ChordPro

The ChordPro file format is a common format used in other software applications. OnSong understands this format natively. OnSong recognizes files with the following file extensions: .chordpro, .chopro, .cho, .crd, .pro

The ChordPro format allows for song information to be expressed in tags delineated by curly braces. This information can be logically divided into metadata tags and inline tags.

Metadata Tags

These are ChordPro tags that you would use in the metadata portion of the song. In the following tags, three dots (...) represent the text you supply, which goes between the colon and the closing curly brace. For example:

{title: Amazing Grace}
{key: G}

OnSong supports the following ChordPro tags:
