Music Grid Markdown

Write formatted music grids (chords and structures), with live preview.

The output are well formatted music grids, that you can view or print. Here is an example:

The input is a text file written in a special markdown syntax called "music grid markdown". Here is the script that produced the grid above:

# The Tune title
## A super cool subtitle
Author: The Author // the composer's name
Copyright: Relevant Copyright

// this is a line comment

- [INTRO]x2 "Drums play 8 bars".

- [A]x2 Play in a certain way.

4/4 [: {Tacet first} Dm | {1.} Dm  A7 :]{2.} Dm D7 |
| G | % | % | A7 Dm |

%vspace%

- [B]x2 Play in a certain way.

| Gm | (Break!) Dm - - - | === |
| {solo trumpet} -7- .l | A7 Dm |

- [A]x2 -> [B]x2 -> [CODA]

Install and use

MusicMarkdown is an executable python module.

Download and install Python3 (if it is not installed already in your system)
Install the module with this command in a terminal window
```
 pip3 install musicmarkdown
```
Create your music markdown script (or download the example one).
Use a terminal window to goto the folder that contains your script and run this command:
```
 python3 -m musicmd script.txt
```

This will generate an html file that you can open with your web browser. Then you can print it or save it as PDF etc.

If you want to open a live preview that changes as you edit the script, you have two options:

Maybe the easiest is to run this command in a terminal:

python3 -m musicmd script.txt serve

It will start a built-in web server and give you a link to open in a web browser. This will display the preview of the grid and show live modifications as you change (and save) your script. This option needs javascript enabled in your browser (which is usually the case, unless you disabled it on purpose)

Another option is to use an external preview, for example Atom's "Preview HTML" extension. This allows to have the script and the preview in the same editor. In this case run this command in a terminal:

python -m musicmd script.txt watch

and then open both your script and the generated html file and start a preview.
