Re: Overwrite key signature with numbers
Thanks for your response Jean, So, the music notation system I am writing has assimetrical staves with only 4 lines, which means there is a blank space wider than the other two white spaces. For notes that fall into the wider blank space, I want a ledger line value of 2, but for the note that falls into the narrower blank space (G) I want a ledger line value of 1. From what you say, I believe you are worried about chords, am I right? In that case it would depend on whether the highest note is a G if it is above the staff or if the lowest is a G if it is below the staff.

Re: Overwrite key signature with numbers
Thank you again Valentin, this is extremely helpful for me. In fact, I have
been able to override other properties based on the solution you provided.
I'm slowly making progress.
However there is something I am stuck with, based on your response above:
> If an overriden property expects a number, can it be defined as
> a function that receives a grob and returns a number? Exactly.
In the example below, I am receiving the following error: Wrong type
argument in position 1 (expecting Stream_event): #f
I think I am not receiving a grob in this case. How could I move forward
with this? The use case is very simple, if the note is a G I want to return
a 1 and if not I want to return a 2.
\version "2.23.6"
#(define my-desperate-test
(lambda (grob)
(let ((note (ly:event-property (event-cause grob) 'pitch)))
2
)))
\layout {
\context {
\Staff
\override StaffSymbol.ledger-extra = #my-desperate-test
}
}

Re: Overwrite key signature with numbers
Oh David's right, if the music ends with no alterations it is printing the
key cancellation, even when it has been explicitely set to false.[image:

What can I do in this case? I would like to keep the number+alteration but
remove the 7 natural signs before that.
Thank you,

Re: Overwrite key signature with numbers
Thanks a lot Valentin, that's simply perfect!
However, after reading a lot of the documentation I think I would have
never been able to find any solution close to yours. I am very confused
with a few things, and I can't find the answers in the documentation. Let
me ask you a few questions in hope that I will be able to solve problems on
my own next time.
- How did you know you could pass a function that receives a grob to
KeySignature.key?
- If an overriden property expects a number, can it be defined as a
function that receives a grob and returns a number?
- How did you know alterations-alist is a property of that grob?
- What is #:vcenter and how did you know of its existence?
Thank you again,
Robert

Overwrite key signature with numbers
Hi, I am trying to overwrite the key signature for my custom music notation
so that instead of displaying the sharp and flat icons, it shows a given
number and the alteration. So, for example, E Major would show 4# instead
of .
I have been able to get the desired output by hardcodeing it using the
markup function. However, I am not finding a way to conditionally render
the number and alteration depending on the key. Could somebody help me?
Here is my tiny hardcoded example, with a screenshot:
[image: image.png]
\version "2.23.6"
\layout {
\context {
\Staff
\override KeySignature.stencil = #ly:text-interface::print
\override KeySignature.text = \markup {
\combine
\halign #-1 \lower #1 \musicglyph "four"
\halign #-5 \musicglyph "accidentals.sharp"
}
}
}
\relative {
\clef bass
\key e \major
cis dis e
}
RE: Stem.note-collision-threshold
Hi Jean, thanks for your reply.
Find attached a tiny example of what I am doing. As you will see, if the
interval is composed of 3 semitones (either C D# or C Eb) the noteheads are
positioned one of top of the other. However, when the interval is composed of 2
semitones they overlap.
I understand float numbers are tedious, but I don't think there is need for
much precision here. I mean, in my case even though I want 2/3 distance between
notes I could specify 0.7 and everything should work.

Comparing floats is hazardous due to decimal precision issues. On the
other hand, it might be possible to make it accept rational numbers like
#3/2.

Could you give a code example? It's not clear to me what different

RE: Position chromatic notes in 1/3 note head size instead of 1/2
Hello Valentin,
By increasing the distance between lines it fits, yes, but that is not how this
music notation was specified. They specify 1/3 notehead size vertical distance
between chromatic notes.
My staff, for example, is defined as follows:
\layout { \context {
\Staff
\override StaffSymbol.line-positions = #'(-5.67 -2.33 2.33 5.67)
}}
So no integer number in staffLineLayoutFunction will allow me to match my lines
with the noteheads. This is why I think it would make sense to allow passing
decimal numbers to staffLineLayoutFunction.
As an alternative, I tried setting manually NoteHead.Y-offset to decimals, but
then I have the problem that the note position should be different depending on
the clef...

Hello Robert,
mathematically 1/3 instead of 1/2 means 50% more, this 3*1.4 = 4.5 notes
should fit.
But the same thing should be doable by simply increasing the distance between
lines, like this:
<<
\new NoteNames { c d e f g a b c d e f g a }
\new Staff \with {
\override StaffSymbol.line-positions = #'(-6 -3 0 3 6)
} \relative c' {
c d e f g a b c d e f g a
}

RE: Position chromatic notes in 1/3 note head size instead of 1/2
Hello Valentin, thanks for the response. That's not really what I want, instead of defining a new Staff (which I already did btw) I want to position the notes so that more noteheads fit in the same height. For example, let's take the height starting from the e bar to the b bar in treble. In the traditional notation, only three noteheads fit between this height (f g a). In this new notation, 4 noteheads should fit because the vertical distance between notes is 1/3 instead of 1/2.

Position chromatic notes in 1/3 note head size instead of 1/2
Hello everyone,
I am trying to position the notes of my custom music notation as in the

I tried using a custom callback for staffLineLayoutFunction. I thought it was
going to be enough, but it won't allow decimal numbers.
Does anybody have any idea how I can implement this behaviour? Find attached a
Tiny.ly as well.

(This happens from time to time, and I’m not sure why this is so.) To get your callback working you can ensure that the font-size is calculated by doing something like \override NoteHead.stencil = #(lambda (grob) (ly:grob-property grob 'font-size) (ly:note-head::print grob)) (the grob-property effectively just forces Lilypond to calculate the value).

that allows me to move forward. I really hope you can help me.
Find attached a Tiny.ly, I did the same for changing things like NoteHead.text

cannot use the grob when changing the NoteHead.font-size
I would really appreciate any help. Am I doing something wrong? Is there a

Thanks in advance
