Parallel motion between two voices occurs when both voices move in the same direction by the same melodic interval. Only the generic size of the [[melodic interval]] matters, not the specific quality. In **Example 1** below, both voices move upward by seconds. The upper voice moves by minor second from B to C while the lower voice moves by major second from G to A. Because parallel motion preserves the generic size of the starting and ending harmonic intervals, we would say of **Example 1** that the voices are “moving in parallel thirds.” **Example 1.** Parallel motion. ![[example parallel motion.png]] ![[example parallel motion.mp3]]
