The musical interval of a major second —
also called a whole-tone — is the relationship between the first note (the root or tonic) and the second
note in a major scale (and also a minor scale). It is the inversion of the
minor seventh. It is abbreviated as M2.
It can be produced by starting on a high note and playing the second below or by starting on a low note and playing the second
above.
A major second in just intonation corresponds to a pitch ratio of
9:8 or 1:1.125 while in an equal tempered tuning, a major second is
equal to two semitones, a whole-tone, a ratio of 1:22/12 (approximately
1.122), or 200 cents, 3.910 cents smaller.
The major second is considered the most dissonant interval besides the
minor second and major
seventh.
