Unaccented Passing Notes

Complexity : 3/10 (simple)

A passing note is termed 'unaccented' when it is on a weaker beat or part of beat than the note that precedes it.
- Two passing notes may be used simultaneously in different parts, provided they move in parallel 3rds or 6ths. (called unessential 3rd or 6th). The movement MUST be parallel. Unessential 3rds or 6ths must NOT be quit in contrary motion.
- Two parts may take the same passing note simultaneously in contrary motion, at least an octave apart.
- Passing note and harmony note should be struck together only if the form a concord (3rd, 5th or 6th).
- Avoid passing notes that produce a minor 9th above the 3rd or 7th of the scale.
- Introducing passing notes increases the danger of introducing incorrect harmonic progressions (consecutive 5ths or 8s, exposed 8s etc). Parts that are incorrect without passing notes are incorrect with them. In addition, passing notes may also produce consecutive 5ths or 8s which also must be avoided.
- Never have more than 2 passing notes simultaneously. It creates congestion.
