IF you think about it, a music sheet is just a graph of Fourier transform. It shows at any points of time, what frequency is present (the pitch of note), and for how long (duration of note),

it is no such thing. nobody maps overtones on sheet, durations are toast, you need to macroexpand all flat/sharps, volume is passed by vibe-words, it has 500+ of historical compost and so on. sheet music to fft is like wine tasting to a healthy meal
