JAM notation

{{Short description|Software and file format}}

JAM is both the software and file format for representing music as human-readable and human-writable text.

Unlike the ABC notation, another text-based music format, that is best suitable for one-voice tunes,

JAM is mainly focused on chords.

Here is an example of jam notation:
