[http://www.lilypond.org LilyPond] is a great music engraver, and you can include LilyPond in ConTeXt source using [httphttps://modulesgithub.contextgardencom/adityam/filter the filter module] with some setup.net/t-lilypond This is different from using the lilypond module-book preprocessor with LaTeX. (For LaTeX there’s also a package that works similar to our ConTeXt setup here: [https://github.com/jperon/lyluatex lyluatex].)

== Simple Filter Setup == This works with ConTeXt MkII and MkIV, but takes only the first page of multi-pages scores, and you must create the folder "lilytemp" manually:

\def\readPDFfile#1{\externalfigure[#1]} \usemodule[filter]\defineexternalfilter[lilypond] [continue=yes, readcommand=\readPDFfile, directory=lilytemp/, % directory for LilyPond's files output={\externalfilterbasefile.pdf}, filtercommand={lilypond-dbackend=eps -ddelete-intermediate-files -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]

==Multi Page Filter Setup = options ==={| style="border: solid 1px black; padding: 0.5em; vertical-align: top; width: 80%;" |- style="border: solid 1px black; padding: 0.5em; vertical-align: top; background: #eeeeee;"! option !! values !! default !! meaning|-| staffsize || number (pt) || 20 || height of the staff|-| time || yes/no || yes || count the time (i.e. show time signature, draw bars, split the staff)?|-| clef || yes/no || yes || show the clef?|-| align || yes/no || depends on fragment || ragged-right = (not align)|-| fragment || yes/no || no || typeset only a snippet (instead of a whole line)?|-| barnumbers || yes/no || no || show measure numbers?|-| seriffont || "name" || "Century Schoolbook L" || serif font (e.g. for Lyrics and \markup)|-| sansfont || "name" || "LMSans10" || sans serif font (e.g. for chords)|-| monofont || "name" || "Bitstream Vera Sans Mono" || monospace font (normally not used)|}

E.g. for == LilyPond Settings == Collect your LilyPond settings in a songbook you want to place big chunks of LilyPond output (i.e. note staffs) ly file, put it in your text. It behaves lilytemp directory and include it from within your lilypond block like any other graphics, especially similar to embedded [[MetaPost]] codethis:

\relative { \repeat volta 2 { \partial 4 e4 | a2 c4 d | e2 f4 e | d2. c4 | b4. c8 d4 e | a,2 c4 d | e2 f4 e | g,2 a | \partial 2. b2. | } \repeat volta 2 { \partial 4 r4 | f' g f d | e f e c | a b c d | e2include "mysettings. e4 | f g f8 e d4 |ly" e f e c | a c b8 a g4 | } \alternative { { \partial 2. g2. } { \partial 2. a2. } }}

There's nothing to say about this tune yet; my friend heard it from Lúnasa\defineexternalfilter[lilypond][ ... bufferbefore={lilypond::settings}, ...]

If you’d like to exchange measures like text width between ConTeXt and LilyPond depends on the fonts that pango/fontconfig can find. But not even all of , you could write those will work, e.g. no fonts from into the TeX tree LilyPond buffer (don't know whysee below), only one face per font file etc.Therefore it doesn't use ConTeXt's font setup.

If To give LilyPond measures to ConTeXt, you want would need to know which fonts of your system LilyPond can see with which names, try lilypond -dshow-available-fonts anywrite them into a temp file (using Scheme) and read that in again (using Lua).(The 3rd parameter For the time being this is necessary, but can be anythingleft as an exercise to the user.;)

Unfortunately you can’t define LilyPond’s text (lyrics) size with an absolute value, but only relative to staff size... == Named Buffers == Normally, your LilyPond's default text font is Century Schoolbooksnippets just get a running number. If you re-order your scores, each one gets re-rendered.  You can avoid that if you name your LilyPond snippets: just add <tt>[name=myfunnyname]</tt> to {{cmd|startlilypond}}. If you have just one LilyPond part per component (e.g. songs in a songbook), you could use <tt>[name=\currentcomponent]</tt>. == Automatical width adaption == If you want to set your note line width automatically to your current text width, try this:  -- this goes after "create temp folder" io.savedata("\LILYTEMP/texsettings.ly", "\\paper { line-width = " .. string.gsub(number.todimen(tex.dimen.textwidth),"pt","\\pt") .. " } \n") and then adapt your snippets or preamble buffer:<texcode>\include "../mysettings.ly"\include "texsettings.ly"</texcode> You must comment/delete the "line-width" setting in mysettings.ly, otherwise it doesn’t work. == Example == Here's an example of placing score snippets in ConTeXt like thisthe body of the text, with fonts in the score & body matching:
