js-leadsheet

This is a formatter for simple lead sheets, and it currently supports creation of chord boxes and annotation of changes over lyrics, as well as simple instrumental chord sequences. It does what I need it to at the moment...

It's written as a node.js bin module for command line usage, but you can also import leadsheet.js directly to use client-side.

The concept was inspired by Markdown.

Examples

The following

Title: My Song  
Artist: Me  

+ Cref x,3,2,0,1,0 C  

Verse 1=  
This is my [Cref]song  
It's not too [Dref]long

Chorus =  
So hear my [Eref]song  
And now it's [Cref]gone
