Hi all,

While Lilypond tends to do a very good job in most cases, there are two
issues which seem to be recurring a fair bit in the music I'm typesetting:
-beam angles being too steep
-beams crossing staff lines (which is a style choice, arguably, but usually
avoided by the better publisher out there)
-in a few rare cases, an angled beam starting or ending in a space (this is
generally frowned upon, cf. Gould, p. 17f)

Both of these can be arguably rather easily be fixed with manual overrides
(fyi, if necessary: the syntax is \once \override Beam.positions = #'(-3 .
-2.75) , numbers adjusted as needed); but of course that takes time, makes
for pretty unreadable code post facto, and is in fact one of the most
frequent and few things I have to fix manually, so if it were at all
possible to make beams shallower by default that would be a huge time saver.

I don't know enough about the internals to know where even to look at for
something like this (it is at least independent of notation font as far as
I can test out). If I may mention it, I've seen something similar discussed
regarding another open-source software here [
https://musescore.org/en/node/152276] (with reference to how one of the
other WYSIWYG options allows to set defaults for it, scroll down a bit).

As an example, here are the first few bars of the 1st violon part from KV
418:

\version "2.24.4"

\language "deutsch"

\score {

\new Staff {
\key a \major \time 2/2
\relative c'' {

h4 r r8 f16.[( h32] d8[) d-.] |
}
}

\new Staff {
\key a \major \time 2/2
\relative c'' {
r2^"Manual fix" r8 \once \override Beam.positions = #'(-3 . -2.75) cis16.[(
e32] a8[) a-.] |
a4 r r8 \once \override Beam.positions = #'(-2.25 . -2) e16.[( a32] cis8[)
cis-.] |
cis4 r r2 | r r8 \once \override Beam.positions = #'(-2.25 . -2) d,16.[(
fis32] h8[) h-.] |
h4 r r8 \once \override Beam.positions = #'(-1.25 . -1) f16.[( h32] d8[)
d-.] |
}
}
>>
}

You can of course compare with the old Breitkopf offering on IMSLP; the
more recent Neue Mozart Ausgabe is very similar to that and both match the
manual fixes I have applied:
