parallel chords

A sequence of chords consisting of intervals that do not change as the chord moves. For example, a major chord of C, E, and G (with the intervals of a major third between the C and E and a minor third between the E and G) would be parallel to a following chord of {% f, A, and C (again a major chord with the intervals of a major third between the F and A and a minor third between the A and C), which, in turn, would be parallel to another major chord consisting of G, B, D, etc. This is also referred to as parallel motion.
