately it doesn’t work properly in 2.19.24 (and 2.18.2): The stem lengths/tremolo positions are corrected but the stems themselves disapper :o And it breaks when there are stems on beams. (My solution would do this too if used on eigths, but it stretches only half and quarter note stems; eigths with flags are no problem because of the different slant of the tremolo beams.) ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

I made a scheme function from this that extends stems of quarter and
half notes if they have a tremolo of 32nd or shorter notes (see
attachment). Because I don’t know scheme well this looks like sort of
spaghetti code to me and might break soon; sorry for that, maybe it
could be improved.

Well, most such reservations should be addressable by putting a
container around, in this case
hoist = % for moving StemTremolo beams further from notehead
{
\once \override Stem.length =
#(ly:make-unpure-pure-container
(lambda (grob) (+ 1 (ly:stem::calc-length grob
}

How to adjust the padding between a StemTremolo and a NoteHead?
Hi all,
Consider the following tiny example:
/\version "2.19.23"
\relative c' { \time 6/4 4 q:8 q:16 q:32 q:64 q:128 }/
and its output:
<http://lilypond.1069038.n5.nabble.com/file/n179448/StemTremolo.png>
With one slash or two slashes, everything looks fine, but with three or more
slashes, the gap between the top of the NoteHead and the bottom of the
StemTremolo (illustrated with red lines in my image) is too narrow for my
liking. There is clearly some kind of minimum distance that Lilypond is
obeying, but I can't figure out what it is or how to adjust it. I have
looked through the Internals reference and played around with several
properties but without finding a universal solution. Is it a property of the
NoteHead, the Stem, or the StemTremolo?
At the moment I have to laboriously override the Stem.length-fraction on an
individual basis, depending on how many slashes there are, which is not
ideal.
Any ideas?
Thanks,
Dominic
