Is that playable? I sadly haven’t touched my cello for a few months now 
and it’s 350 km away so I can’t try but I think I couldn’t play that 
passage despite having long fingers …


It's a transcription of the violin part of the violin+piano arrangement 
of Danse Macabre. For the violin, it's up an octave and the problem I 
have with it doesn't arise -- it's comes out much the same as tenor 
clef. Lots of it can't be reasonably written without treble clef, so 
being capable in that clef is necessary; the high note I think is a'' / 
A5 (the A just above the top of the treble staff)


The violin part has b flat in the lower voice, not g. That makes it 
playable on the cello too but brings me to the question how you’ll 
arrange the following measure …



 >      { s4^"The default, but melody 'lost' in the other visual
noise" }

Looks fine IMO.


I also got rid of some elaboration of why I thought this was a problem 
in the first place, which is that I find it difficult to see the line of 
the top notes there; to me, the inter-note intervals are kind of buried 
amidst a ton of stems and staff lines and such. In fact, that actually 
held one of just two typos I've found that made it through all my 
proofreading and to the point where I started to actually work from the 
part. But who knows... maybe I'm the odd one out here and most people 
*wouldn't* have any problem with it; maybe I'm too stuck up on the fact 
that I made a typo and am trying to overcorrect.


If it’s hard to read because of a “ton of stems and staff lines and 
such” maybe there is a layout problem, f. e. too small staff size, 
staves not far enough apart. Changing the stem direction shouldn’t be 
necessary.

vertical position of OttavaBracket

[Malte Meyn]

Hi list,

I’m currently working on a patch that would make the default ottavation 
texts/markups (currently "8va"/"15ma" and "8vb"/"15mb") changeable by 
the user without having to \set Staff.ottavation after each \ottava, see 
the following code and attached picture:


%
\version "2.21.0"
.
  %{
  \set Staff.ottavationMarkups =
  #`(( 2 . ,#{ \markup \concat \general-align #Y #UP { "16" \teeny "ma" 
} #})
 ( 1 . ,#{ \markup \concat \general-align #Y #UP { "8" \teeny "va" 
} #})

 (-1 . ,#{ \markup \concat { "8" \teeny "va bassa" } #})
 (-2 . ,#{ \markup \concat { "16" \teeny "ma bassa" } #}))
  %}
  c''4 4 4 4
  \ottava 1
  c'''4 4 4 4

  \ottava -1
  c'4 4 4 4
  \ottava -2
  c4 4 4 4
  \ottava 0
  c''4 4 4 4

The superscript/top-aligned "va"/"ma" that I’ve seen sometimes in sheet 
music doesn’t work well with the center-aligned OttavaBracket dashed 
line. How can this made be top- or bottom-aligned (or aligned depending 
according to the 'direction property)?

Important question: What instrument(s) will play this? Is this from a

Looks fine IMO.

This needs too much space on the lower side. IMO that departs too much.

     { s4^"This also works well but this is an area already with tons of

What instrument(s) is this for? Piano/harp/violin(s)/…: NO! They don’t 
know that clef. Bassoons/cello(s): Yes, use treble clef only if really 
necessary (in most cases); either this or the first solution is fine. 
Trombones: YES! AFAIK they don’t know treble clef.



   r4^"I don't like this but for completeness..."


Piano? → depends on whether this should be played with one (big) or two 
hands. Two instruments/divisi: Maybe better than the first solution. One 
or unisonon violins: the first solution is better.

Reformulating it as

So if magic doesn’t work, one can do it by hand:

So then I decided I would need a software-independent solution and tried 
OpenType magic. The result is a font that I can use in LilyPond, LaTeX, 
LibreOffice, and other programs that support OpenType features. The 
current state is only a proof of concept without proper documentation 
and without really knowing whether I’ve done the OpenType magic 
correctly. But it’s been good enough for my needs so far. You can find 
it at https://github.com/mmeyn/Riemann. For usage, have a look at 
http://notat.io/viewtopic.php?f=4=403.


I’d very much like to improve that solution and make it more 
feature-complete, better usable, and less hacky. But that would probably 
need some expertise on OpenType and fonts in general.

Re: Problem with merging whole measure rests

Hi David,

if I understand correctly you see a problem with the 
Merge_rests_engraver (your attached file from-NR.ly)?


That engraver didn’t merge MultiMeasureRests until 2.19.65 and does so 
since 2.19.80 (the first prerelease for 2.20.0, hence the version number 
jump from 65 to 80). However, merging of MultiMeasureRests gives them an 
incorrect vertical position in 2.19.80–2.19.83. The not yet released 
2.21.0 fixes this.


@someone who knows about such things: Would it make sense to cherry-pick 
that fix into the stable/2.20 branch?

You’ll need the two voices because of the opposite stem directions in

sets \voiceTwo internally instead of \voiceFour for the lower voice

It comes from the aes:m7.5- chord. LilyPond represents chords as pitches

Yup, this one fixes the warning and the weird rendering.
Still uses double-alterations (double-sharps) but that's a
separate issue (does lilypond have any support to automatically
simpmlify those notes and/or chords?).


Vanilla LilyPond doesn’t have such an automatism but I think there are 
functions for that in the LilyPond Snippet Repository. But after writing 
down my findings below I’d go for the harmonically correct sharps even 
in the untransposed version.





Though, tbh I doubt chords based on ees, aes, des _in_ a-major are
correct at all.
Probably some modulation/key-change before? Or copy from a weird source?


It's "The Shadow Of Your Smile" from the Real Book. I'm not sure
what's going on there, harmonically.


You seem to use the Bb version of The Real Book (vol. 1):
Eb-7b5 Ab7 Ab-7 Db7
The C version of The Real Book uses the harmonically more correct sharps:
C#-7b5 F#7 F#-7 B7
The Bb version of The New Real Book (vol. 3) uses the sharp version:
D#mi7(b5) G#7 G#mi7(b5) C#7

Note that you wrote a half diminished chord (m7b5) on Ab where the Real 
Book (at least the 5th edition) writes a minor 7 chord (m7).


If you have a close look at the melody in these measures (13–16) you’ll

The bigger problem is that while a-flat half-diminished is at least hard

LilyPond 2.18.2 did the most sane thing it could do and changed the 
b-tripleflat to a a-flat in that chord. You can see this if you output

You definitely should do that. Ideally by not using the single flat 
chords in the a major version in the first place … But if you really 
want to keep them, try transposing to d-sharp instead of e-flat.



but what strikes me is the "sus#4 b3" part, is it
a bug ? I'm using GNU LilyPond 2.18.2 and the
.ly file has a \version "2.18.2" header.


LilyPond 2.19.83 can handle triple flats (but cannot show them as notes

“r1” means a whole (=4/4) rest, not a whole measure rest.

The offending r1 is on the 3rd line of the first branch of the

Yes, “r2.” has the correct length. But you probably wanted to follow the 
engraving rule (as you should) and have a whole rest *symbol*. For that 
you have to tell LilyPond that it’s a *full measure* rest by using a 
capital R: “R2.” LilyPond will then use the correct symbol and center it 
horizontally.

It’s “half with dot” vs. “whole scaled by 3/4” even in the internal

\displayMusic {
  \time 3/4
  R2.
  R1*3/4

LilyPond’s Duration type makes this distinction, Moment doesn’t:

#(display (ly:duration-length #{ 2. #}))
#(display (ly:duration-length #{ 1*3/4 #}))
#(display (ly:duration-length #{ 4*3 #}))

For the output of MultiMeasureRests it doesn’t make a difference, for 
Rests and NoteHeads the choice of the duration affects the glyph choice.

The new default will be numbers only (#ottavation-numbers) with a simple

You’ll need two scores for both of the following solutions:

I've created a markup, simplified to 'X' in my example, and I would like to 
move it up partway into the staff.  I can move it down with a negative number 
but it won't move higher than '0' in \translate.  There must be a way to do 
this.


Yes, there is a way: You have to set outside-staff-priority and 
staff-padding to #'(). You can then use Y-offset instead of \translate 
to fine-tune the position.


You can either use [\once] \override or \tweak, the following works both 
for LilyPond 2.18.2 and 2.20.0:


{
  \once \override Score.MultiMeasureRestText.outside-staff-priority = #'()
  \once \override Score.MultiMeasureRestText.staff-padding = #'()
  \once \override Score.MultiMeasureRestText.Y-offset = -2
  R1_"X"

  R1-\tweak staff-padding #'() -\tweak outside-staff-priority #'() 
-\tweak Y-offset -2 _"X"

}
