The sixth , also sixth (from Latin sextus : "the sixth") is an interval in music that spans six tones (five tones) of a diatonic , heptatonic scale (e.g. C → A ). In a narrower sense, the sixth also means the sixth degree of the respective scale.
The sixth interval can appear in four variants. Are common
- the major sixth (a) and
- the minor sixth (b),
- the excessive sixth (c) and
- the diminished sixth (d),
In the equal tuning , the sixth intervals are seven to ten semitone steps.
