Hi,
I hope someone can point me in the right direction.
What I'd like to do is print multiple bar numbers for repeated sections.
The situation is that I have one instrument (upright bass) whose musical
figure repeats,
while other instruments have different material.
The bass player finds it difficult to turn pages, so to conserve space,
I notate their part with repeats, whereas everyone else has everything
written out.
I can get the overall bar numbers to coincide (after the repeat) by using
\set Score.currentBarNumber = #13
But in the repeated section, for the bass part,
only the first number prints (as expected).
Here is my MWE of what I have now:
\version "2.19.15"
% all parts but bass
\score {
\relative c'' {
c1 | 1 | 1 | 1 | \break
\bar "||"
cs1 | 1 | 1 | 1 | \break
ds1 | 1 | 1 | 1 | \break
\bar "||"
e1 | 1 | 1 | 1 |
}
}
% bass part
\score {
\relative c {
\clef bass
c1 | 1 | 1 | 1 | \break
% I'd like this measure to show both bar numbers "5" and "9"
% Perhaps by invoking a function like this:
% \double-bar-numbers 4
\repeat volta 2 {
\bar "[|:"
b1 | 1 | 1 | 1
\bar ":|]"
} \break
\set Score.currentBarNumber = #13
e1 | 1 | 1 | 1 |
}
}
My intention of the comment above,
\double-bar-numbers 4
is to specify the following logic:
"at this point, instead of using the default bar number markup function,
use this double-bar-numbers markup function, which takes an argument
for the number of repeated bars."
And then that function would do the following:
"Read the current bar number,
calculate a second bar number
by adding the current bar number to the supplied value
then print those two numbers in a column"
I'm basically unsure about every step here:
Is there such a thing as "the default measure number markup function"?
Can I specify another function to be used instead of the
default measure number markup function, and if so, how?
Can I invoke this new measure number markup function on an as-needed basis--
not replace the default measure number markup function, since I would use
that
everywhere other than the places I explicitly specify to use the new one?
Can I supply this function with a number-type argument?
Within my new measure number markup function, how can I access the current
measure number?
Within my new measure number markup function, how can I add numbers?
Within my new measure number markup function How can I turn a number into
markup?
Here is pseudocode, of what I thought the function might look like.
It doesn't work because, among other things,
* I don't know how to convert a number to a markup.
* I don't know how to override the default measure number markup function.
* The syntax of "let" is also confusing (I have to enclose everything
in another set of parens just to have scope where the variable is defined?)
#(define-markup-command (double-bar-numbers layout props barCount) (number?)
"Draw two bar numbers"
(interpret-markup layout props
(let repeatBarNumber (+ #currentBarNumber #barCount)
#{
<>^markup \center-column {
#currentBarNumber
#repeatbarNumber
}
#}
)
)
)
Any hints would be greatly appreciated.
Thanks,
Elaine Alt
