Are parallel octaves allowed between outer voices?

Are parallel fifths allowed 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.

Why should you avoid parallel fifths?

Parallel octaves and fourths

Consecutive fifths are avoided in part because they cause a loss of individuality between parts. This lack of individuality is even more pronounced when parts move in parallel octaves or in unison. These are therefore also generally forbidden among independently moving parts.

Are consecutive octaves allowed?

This is allowed, because the parts don’t change notes. Consecutive octaves are just as bad as consecutive 5ths. Consecutive octaves can sneak in just about anywhere, so always be on the look out for them! Check for consecutive octaves between all six voice pairings, as above.

Can you double the leading tone?

Never double the leading tone, so don’t double the root if the root is the leading tone. Don’t double the third, except if the chord is diminished, in which case it’s good to double the third.
