Minor sixth Play ⓘ Pythagorean minor sixth on C Play ⓘ, four Pythagorean perfect fifths.. In music theory, a minor sixth is a musical interval encompassing six staff positions (see Interval number for more details), and is one of two commonly occurring sixths (the other one being the major sixth).
Interval recognition, the ability to name and reproduce musical intervals, is an important part of ear training, music transcription, musical intonation and sight-reading. Reference songs [ edit ]
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).
Comparison between tunings: Pythagorean, equal-tempered, quarter-comma meantone, and others.For each, the common origin is arbitrarily chosen as C. The degrees are arranged in the order or the cycle of fifths; as in each of these tunings except just intonation all fifths are of the same size, the tunings appear as straight lines, the slope indicating the relative tempering with respect to ...
In classical music from Western culture, a diminished sixth (Play ⓘ) is an interval produced by narrowing a minor sixth by a chromatic semitone. [ 1 ] [ 3 ] For example, the interval from A to F is a minor sixth, eight semitones wide, and both the intervals from A ♯ to F, and from A to F ♭ are diminished sixths, spanning seven semitones.
It is called a "sixth" because the interval between the bass note and the root of the chord is a minor sixth. For example, in the key of C major or C minor the chord consists of D ♭ (the root note), F (the third of the triad), and A ♭ (the fifth of the triad) – with the F in the bass, to make it a ♭ II 6 rather than a root-position ♭ II.
Unlike the major sixth chord which is often substituted for a major triad, the minor sixth is more versatile and plays a number of different harmonic roles due to its identity as an inversion of the half-diminished seventh chord. The presence of the perfect fifth interval over the root also means that this voicing is more stable than the half ...
The augmented sixth interval is typically between the sixth degree of the minor scale, ♭, and the raised fourth degree, ♯.With standard voice leading, the chord is followed directly or indirectly by some form of the dominant chord, in which both ♭ and ♯ have resolved to the fifth scale degree, .
