-@section Goals for LilyPond
-
-GNU LilyPond was written with some considerations in mind:
-
-@itemize @bullet
-@item Describing a well-defined language for defining music. We call
- this language (rather arrogantly) The Musical Definition Language
- (mudela for short). GNU LilyPond reads a mudela sourcefile and outputs a
- TeX file.
-@item Providing an easy-to-use interface for typesetting music in
- its broadest sense. This interface should be intuitive from a musical
- point of view. By broadest sense we mean: it is designed for music
- printed left to right in staffs, using notes to designate rythm and
- pitch.
-@item Generating high-quality output. Ideally it should be of a professional
- quality. We'd like to render Herbert Chlapiks words, "Fine music
- setting is not possible without a knowledgeable printer," untrue.
-@item Making a system which is fully tweakable. It should be possible to
- typeset a book on how not to typeset music.
-@end itemize
-
-@node Development constraints, Goals for mudela, Goals for LilyPond, MANIFESTO - Rationale behind the GNU LilyPond project
-@section Development constraints
-
-Further considerations while doing the programming
-
-@itemize @bullet
-@item GNU LilyPond uses TeX for its output. This is not a key issue: in a
- future version, GNU LilyPond might bypass TeX, but at the moment TeX
- is convenient for producing output.
-@item GNU LilyPond does not display notes directly, nor will it be rehacked
- to be used interactively. GNU LilyPond writes output to a file. It
- will not be extended to play music, or to recognize music.
-@item GNU LilyPond is intended to run on Unix platforms, but it should
- be portable to any platform which can run TeX and the GNU tools
-@item GNU LilyPond is free. Commercial windows packages for setting music are
- abundant. Free musicprinting software is scarce. For more thoughts on
- this, please consult the @file{gnu-music} documentation.
-@item GNU LilyPond is written in GNU C++. It will not be downgraded/ported to fit
- broken systems.
-@end itemize
-
-@node Goals for mudela, Top, Development constraints, MANIFESTO - Rationale behind the GNU LilyPond project
-@section Goals for mudela
-
-The design of Mudela has been (perfect past tense, hopefully) an
-ongoing process, the most important criteria being:
-
-@itemize @bullet
-@item define the (musical) message of the composer as unambiguously as possible.
- This means that, given a piece Mudela, it should be possible for a
- program to play a reasonable interpretation of the piece.
-
- It also means that, given a piece of Mudela, it should be possible for a
- program to print a score of the piece.
-@item be intuitive, and easily readable (compared to, say, Musi*TeX input,
- or MIDI :-),
-@item be easily writable in ASCII with a simple texteditor
-@end itemize
-
-Other considerations were (and will be):
-
-@itemize @bullet
-@item be able to edit the layout without danger of changing the original
- music (Urtext),
-@item allow for adding different interpretations, again,
- without danger of changing the original,
-@item easy to create a conductor's score,
- as well as the scores for all individual instruments,
-@item provide simple musical manipulations, such as @emph{i} extracting a
- slice of music from a previously defined piece, @emph{ii} extracting
- only the rhythm from a piece of music, @emph{iii} transposing, etc.,
-@item easy to comprehend to both programmers and others.
-@end itemize
-
-One of the things that (might) be here would be: feasible to use in a
-graphic editor. We don't have experience with these beasts, so we
-don't know how to do this. Comments appreciated.
-
-Musical pieces could be
-
-@itemize @bullet
-@item Orchestral scores, (eg Mahler)
-@item piano pieces (eg. Schubert, Rachmaninov),
-@item pop songs (lyrics and chords),
-@item Gregorian chants,
-@item Bach multivoice organ pieces,
-@item Short excerpts to be used in musicological publications.
