English
Noun
cycle of fifths (also circle of fifths)
- (music theory) A sequence of bass notes at intervals of a perfect fifth lower than the previous note. In equal temperment the sequence repeats every twelve tones, forming a cycle.
#: The composition modulates upwards through the cycle of fifths, eventually returning to the original key.
To keep the music in range it is very common to have the bass notes go gown a fifth, then up a fourth, and so on. This pattern still produces the same series of notes, e.g E-A-D-G-C-F-Bb
