Numbered musical notation and so on. Dashes after a note lengthen it, each dash by the length of a quarter note.

ABC notation ABC notation ABC notation is a shorthand form of musical notation. In basic form it uses the letters A through G to represent the given notes, with other elements used to place added value on these - sharp, flat, the length of the note, key, ornamentation.

In this later form it remains a language for notating music using the
