@unnumbered Preface


It must have been during a rehearsal of the EJE (Eindhoven Youth
Orchestra), somewhere in 1995 that Jan, one of the cranked violists
told Han-Wen, one of the distorted French horn players, about the
grand new project he was working on.  It was an automated system for
printing music (to be precise, it was MPP, a preprocessor for
MusiXTeX).  As it happened, Han-Wen accidentally wanted to print out
some parts from a score, so he started looking at the software, and he
quickly got hooked.  It was decided that MPP was a dead end.  After
lots of philosophizing and heated email exchanges Han-Wen started
LilyPond in 1996.  This time, Jan got sucked into Han-Wen's new
project.

In some ways, developing a computer program is like learning to play
an instrument.  In the beginning, discovering how it works is fun, and
the things you cannot do are challenging.  After the initial excitement,
you have to practice and practice.  Scales and studies can be dull, and
if you are not motivated by others---teachers, conductors or
audience---it is very tempting to give up.  You continue, and gradually
playing becomes a part of your life.  Some days it comes naturally, and
it is wonderful, and on some days it just does not work, but you keep
playing, day after day.

Like making music, working on LilyPond can be dull work, and on
some days it feels like plodding through a morass of bugs.
Nevertheless, it has become a part of our life, and we keep doing it.
Probably the most important motivation is that our program actually
does something useful for people.  When we browse around the net we
find many people that use LilyPond, and produce impressive pieces of
sheet music.  Seeing that feels unreal, but in a very pleasant way.

Our users not only give us good vibes by using our program, many of
them also help us by giving suggestions and sending bug reports, so we
would like to thank all users that sent us bug reports, gave
suggestions or contributed in any other way to LilyPond.

Playing and printing music is more than nice analogy.  Programming
together is a lot of fun, and helping people is deeply satisfying, but
ultimately, working on LilyPond is a way to express our deep love for
music.  May it help you create lots of beautiful music!

@node Notes to version 2.2
@unnumberedsec Notes to version 3.0

The most important developments in 3.0 are related. In LilyPond 3.0,
@TeX{} is no longer strictly necessary to engrave music. This is
because LilyPond can now also layout pages and determine page breaks.
Another notable feature is the syntax, which has been simplified even
further compared to previous versions.
