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 or between the lines. The pitch of the oval musical noteheads can be modified by accidentals. The duration (note length) is shown with different note values, which can be indicated by the notehead being a stemless hollow oval (a whole note), a hollow rectangle (double whole note), a stemmed hollow oval (a half note), or solid oval using stems to indicate quarter notes and stems with added flags or beams to indicate smaller subdivisions, and additional symbols such as dots and ties which lengthen the duration of a note. Notation is read from left to right, which makes setting music
