Dear community,
I've got a problem with the changePitch function.
I expectedt to get the same rhythms in the first and second staff, but
it doesn't work. I don't understand, what could be the reason for this!
Hi, Stefan.
First of all, remember that changePitch is not one of the built-in
functions. Chances to get an answer are better if you attach or link to
the definition of the command, since also those can respond that did not
follow our last thread about it.
For your code: The time signatures and bar lengths in global do not
match, but that's a minor issue; nowhere in changePitch does it says
something about MultiMeasureRests. Factor those out into first and
second, and you probably get what you expected.
global = {
\time 4/8 s2
\time 3/8 s4.
\time 4/8 s2
\time 3/8 s4.
\time 4/8 s2
\time 3/8 s4.
}
goOn = { g'' 16 -. e'' ( fis'' ) gis'' -. g'' ( a'' ) | }
beginning = {
r4 r8 e'' 16 e'' | a'' 16 d'' fis'' fis'' r8 |
}
first = {
\beginning
R2 R4. R2 R4.
\goOn
}
second = {
\changePitch \beginning { cis'' cis'' f'' bes' es'' es'' s }
R2 R4. R2 R4.
\changePitch \goOn { b' c'' d'' es'' e'' f'' }
}
\score {
<<
\new Staff { \context Voice << {\first } { \global }>>}
\new Staff { \context Voice << {\second } { \global }>>}
>>
}
Why don't you try to keep stuff simple? Define an expression with the
rhythms, where you don't have to care about pitches, and define both
first in second in terms of those afterwards? Then you can easily factor
out the MultiMeasureRests, and the whole input is far less cluttered.
rhI = { r4 r8 c16 c | c c c c r8 } %% Pitches don't matter here -
to be used with \changePitch
rhII = { R2 R4. R2 R4. }
rhIII = { c''16-. c( c) c-. c( c) }
first = {
\changePitch \rhI ...
\rhII
\changePitch \rhIII ...
}
second = ... (similar)
Cheers,
Alexander
