Mascii is a robust musical notation system that lets you easily input music using plain ASCII text from any standard computer keyboard, and is designed to be easily understood by humans and computers alike. The design goals for mascii were that it should be compact, chromatic, polyphonic, rhythmically expressive, and generally expressive, in that any combination of pitches and rhythms that can be notated in standard western music notation should be writable in mascii too.
