Description
This is ONE function: a sum of 150 sine waves. At every moment it plays the nearest note, and out comes Happy Birthday.
y(t) = sum over k = 1..150 of a_k cos(2Ï€kt/25) + b_k sin(2Ï€kt/25)
The coefficients a_k and b_k are the Fourier series of the melody, computed exactly.
Melody: "Happy Birthday" (public domain, from "Good Morning to All", 1893). All sound synthesized from math functions.
