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
Numbered musical notation below a musical note raise or lower it to other octaves. The number of dots equals the number of octaves. For example, "" is an octave lower than "6". Musical scales can thus be written as follows: Where there is more than one dot above or below the number, the dots are vertically stacked. Where there are note length lines (see following section) underneath the numbers, any dots are placed below the lines. Thus the dots below numbers do not always vertically align with each other, since some of them may be moved slightly downward so as not to collide
