I am writing a chorale in C flat major and I currently have a 3 chord going to a I6 chord. Stacked, the chords are EGEB to EGEC. Is this considered parallel octaves? HELP.
Just to add to Patrx2 answer there are a total of four types of motion in counterpoint. They are:
- oblique - one note moves while the other doesn't
- contrary - the notes move in the opposite direction
- similar - the notes move in the same direction, but different intervals (i.e. one moves a 2nd and the other moves a 3rd)
- parallel - the notes move in the same direction by the same interval
In your example the two notes in question don't move so there is no motion so nothing above applies. It may seem like a lot, but you can ask yourself a few questions to figure out what motion is being used between any two notes.
Does only one note move?
- If yes then the motion is oblique.
- If no then continue to next question.
Do they both move the same direction?
- If no then the motion is contrary.
- If yes then continue to next question.
Do they both move the same interval?
- If no then the motion is similar.
- If yes then the motion is parallel.
No. If the notes don't move, they aren't parallel octaves. Repeated notes act very much like tied notes. If you had moved both Es down to their respective neighbouring Ds, leaving the tenor and soprano static, that would be an example of parallel octaves.
