Hello guys I'm a little confused on the meaning of parallel motion.

For example if I have these notes.

G > A > B
C > D > E

Is this considered parallel motion in fifths because the interval relationship between them are all perfect fifths?

Or...

G > D > A
C > G > D

Is this considered parallel motion in fifths because the distance between each note during the chord changes are perfect fifths?

Both of those would be parallel motion. Parallel motion is when two notes move by the same interval. When the two notes are a fifth apart and they both move by the same interval, you get parallel fifths.



It doesn't matter what interval the notes move by as long as it's the same.

I see thanks for clearing that up for me.

Another question.

Is parallel motion diatonic to the scale?

For example if there is parallel motion in thirds does that include both the minor thirds and the major thirds in the scale?

If there was parallel motion in fifths does that include the diminished fifth that occurs on the 7th degree of the scale?

Well, technically, parallels are specific, so there is a difference between parallel minor 3rds and parallel major 3rds.

In practicality, however, when someone says "parallel 3rds/6ths" they're talking about both major and minor and when they say "parallel fifths/octaves" they're talking about perfect intervals.
