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 note Do–Re–Mi–Fa–So–La–Ti are relativized and show only the relationship between pitches, where Do is the name of the base pitch of the scale, Re is the name of the second pitch, etc. The idea of so-called movable Do, originally suggested by John Curwen in the 19th century, was fully developed and involved into a whole educational system by Zoltán Kodály in the middle of the 20th century, which system is known as the Kodály method or Kodály concept. Musical note In music, a note is the pitch and duration of a sound, and also its representation in musical notation (♪, ♩).
