A major second or whole tone is one of three commonly occurring musical intervals that span two diatonic scale degrees; the others being the minor second, which is one semitone smaller, and the augmented second, which is one semitone larger. The major second is abbreviated as M2 and its inversion is the minor seventh. It occurs naturally between the 1st and 2nd degrees of a major scale, as the tonic rising melodically to the supertonic (the familiar Do-Re sung in moveable-do solfege).
