Metronome marks with more options
If you need, in metronome marks:
- change the default
=sign to other symbol, you can use the propertytempoEquationText. - change the default
-sign between tempo values (e.g. 100-120) to, say, 100~120, you can use the propertytempoBetweenText. - hide the default parenthesis in metronome marks, you can set the property
tempoHideParenthesisastrue. - 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.
Original snippet by Arnold Theresius
\version "2.24.0"
%%
% 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
