Final answer:
In music, when a melody moves from one tone to a non-adjacent tone, it moves by 'disjunct motion'. Disjunct motion involves intervals larger than a major second, unlike conjunct motion which is stepwise.
Step-by-step explanation:
When a melody moves from one tone to a tone that is NOT adjacent, it is said to move by disjunct motion. Disjunct motion, also known as skipping or leaping, occurs in a melody when the interval between one note and the next is larger than a major second. In contrast, conjunct motion refers to stepwise movement in a melody, where each note moves to the next adjacent note in scale. Harmonic motion refers to the progression of chords, and parallel motion occurs when two or more lines of music move in the same direction and maintain the same interval between them throughout.
