Decrease paper size so there is less white space between the rendered image and the code

Metric modulation (proportional tempi)

Gabriel Ellsworth — Sat, 13 Jun 2026 22:38:39 GMT

I added links to Yoshiaki Onishi’s solution.

	This snippet shows how you can typeset a metric modulation as a rehearsal mark.

			'''Some other approaches to metric modulations:'''
			# [[Metric modulation with tuplet]] shows a way to indicate a metric modulation that refers to a duration within a tuplet.
			# Yoshiaki Onishi’s approaches use <code>\textEndMark</code> and <code>\textMark</code> and print left and right arrows (← →) on each side of the equation, following the example of the scores of composer Elliott Carter. For an explanation, search for “Metric Modulation Equation” in Onishi’s [https://github.com/yoshiakionishi/lilypond-snippets/blob/main/DOCUMENT/YO_SNIPPETS_COOKBOOK_MASTER.pdf LilyPond Contemporary Notation Cookbook]; for the code, see [https://github.com/yoshiakionishi/lilypond-snippets/blob/main/DOCUMENT/metricModulationRegularFlag.ly metricModulationRegularFlag.ly] and [https://github.com/yoshiakionishi/lilypond-snippets/blob/main/DOCUMENT/metricmodulationStraightFlag.ly metricmodulationStraightFlag.ly]. His commands support tuplet note values.

Talk:Displaying LilyPond's data directory

Gabriel Ellsworth — Fri, 12 Jun 2026 11:38:08 GMT

Gabriel Ellsworth moved page Talk:Displaying LilyPond's data directory to Talk:Displaying LilyPond’s data directory Misspelled title: I changed the tick mark in “LilyPond’s” to curly (typographical) punctuation (a real apostrophe).

New page

== No LilyPond tag on scheme code ==

I purposely did not use the <code><lilypond></code> tag on this code because I didn't want to expose the Wiki's internal structure. If I'm being overly paranoid we can add it later. [[User:Ksnortum|Ksnortum]] ([[User talk:Ksnortum|talk]]) 16:42, 18 February 2026 (UTC)

:Printing the path inside the wiki wouldn't be a problem, but you can't use <code><nowiki><lilypond></nowiki></code> because it doesn't support snippets which don't produce any visual output. I think giving an error in this case is the right default for <code><nowiki><lilypond></nowiki></code> because we want to remind editors that snippets should come with examples, but adding a <code>no-output</code> option to <code><nowiki><lilypond></nowiki></code> could be sensible.

Displaying LilyPond's data directory

Gabriel Ellsworth — Fri, 12 Jun 2026 11:38:08 GMT

Gabriel Ellsworth moved page Displaying LilyPond's data directory to Displaying LilyPond’s data directory Misspelled title: I changed the tick mark in “LilyPond’s” to curly (typographical) punctuation (a real apostrophe).

New page

In [[Frescobaldi]], you can install LilyPond while editing the Settings options. However, it is not always clear what directory LilyPond is installed in.

Using the following code will display LilyPond’s data directory in the LilyPond log.

<pre>
\version "2.24"

#(ly:message "The LilyPond data directory is located at: ~a" (ly:get-option 'datadir))
</pre>

(Thanks to Mark Knoop for this code.)
