A super simple textual language, called ABCD, to represent music scores. This repository also comes with an music score editor for that language. The aim is to be natural to use like markdown for writing documents. The positions of the musical elements in the text is close to their real positions in the score. It makes easy to add instruments, change keys, add voices, add lyrics. Its main feature is rhythm inference: you do not need to tediously specify the duration of each note; the system tries to guess the most natural rhythm from the specification. The name ABCD is a hint to the abc notation.

The syntax is highly inspired from ABC and Lilypond.
| Feature | How to do it in ABCD |
|---|---|
| add treble clef | write π |
| add bass clef | write π’ |
| Notes and rests | write letters a, b, c, Add ' or , for changing the octavia |
| Accidentals | write #, β, ##, ββ |
| Rests Β Β | write r |
| Measures separationsΒ | write |, ||, |:, :|, :|:, |] |
| Rhythm | It is guessed from whitespaces, but you can mention with 2, 1, /, ., .., etc. |
| Uplets | Add (3 like in the ABC notation |
| Chords | put notes between [ and ] |
| Dynamics | !mp! etc. |
| Appoggiatura | put notes between { and } |
| add a new voice | just write in a new line |
| add a new staff | add an empty line or a line starting with π or π’ |
| Lyrics | start a line with π¬ or π |
| specify an instrument | start the line with the name of an instrument (e.g. piano, flute, violin, cello) |
| Change tempo | write β©=120 |
- real-time update of the score while modifying the code (like HedgeDoc for editing markdown)
- Listening to the audio (MIDI)
- Printing
- Loading/saving in the local storage of the browser
- Input from a MIDI device (in Chrome only)
- Export in MIDI and ABC
A file containing
π 2/4 e'2 | d' r
π’ r c | c/ c/ c
produces the score
In wysiwyg software, like Musescore, Finale, etc. you never know where to click.
The only thing to learn with a textual language is the language. Everyone knows how to use a text editor. Existing textual langages (like ABC and lilypond) are very expressive.
Existing languages are difficult to learn. The project aims at providing an easier to use textual language. Here are the main points:
- Both languages (ABC, Lilypond) have cryptic notations like
[K:bass]or\voice.... In particular, adding a voice, a staff or lyrics is a bit tricky in both languages, while it is obvious in ABCD. - Both in ABC and Lilypond, all the information concerning a single measure is spread out in the source.
Technically, this repository provides a program, that preprocesses an input in ABCD to produce an ABC string, and then produces the output with the library abc.js. Meanwhile it calls a solver for solving rhythm inference.
