Beschreibung
If you need, in metronome marks:
- change the default = sign to other symbol, you can use the property tempoEquationText.
- change the default - sign between tempo values (e.g. 100-120) to, say, 100~120, you can use the property tempoBetweenText.
- hide the default parenthesis in metronome marks, you can set the property tempoHideParenthesis as true.
- change the color of the tempo value, you can use the property tempoNumberColor.
This snippet also changes the size of metronome marks:
- the text (e.g., Allegro) is a bit larger than the default of Lilypond.
- the note (e.g., ♪) is a bit smaller than the default of Lilypond.
IMPORTANT: This snippet is based on a snippet by Arnold Theresius. The original snippet create a formatter called format-metronome-markup-approx, and the default value to tempoEquationText in that snippet is "≈". I changed back this default to Lilypond default, and added the tempoBetweenText property. Also, I changed the sizing of some elements, as described above. http://lsr.di.unimi.it/LSR/Item?id=869

% Metronome markup formatter, with more options than the Lilypond
% default formatter, and changes in sizing (see below).
% Properties read:
% - tempoEquationText: text to be put between note and tempo value(s)
% Default: "="
% - tempoBetweenText: text to be put between the tempo values. Used
% only in ranges of tempo values.
% Default: "-"
% - tempoHideParenthesis: boolean. If true, the parenthesis are hide.
% Default: false.
% - tempoNumberColor: color. If set, the tempo value will be formatted
% to this color.
% Default: not set.
% The size of the text ("Allegro" etc) is a bit larger than Lilypond default.
% Similarly, the size of the note is smaller than Lilypond default.
%
% To use this snippet, just \include this file. To revert default
% Lilypond formatter inside the score:
% \set Score.metronomeMarkFormatter = #format-metronome-markup
