I tried it briefly, and I've seen its use demonstrated in the
documentation, but it seems to require an abundance of information for
each note, which I'm hoping to avoid.
What I'm trying to do is create a music function whereby one can input
certain starting values, like:
\makeinfinityseries #2 #7 #1 #13
Those values would be used to generate a pitch series; and then that pitch
series would be printed in the score.
I've got a working version where I specify those values at the top of the
file, e.g.:
firstNote = #2
secondNote = #7
octave = #1
modulus = #13
and those definitions are followed by the Scheme code, which ends with a
(make-music) thing that prints the music, without any \score block (or
which is assigned to an identifier that I call from within the \score
block).
The problem with that is I can only use one set of variables within the
score -- I can only print one such pitch series. Of course, I could add
another set of variables at the beginning, and process those separately,
but I think it would be easiest and most flexible if I could do something
like:
\score {
\makeinfinityseries #2 #7 #1 #13
\bar "|"
\makeinfinityseries #2 #9 #2 #13
\break
\makeinfinityseries #4 #5 #1 #13
}
...et cetera.
But I keep getting stuck with the (make-music) thing not printing music,
or the variables being "unbound" at the point where they're used, or
various other problems, and so I keep thinking there must be a simpler way
to print notes from Scheme.
If Lilypond can do:
{ c'4 d' e' }
Surely, I would hope, Scheme can do something simpler than:
(make-music
'SequentialMusic
'elements
(list (make-music
'EventChord
'elements
(list (make-music
'NoteEvent
'duration
(ly:make-duration 2 0 1 1)
'pitch
(ly:make-pitch 0 0 0
(make-music
'EventChord
'elements
(list (make-music
'NoteEvent
'duration
(ly:make-duration 2 0 1 1)
'pitch
(ly:make-pitch 0 1 0
(make-music
'EventChord
'elements
(list (make-music
'NoteEvent
'duration
(ly:make-duration 2 0 1 1)
'pitch
(ly:make-pitch 0 2 0))
or even:
(seq-music-list
(list (make-note (list (make-note-req (ly:make-pitch 1 0 0)
(ly:make-duration 2 0
(make-note (list (make-note-req (ly:make-pitch 1 1 0)
(ly:make-duration 2 0
(make-note (list (make-note-req (ly:make-pitch 1 2 0)
(ly:make-duration 2 0))
...especially as all I want, in this case, is pitches.
And because it's possible to manually type notes within a music function
in Scheme, e.g.:
function =
#(define-music-function (parser location var1) (integer?)
#{
c'4 d' e'
#})
It seems like it should also be possible to substitute variables for those
notes, such as:
#(define-music-function (parser location var1) (integer?)
#{
$firstnote #(list-ref notes 1) #(list-ref notes 2)
#})
From what I can tell, the key is the "ly:music" data type, but I don't
know how to to use that from within Scheme, if it's even possible, much
less how (if possible) to convert e.g. strings to ly:music.
The "ly:export" function may also have something to do with it, but if so,
I haven't figured out quite what.
Thanks for your help,
Marcus

Re: Setting line width from the command line?

Yes, but if I have a file with 21 songs of four parts each, that means
I have to change 83 lines every time I want to fiddle with the
margins. If there were a command line switch, I could change just the
geometry line and the command line in the makefile.
Does anyone know whether there's some other LaTeX syntax which would
define a macro or variable so that lilypond-book could use it in this
case?
Of course, if the bug where the lilypond lines are too long would just
get fixed, that would be easier still.

Why are variables received by #(define-music-function) unbound in #{ #(scheme code here?) #}
Either I've found a bug, or (more likely) I don't understand how variables
are passed between Lilypond and Scheme.
Below is an example, where a #(define-music-function...) block receives a
variable, stringone. That variable seems to be accessible (i.e. bound, if
I have my terminology straight) in two places, but not accesible (i.e.
unbound) in the third place.
1. Accesible by Scheme code within #(define-music-function) but outside of
#{ #} block
2. Accessible by Lilypond input within #{ #} block
3. Not accesible by Scheme code within #{ #} block
Why is this, and is there any way to pass a variable, received by
define-music-function, to Scheme code within the #{ #} block?
Thanks in advance,
Marcus
\version "2.9.23"
function = #(define-music-function
(parser location stringone)
(string?)
(let ((stringone (string-append stringone " foo")))
#{
% uncommenting the following line yields "ERROR: Unbound variable:
stringone"
%#(string-append stringone " bar")
c1^\markup { $stringone }
#}))
\relative c'' { \function #"one" }

about rightHandFinger
Hi:I just read that lilypond includes support for rightHandFinger events. Being a guitarist I was thrilled. I ran the example and tried a couple of experiments to see if I could change the capital P and I that appear, in guitar the fingers are spelt in lowercase p, i, m, a. \rightHandFinger #0 ... #11. 0 and greater than 5 appear as "x". Is there a way to tweak the way it displays the fingerings? -- Daniel Tonda C. ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
chordnames in parentheses?
