Numbered musical notation and so on. Dashes after a note lengthen it, each dash by the length of a quarter note. A dot after the plain or underlined note works increases its length by half, and two dots by three quarters. The underline, along with its joining, are analogous to the number of flags and beaming in standard notation. So are dotted notes. But the analogue stops at notes worth three quarter notes and beyond, where dashes are used instead. The number "0" represents the musical rest. The rules for length is similar to that of the note, except that it is customary
Musical notation notation. To a degree Braille music resembles musical markup languages such as MusicXML or NIFF. In integer notation, or the integer model of pitch, all pitch classes and intervals between pitch classes are designated using the numbers 0 through 11. The standard form of rap notation is the "flow diagram", where rappers line up their lyrics underneath "beat numbers". Hip-hop scholars also make use of the same flow diagrams that rappers use: the books "How to Rap" and "How to Rap 2" extensively use the diagrams to explain rap's triplets, flams, rests, rhyme schemes, runs of rhyme, and breaking rhyme
