Rules of harmony Flashcards
Rule 1:
No consecutive 5ths in the same pair of voices. 5th have very strong stability and resistance to forward motion, and are the only interval that can define a triadic root.
Rule 2:
No consecutive octaves. When there are octaves in the same two parts one after the other, we call them “consecutive octaves”.
Rule 3:
No hidden consecutives. Hidden consecutives happen when:
- The bass and soprano parts form a perfect 5th or octave AND
- The 5th/8ve is approached by similar motion AND
- The soprano part is approached by a leap (not by step).
In all voices, leaps of which intervals are not allowed?
7th, aug. 2nds, and aug. 4ths
leading notes in dominant chords always resolve to what note?
tonic
Always choose what kind of interval if it’s available?
semitone step
For vocal melody writing, avoid leaps greater than:
a perfect 5th
For vocal melody writing, the best intervals to use are:
2nds and 3rds
For vocal melody writing, what can easily become boring?
repeated notes
What notes can you double in chords?
- Root position – 1 or 5

Watch out for: - diminished chords (ii° and vii°) – ONLY double the third
- chord VI in minor keys CAN double the third
Vb – CAN’T double the third

octave
Men’s church range
