Cool (Gwen Stefani song) [SEP] Composition
"Cool" is a mid-tempo love song featuring a synth-pop and new wave production. The song is composed in D major. It is written in common time, it moves at a moderate tempo of 112 beats per minute, and it has a vocal range from the low note of F♯ to the high note of C♯. The song is written in the common verse-chorus form, featuring five instruments: bass guitar, drums, guitar, keyboards and synthesizer. "Cool" opens with all five instruments, and as Stefani begins singing, the synthesizer is lowered, and the hard-hitting drum beat steadily increases in volume. She performs her highest pitch (C♯) during the chorus, after which she sings in a softer, almost "sotto voce", and her lowest pitch (E) at the beginning of the verses.
