LESSON 2 · The Science of Sound & Song

Crafting Memorable Melodies

Songwriters follow patterns that make melodies stick. Stepwise motion — moving to neighboring notes — creates smooth, singable lines, while leaps to distant notes add drama. The best melodies balance both.

Consider "Somewhere Over the Rainbow." It opens with a dramatic octave leap upward, then steps back down gently — that single leap captures the whole song's yearning. "Mary Had a Little Lamb," by contrast, is almost all stepwise motion: simple, predictable, perfect for children.

Melodic contour — the shape of a melody drawn as a line — matters more than the exact notes. People recognize melodies by their contour even when transposed to a different key.
