List of fifth intervals
In the theory and practice of music, a fifth interval is an ordered pair of notes that are separated by an interval of 6–8 semitones.
There are three types of fifth intervals, namely
After the unison and octave intervals, the perfect fifth is the most important interval in tonal harmony. It is highly consonant. Its implementation in equal temperament tuning is highly accurate, unlike the major third interval, for example. As explained below, it is used to generate the chromatic circle and the cycle of fifths, and it is used for tuning string-instruments. It is a constituent interval for the fundamental chords of tonal harmony.Tonal harmony
The fundamental chords of tonal music—major and minor triads and also seventh chords—all contain fifth intervals.
Fifths are stacked to form chords in quintal harmony.Cycle of fifths
Concatenating the perfect fifths ,,,,, generates the sequence of fifths ; this sequence of fifths displays all twelve notes of the chromatic circle.Harmonization of scales in fifths
All but one of the intervals are perfect fifths. The interval is a diminished fifth.
Tuning of instruments
All-fifths tuning refers to the set of tunings for string instruments in which each interval between consecutive open strings is a perfect fifth. All-fifths tuning is the standard tuning for mandolin and violin and it is an alternative tuning for guitars. All-fifths tuning is also called fifths, perfect fifths, or mandoguitar tuning.
