A or '''whole tone''' is one of three commonly occurring
Musical Interval s 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 and most memorably between the 1st and 2nd degrees of a
Major Scale , as the
Tonic rising melodically to the
Supertonic (the familiar '''Do-Re''' sung in
Solfege ).
In . In
Meantone Temperament and
Equal Temperament these two intervals are approximated by the same interval.
The major second is considered one of the more
Dissonant intervals of the
Diatonic Scale .
