abc2mtex is a notation package that uses an ASCII input format. It was designed primarily for folk and traditional Western European music (such as Irish, English, and Scottish), which can be written on one stave in standard classical notation. However, it also supports multiple staves and can be used with many other types of music. It can also be used as a fast preprocessor for MusicTeX or MusiXTeX.
