Major sixth Play ⓘ Pythagorean major sixth Play ⓘ, 3 Pythagorean perfect fifths on C. In music theory, a sixth is a musical interval encompassing six note letter names or staff positions (see Interval number for more details), and the major sixth is one of two commonly occurring sixths. It is qualified as major because
The size of an interval between two notes may be measured by the ratio of their frequencies.When a musical instrument is tuned using a just intonation tuning system, the size of the main intervals can be expressed by small-integer ratios, such as 1:1 (), 2:1 (), 5:3 (major sixth), 3:2 (perfect fifth), 4:3 (perfect fourth), 5:4 (major third), 6:5 (minor third).
The pattern of whole and half steps characteristic of a major scale. The intervals from the tonic (keynote) in an upward direction to the second, to the third, to the sixth, and to the seventh scale degrees of a major scale are called major. [1] A major scale is a diatonic scale. The sequence of intervals between the notes of a major scale is:
Scales in the Lydian mode are major scales with an augmented fourth. The Mixolydian mode corresponds to the major scale with a minor seventh. The Aeolian mode is identical to the natural minor scale. The Dorian mode corresponds to the natural minor scale with a major sixth. The Phrygian mode corresponds to the natural minor scale with a minor ...
The Aeolian mode is the sixth mode of the major scale, that is, it is formed by starting on the sixth degree of the major scale. For example, if the Aeolian mode is used in its all-white-note pitch based on A, this would be an A-minor triad, which would be the submediant in the relative major key of C major.

The limit refers to the highest prime number fraction included in the intervals of a scale. All the intervals of any 3 limit just intonation will be multiples of 3. So 6 / 5 is included in 5 limit, because it has 5 in the denominator. If a scale uses an interval of 21:20, it is a 7 limit just intonation, since 21 is a multiple of 7.
The harmonic major scale has its own set of modes, distinct from the harmonic minor, melodic minor, and major modes, depending on which note serves as the tonic.Below are the mode names, their degrees, and the following seventh chords that can be built using each modal tonic or degree of the parent mode as the root: a major seventh chord, a half-diminished seventh chord, a minor seventh chord ...
