3 LilyPond - a music typesetter
7 lilypond [options] [inputfiles]
11 LilyPond typesets music. It translates script files (mudela files or
12 F<*.ly>'s) into TeX input. Typesetting music is a complex task,
13 whereas the message that printed music conveys is usually a simple
14 one. LilyPond is a try at providing a simple interface for setting
15 music. LilyPond has these features:
21 ASCII script input, with identifiers (for music reuse),
22 customizable notenames, customizable fontset
25 MIDI output lets you check if you have entered the correct notes.
28 Multiple staffs in one score. Each staff can have a different meters.
31 multiple stafftypes (melodic, rhythmic) [broken from pl28 on]
34 beams, slurs, chords, super/subscripts (accents and text),
35 triplets, general n-plet (triplet, quadruplets, etc.), lyrics
38 multiple voices within one staff; beams optionally shared
39 between voices. (well, more than 2 voices won't look pretty --yet.)
42 multiple scores within one input file. Each score is output to
46 clef changes, meter changes, cadenza-mode, key changes, repeat bars
50 =head1 DESIGN CONSIDERATIONS
52 LilyPond was written with some considerations in mind:
57 Describing a well-defined language for defining music. We call
58 this language (rather arrogantly) The Musical Definition Language
59 (mudela for short). LilyPond reads a mudela sourcefile and outputs a
60 TeX file. This musical definition language should:
65 define the musical message of the writer as unambigiously as
69 be easily readable. (as compared to, say, MusixTeX input)
72 be writable in ASCII (with a simple texteditor).
76 At this time, the language isn't yet defined precisely. It is evolving as
77 LilyPond is getting more complex.
80 We want to provide an easy-to-use interface for typesetting music in
81 its broadest sense. This interface should be intuitive from a musical
82 point of view. By broadest sense we mean: it is designed for music
83 printed left to right in staffs, using notes to designate rythm and
87 LilyPond uses MusiXTeX fonts and TeX for its output. This is not a key
88 issue: in a future version, LilyPond might bypass TeX, but at the moment
89 TeX is very convenient for producing output.
92 Generate high-quality output. Ideally it should be of a professional
93 quality. We'd like to render Herbert Chlapiks words, "Fine music
94 setting is not possible without a knowledgeable printer," untrue.
97 LilyPond does not display notes directly, nor will it be rehacked to be
98 used interactively. LilyPond writes output to a file. It will not be
99 extended to play music, or to recognize music.
102 LilyPond is intended to run on Unix platforms, but it should
103 be portable to any platform which can run TeX and the GNU tools
106 LilyPond is free. Commercial windows packages for setting music are
107 abundant. Free musicprinting software is scarce.
110 LilyPond is written in GNU C++. It will not be downgraded/ported to fit
119 =item B<-I,--include>=F<FILE>,
121 add F<FILE> to the search path for input files.
130 Turn debugging info. LilyPond will read the file F<.dstreamrc>, which
131 tells for what functions and classes may produce copious debugging
134 =item B<-w,--warranty>,
136 Show the warranty with which LilyPond comes. (It comes with B<NO WARRANTY>!)

144 Show a summary of usage

161 LilyPond may be freely distributed. For further information consult

166 For compilation you need.
171 Unix. LilyPond is known to run on Linux, AIX, Digital Unix and
172 Solaris (if you have the Cygnus WIN32 port of the GNU utils, it will
173 even work in Lose NT/95)
176 GNU C++ v2.7 or better, with libg++ installed. Version 2.7.2
177 or better recommended. I doubt if it will compile with AT&T CC.
183 Flex (2.5.1 or better)
189 The "Flower" library, which should be available from the same
190 source you got this from. The version of flower lib should match the
191 one which is found in the F<configure> script.
194 Perl. The Makefile uses Perl for trivial operations, and you
195 could tinker with it to use sed or awk.
199 LilyPond does use a lot of resources. For operation you need the following:
204 a fast computer (a full page of music typically takes 1 minute
205 on my 486/66, using the DEBUG compile. It's lot slower than most
206 MusiXTeX preprocessors)
212 The MusixTeX fonts. (I use version those found in MusixTeX
221 tar zxf flower-1.11.9.tar.gz
222 tar zxf lilypond-1.2.13.tar.gz
227 You might want to edit Variables.make to tailor the compilation flags.
228 why G++ >= 2.7? LilyPond & FlowerLib uses:
239 operator <?, operator >?
245 class Rational (libg++)

310 Check out the input files, some of them have comments
315 If LilyPond bombs out, then please recompile using with debugging info
316 turned on, and send a copy of the input which causes the error and a
317 gdb stacktrace of the crash. It also helps if you can print the values
318 of the objects. So if your trace is
321 #0 Interval::operator+= (this=0x11fffec60..)
322 at ../flower/interval.hh:50
323 #1 0x12005195c in Item::width (this=0x14008a680) at src/item.cc:39
324 #2 0x12008fdbc in itemlist_width (its=0x11fffed58 ..
328 Than it would help if you send a dump of the Interval and the Item
329 (use: C<print *this> or use LilyPond C<print()> methods).
331 This is a beta version of LilyPond. Please send your helpful comments
332 and patches to me (see AUTHORS section)
334 LilyPond is updated very frequently, the latest version is always available at:
335 ftp://pcnov095.win.tue.nl/pub/lilypond.
343 The initialisation file with symbol tables etc. It
344 includes files from the directory F<init/>.
350 There are some documentation files in the subdirectory F<Documentation/>,
351 among others: lilygut, lilyinput, error, faq,
355 LilyPond has no connection with the music package RoseGarden, other
356 than the names being similar :-)

362 LilyPond's roots lie in MPP, a preprocessor to the rather arcane
363 MusiXTeX macro package for TeX. A friend of mine, Jan Nieuwenhuizen
364 wrote the first 44 versions (0.01 to 0.44), then his program caught my
365 attention, and I was slowly sucked in to the interesting problem of
366 easily producing beautifully printed music. I contributed some
367 code. We soon realised that MPP's design was too fundamentally broken
368 to be repaired. It was decided to rewrite MPP. We debated a lot about
369 the requirements to an inputformat (fall 1995). I sat down and started
370 with a parser-first, bottom-up rewrite called mpp95 (which totally
373 After long and hard thinking, I came up with an algorithm for the
374 horizontal spacing of multiple staffs (april 1996) I coded it (and did
375 not test it). After starting with this fundamental piece, I slowly
376 added the stages which come before spacing, and after. A half year
377 later later, I had a first working version, (october 1996). I
378 announced Patchlevel 0.0.7 (or 8) to the mutex list after asking some
379 technical details on spacing; it was downloaded approximately 4 times.
380 Then I got the hang of it, and in the subsequent two months, I coded
381 until it had doubled in size (pl 23).
