Hello all,
For anyone who is interested in putting their 2ยข in on this
discussion...
Here is a simple instrument-doubling-with-key-signature-changes
challenge:
%%%%%%%%%%%%%%%%%%%%%
\version "2.11.49"
\include "english.ly"
#(set-global-staff-size 14)
\layout { \context { \Score printKeyCancellation = ##f } }
global =
{
\time 4/4 \key c \major s1*2 \bar "||"
\key c \minor s1*2 \bar "||"
\key d \major s1*4 \bar "||"
}
flute = \relative
{
c'4^\markup { flute (in C) } d e f | g1 | c,4 d ef f |
g1^\markup { alto flute (in F) } | d4 e fs g | a1 |
d,4^\markup { piccolo (in C') } e fs g | a1
}
\markup { C SCORE/PART }
\score { \new Staff = "fl" << \global \flute >> }
\markup { TRANSPOSED SCORE/PART }
\score { \new Staff = "fl" << \global \flute >> }
\markup { TRANSPOSED SCORE/PART SHOULD MATCH THE FOLLOWING: }
\score
{
\relative
{
\time 4/4 \key c \major c'4^\markup { flute (in C) } d e f | g1
\bar "||" \key c \minor c,4 d ef f |
\key f \minor c'1^\markup { alto flute (in F) } \bar "||" \key g
\major g4 a b c | d1 |
\key d \major d,,4^\markup { piccolo (in C') } e fs g | a1 \bar
"|."
}
}
%%%%%%%%%%%%%%%%%%%%%%
The goal is to make this (i.e., the transposed score/part) happen with:
1. a minimum of additional code;
2. a minimum of structural changes (e.g., if possible, we want
to keep the key changes in a single variable, not break up the flute
music variable, etc.);
3. a maximum of code reusability.
In other words, something that can easily be put in a template for
the average Lilypond user.
Good luck!
Kieren.
p.s. For the record, I haven't been able to find a way to use \tag
and \transpose together to solve the problem -- it always requires
code duplication or restructuring -- but my intuition currently says
that's the best approach...
