Jean Abou Samra: Import snippet from LSR

Import snippet from LSR

New page

This code shows how to transpose a whole score by changing one single piece of code.

In the code the Scheme function <code>MyTranspose</code> is defined. If you use it in every <code>Voice</code>, you can transpose the whole score just by setting the arguments to the <code>\transpose</code> call within the function definition. As you see in the example this works with transposed voices as well (in the example I've written the Bb-Trumpet pitches as they sound, so they have to be additionaly transposed by <code>\transpose bes c' {...}</code>).

To see the original pitches, you may disable the <code>MyTranspose</code> function by redefining <code>MyTranspose = {}</code>, as shown in the lower part of the snippet.

%here starts the snippet:

global = {
\time 4/4
}

MyTranspose =
#(define-music-function (m)
(ly:music?)
#{ \transpose f d $m #})
% In the previous line the transposition of the whole score is defined
% (in this case from f major down to d major).
\markup "Transposed from F to D"

% To deactivate the transposition remove the comment sign from the
% following line:
%MyTranspose = {}

Basekey = {
\key f \major
}

FltPitches = \relative c'' { c d bes c }
TrpPitches = \relative c'' { c d bes c }

Flt = \new Voice {
\set Staff.instrumentName = #"Flute"
\MyTranspose { \Basekey \FltPitches }
}
Trp = \new Voice \transpose bes c' {
\set Staff.instrumentName = #"Trumpet"
\MyTranspose { \Basekey \TrpPitches }
}
\score {
\new StaffGroup {
<<
\new Staff { << \global \Flt >> }
\new Staff { << \global \Trp >> }
>> }
\layout {}
}

% End of the example
% =============================================================
% The remainder is just for visualisation the deactivation of the
% transposition in a single snippet. You don't need this code in
% normal use...

\markup "The same without transposition:"
MyTranspose = {}

% The remainder is just a copy of the corresponding lines above:
Flt = \new Voice {
\set Staff.instrumentName = #"Flute"
\MyTranspose { \Basekey \FltPitches }
}

Trp = \new Voice \transpose bes c' {
\set Staff.instrumentName = #"Trumpet"
\MyTranspose { \Basekey \TrpPitches }
}

\new StaffGroup <<
\new Staff << \global \Flt >>
\new Staff << \global \Trp >>
>>
