This document defines some basic macros for that allow you to write music notes with the ABC-notation. To transform this into nicely rendered music notes an to play the music online as well, this plugin uses the JavaScript library abcjs. This plugin allows you to use ABC music in two ways, only for showing and playing, or to write and interpret ABC interactively with an editor.
Try it on LiaScript:
See the project on Github:

There are three ways to use this template. The easiest way is to use the
import statement and the url of the raw text-file of the master branch or any
other branch or version. But you can also copy the required functionality
directly into the header of your Markdown document, see therefor the
last slide. And of course, you could also clone this project
and change it, as you wish.

Use the render with option to change the default settings. A list of all possible parameters is defined in section Options. Additionally it is possible to set these parameters as comments within the ABC-code, as it is demonstrated here.

Next to just showing the notes, it is also possible to directly edit music with
the LiaScript editor. Alls states and versions will be preserved. Simply add the
@ABCJS.eval macro to the end of the code-block. This will run eval with the
default settings and print out the result within the console. The code-example
contains a list of all settings that can be changed by the user, this will
overwrite the default settings and gives you more control over your composition.

This is similar to the @ABCJS.renderWith version an allows you to configure
the output more precisely. Additionally it is also possible, to overwrite these
settings within the comments, as shown in the previous section.

@ABCJS.evalWith(autoplay="true" debug="true")
| option | Description |
|---|---|
audio |
Display audio settings, by default true. |
autoplay |
Start playing immediately when the site/abc becomes visible (by default disabled) |
channel |
The "midi channel" to use. This isn't particularly useful except that specifying channel 10 means to use the percussion sounds. |
debug |
Combinations of ABCJS showDebug: ['box', 'grid'] which shows some visual debug information. |
notes |
Depict the notes, by default this is enabled, set it to false to hide them and to display only the "playback". |
program |
A number for the midi program (aka "instrument") to use, if not specified in ABC string. |
responsive |
Used by default, if you set this to false, then there will be a scrollbar displayed on small screens. |
tablature |
Add tablature options as defined here. |
voicesOff |
If true, play the metronome and accompaniment; do the animation callbacks, but don't play any melody lines. |
chordsOff |
If true, then don't turn the guitar chord symbols into sound. (But do play the metronome if there is one.) |
stereo |
Use pan to mimic stereo sound (by default set to false). |
