3. required for being self contained, you can of course use any other
synthesizer you like better or a commercially one you've purchased but that's
all optional.
## Project Details
It's a complete pipeline to produce piano music. The first part is the format
of the sheet music/source code, just like you don't write a program in machine
instructions but in a high level programming language, you don't write a
piece of piano music in MIDI instructions but in a much more natural way similar
to how you would read a piece of piano sheet music, you can have a look at
the source code of [Brahms Op.79 No.2](#brahms-op79n2-src) to get the hang of it.
Then the source is compiled by the compiler, which is the second part, to produce
binary instructions/MIDI for the synthesizer, it handles expansions, event
ordering, accidentals, key signatures, dynamic tempos, to name a few.
The third and last part is the synthesizer producing sound samples from data
generated by the compiler, which could then be played directly or encoded
and saved.
It's not a program to just make sounds, or play some notes/chords, it's designed
from ground up to interpret the most difficult/complex piano music, and it's
proven, I have already interpreted twelve pieces of piano music, most of which are
non-trivial classical pieces, and can be viewed at ["youtube"](#youtube).
## Inch-stones
1. Split this project out into a stand alone git repository, rebase all
related commits and write meaningful commit messages.
2. Write detailed documentation, especially for the music source format.
3. Upload the first release to CPAN, with source demos for three piano
pieces.
4. Read MIDI specification throughly, I'm using a customized binary format
that's very similar to MIDI at the moment, but MIDI is inevitable since
it provides the freedom to use arbitrary synthesizer.
5. Implement MIDI output, and upload the second release to CPAN with
MIDI files of those three demos.
6. Depending on community feedback, implement most wanted features or
interpret more pieces.
## Project Schedule
This project will take six months, I can start working on it
after it's approved.
## Completeness Criteria
A release uploaded to CPAN with all deliverables accomplished.
## Bio
I'm creative and experienced in Perl, I created
[a new Linux distribution](#rslinux)
with Perl, I wrote [the first reference counting CPAN client](#app-rs), I invented
[a new object system for Perl with no code](#dot).
I played piano for three years, I've already received three copyright
infringement claims uploading piano music I programmed and synthesized with
this project to ["youtube"](#youtube), claiming that it's actually done by
some professional piano players.
