Hey all,
For class the other day, I had to typeset a Debussy example, and I found that
Lilypond does not like some of the hairier passages in Debussy. To wit:
<snip>
\version "2.13.46"
tuptrans = { \override TupletBracket #'transparent = ##t
\override TupletNumber #'transparent = ##t
}
arps = \relative c, {
\key aes \major
\override TimeSignature #'stencil = ##f
\time 3/4
\tuptrans
\times 4/5 {
\stemUp
\once \override Voice . NoteHead #'duration-log = 1
aes16 [ ( \set fontSize = #-3 ees'32 ] b'64 \change Staff = "up" \stemDown c
ees aes c \change Staff = "down" \stemUp ees f ees
\change Staff = "up" \stemDown c aes ees c \change Staff = "down" \stemUp bes [
ees, ) ] }
\times 16/22 {
aes,16. [ ( ees'32 ] b'64 \change Staff = "up" \stemDown c ees aes c \change
Staff = "down" \stemUp ees f ees
\change Staff = "up" \stemDown c aes ees c \change Staff = "down" \stemUp bes [
ees, ) ] }
<< {
\times 2/5 { \stemUp
\set fontSize = #0 c16 [ ( \set fontSize = #-3 g' e' \change Staff = "up"
\stemDown \clef treble g c d e g c ) ] r } } \\
{\tuptrans
\times 2/5 { s16 s s s s s s s \change Staff = "up" \stemUp \set fontSize =
#-3 c16 s } }

\times 16/20 {
\change Staff = "down"
\stemUp
\set fontSize = #0
\once \override Voice . NoteHead #'duration-log = 1
des,,,16 [ ( \set fontSize = #-3 aes'32 ] e'64 \change Staff = "up" \stemDown
\clef bass f aes des ees! \change Staff = "down" \stemUp \clef treble aes des

\times 16/17 {

\clef bass aes,64 [ ( e'64 \change Staff = "up" \clef bass \stemDown f aes des
ees! \change Staff = "down" \stemUp \clef treble aes des ees des aes
\change Staff = "up" \stemDown ees des aes f \change Staff = "down" \stemUp
\clef bass e aes, ) ] }
s4 |
}
bass = \relative c, {
\once \override TextScript #'self-alignment-X = #RIGHT
\stemDown
aes2 \stemDown c8 \stemDown bes
\change Staff = "down" \set fontSize = #0
\stemDown des2 ees,4
}
\score {
\new PianoStaff <<
\new Staff = "up" { \key aes \major \clef bass s2. s2 r4 }
\new Staff = "down" { \clef bass << \arps \\ \bass >> }
>>
}
</snip>
You'll see several questionable things in Lilypond's standard output, including:
1. Beam / staff collisions.
2. 64th note beams that seem too thick for the music they contain.
3. Slur / staff collisions.
4. Slur / clef collisions.
5. Slurs that reach down too far, which causes a large hump @ the top.
Usually, in this style, the slur tips are far away from the bookend notes in
the arpeggio, allowing slurs to be flatter at their apogees.
Before I start meddling with the source, are there workarounds to deal with
these 5 issues?
Cheers,
MS
