Why a passing siren drops in pitch.

Read the scoreApple Music

The equation

f′ = f · c / (c − v)

Every lead note is one passing car. The faster the car, the bigger the fall, so the melody is really a sequence of speeds.

What was composed

Hook rhythm, the order of speeds, chords, tempo and drums.
