In music, consecutive fifths, or parallel fifths, are progressions in which the interval of a perfect fifth is followed by a different perfect fifth between the same two musical parts (or voices): for example, from C to D in one part along with G to A in a higher part.
Do parallel fifths sound bad?
Why are Parallel Fifths Bad? The intervals of the perfect fifth and the perfect octave produce what's known as open consonances (or perfect consonances). This means that these notes go so well together they almost melt into one sound.
Do parallel fifths matter in jazz?
Short answer: no, no effort at all. Avoiding these are rules of classical music and counterpoint, and they do not apply in Jazz.
Did Bach ever use parallel fifths?
Bach does not write stepwise chordal parallels. There simply are none. All stepwise parallels involve NCTs rather than being chordal consecutives. All chordal parallels (there are only 2, and both are fifths) involve leaps.
