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
Grace note notes is always noted in terms of exactly half of its principal note, but may be double or more. Where they are multiple, their proper notation must always equal exactly half of the principal note. (i.e. If the principal note is a quarter-note the grace note must be notated as an eighth- note, two sixteenth notes, four thirty-second notes, or eight sixty-fourth notes, if we are to set aside the concept of unnatural subdivisions of the beat such as the triplet, etc.) Grace notes, unlike what are referred to as cue-notes, never affect the rhythmic subdivision, or musical "count" of
