f(t)33 / 35Rage trap
sin(2pi f t)
The purest tone there is: a single frequency and nothing else.
The equation
y = sin(2πft)
What the equation decides
The lead's timbre. The pure sine of the verse is pushed harder until it flattens into a screaming near-square in the drops, then falls back to pure at the end.
What was composed
Hook, counter melody, chords and drums.
