Editing Numbered musical notation (section)

===Note length===
The plain number represents a [[quarter note]] (crotchet). Each underline halves the note length: One represents an [[eighth note]] (quaver), two represent a [[sixteenth note]] (semiquaver), and so on. Dashes after a note lengthen it, each dash by the length of a quarter note.

A [[dotted note|dot]] after the plain or underlined note works increases its length by half, and [[double-dotted note|two dots]] by three quarters.

The underline, along with its joining, are analogous to the number of flags and beaming in [[musical notation|standard notation]]. So are dotted notes.
