Generating pitches depending on key signature
Folks,
Assume I want a function that adds a second note a fifth a bove a given
pitch (of course this is but an abstraction from a more complicated
project).
The difficulty is that this should behave accoding to the key signature
in place. Hence, the fifth should not be always perfect but instead be
whatever occurs in the active key four note steps above the given pitch.
(Quite as in figured bass accompaniment.) Hence:
\version "2.19.80"
addFifth = #(define-music-function (pitch dur) (ly:pitch? ly:duration?)
(let*
((delta (+ 4 (ly:pitch-steps pitch)))
(new-pitch (ly:make-pitch 0 delta 0))
(pitches (list pitch new-pitch) )
(chordNotes (map (lambda (p) (make-music
'NoteEvent
'duration dur
'pitch p))
pitches))
)
#{
#(make-music 'EventChord 'elements chordNotes)
#}
)
)
{
\addFifth c' 1 % should yield -> ok
\addFifth cis' 1 % should yield -> ok
\key a \major
\addFifth c' 1 % should yield -> NOT OK
\addFifth cis' 1 % should yield -> NOT OK
}
I expect that this amounts to taking the alteration of my new-pitch from
the alteration-alist that is "active". But from what I can gather from
old postings on -user, this information seems not to be available at the
time a music function is called (correct?). What would be the way to go
for this?

Lukas,
A snippet to create octaves. Perhaps you could modify.

Re: Generating pitches depending on key signature
Mark, A snippet to create octaves. Perhaps you could modify. http://lsr.di.unimi.it/LSR/Item?id=445 Thanks much for the pointer! This definitely helps me understand how to write something like that and integrate it with Lilypond. I'm afraid, though, that this example does not tackle the aspect which is most difficult for me: The snippet makes perfect octaves, which is comparatively easy since you can copy a given pitch's alteration. I want neither that nor un-altered notes, but the alteration should be taken from the default alteration for this diatonic pitch class in the current key. Which I do not know how to access.

An unusual feature request concerning FiguredBass
Dear all, I am asked to add to psalm-setting two different figured bass lines, separated by a line and with, at the beginning of the first bar, the words "Pretonal" and "Tonal", as can be seen in the screenshot: Entering FiguredBass1 and FiguredBass2 did not give me anything but error messages, as expected Has any of you done or seen this double BC line? Thanks in advance for any advice or suggestion. Best regards, Robert Blackstone ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
Re: An unusual feature request concerning FiguredBass
Dear Robert,
I don't know this notation. So my advice is probably not the best solution.
> Entering FiguredBass1 and FiguredBass2 did not give me anything but
> error messages
You mean \new FiguredBass1 ? You cannot just invent context names. But
you can stack several contexts of the same type.
Here is one example that at least comes close:
\version "2.19.80"
<<
\new Staff
{
\clef bass
\key d \minor
\time 4/2
d1 2 a bes1 f a2 d a,1
}
\new FiguredBass
\with { \override BassFigure.extra-offset = #'(0 . -3.5) }
\figuremode { s1 s <5>2 <6> <6>1 s <_+> }
\new RhythmicStaff
\new FiguredBass
\figuremode { s1 s2 s <6> s2 s1 s s }
>>
\layout {
\context {
\RhythmicStaff
instrumentName = \markup \right-column {
"Pretonal" "Tonal"
}
\omit BarLine
\omit TimeSignature
}
}
Of course, the following would be much simpler and you could try to draw
a line by hand (\markup or so):
<<
\new Staff {
\clef bass
\key d \minor
\time 4/2
d1 2 a bes1 f a2 d a,1
}
\new FiguredBass \figuremode { s1 s <5 6>2 <6> <6>1 s <_+> }
>>
Cheers,
Joram

Re: An unusual feature request concerning FiguredBass
Robert,
it's easier to help you if you provide a Minimal Working Example,
otherwise it's hard to know what exactly you tried.
Anyway: It's not problem at all to create multiple
FiguredBass-environments. The line between them is a bit more tricky; I
once used a rhythm staff with all bar lines removed for this. For example:
\version "2.19.80"
<<
\new StaffGroup <<
\new Staff \relative f' { 1 }
\new Staff \with {
\override VerticalAxisGroup.staff-staff-spacing.basic-distance = 5
}
{ \clef bass f1 c }
>>
\new FiguredBass \with {
\override VerticalAxisGroup.nonstaff-unrelatedstaff-spacing =
#'((basic-distance . 0)
(minimum-distance . 0)
(padding . 0.5)
(stretchability . 0))
}
\figuremode {
<5>2 <6> <6>1
}
\new RhythmicStaff \with {
\omit TimeSignature
\omit BarLine
} {
s1*2
}
\new FiguredBass \with {
\override VerticalAxisGroup.nonstaff-relatedstaff-spacing =
#'((basic-distance . 0)
(minimum-distance . 0)
(padding . 0.5)
(stretchability . 0))
} \figuremode {
<6>1 <6>
}
>>
Unfortunately there remains a line connecting the RhythmicStaff to the
rest of the system; there is a way to remove this, but I do not have
time to look it up at the moment, I'm sorry.

Ideally you want to do as much as you can within LilyPond of course, but at least a small Inkscape delete is an option if all else fails you. :) ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
ossia
I want to set an ossia passage like the one in the attachment. I have achieved
partial success with the code below. The actual musical content in the code is
from the docs which I've attempted to modify to get my intended result. I have
managed to get the measure number on the main staff but not remove it from the
ossia staff, nor have I gotten rid of the left bar line or the first bit of the
ossia staff. I'd also like to add the "ossia" indication as in the image.
Thanks,
David

Re: An unusual feature request concerning FiguredBass
Ahem, If you want to get rid of the "connecting line", it might helpful to know that this line is called SystemStartBar and it lives in the Score context. So, \omit Score.SystemStartBar will make it disappear without SVG manipulation.

Making TextLength ignore some notes.
\version "2.19.81"
<<
\new Dynamics {
s2 s2^\markup \column {"I would very much" "like this to take" "up
precisely a" "minim's width."} | s1*2 | }
\new Staff {
b'2~ b'4\fermata a'4 \fermata | g'1~ | g'1 | }
>>
In the above example, I would like the words to occupy the horizontal
space between the 3rd beat of the first bar and the following barline.
In other words, the barline (and, hopefully) the final crotchet of the
first bar need to be moved suitable distances to the right.
\textLengthOn would be fine if the music underneath the text consisted
of only a minim, but of course it moves the crotchet on the 4th beat
past the end of the right-hand end of the text.
Is there any way of getting the effect I want, with the barline placed
after the text and the 4th-beat note placed evenly between the 3rd-beat
note and the barline?

\magnifyStaff alters thickness of barlines
Hi all,
I'm creating an organ part where the right-hand staff is supposed to be
slightly narrower than the left-hand staff. When I use \magnifyStaff to
achieve this effect, it also alters the thickness of the final barlines so
they don't match up:
\version "2.19.65"
\score {
\new PianoStaff <<
\new Staff = "right" \relative c'' {\magnifyStaff #6/7 a4 a a a \bar "|."}
\new Staff = "left" \relative c {\clef bass a4 a a a \bar "|."}
>>
}
Is there anything that can be done about this, or am I doing something
wrong? I would appreciate any advice.
Kind regards,
Brent.
