Once you have finished getting started you could add a new project or learn about pygame by reading the docs. I don't agree that "FFT is just the name of a family of algorithms capable of calculating the Fourier Transform quickly." The FFT doesn't *calculate* a Fourier Transform, it *approximates* one. A Fourier Transform itself is just an algorithm and a Fast Fourier Transform is a different algorithm that produces approximately the same result.

Feb 10, 2016 · Nice post, John, and very clear. One minor point: in the Baroque period, pitches tended to be low, between A-392 and A-435, but Venetians and others tuned as high as A-465; A-415 is a modern standard for historically informed Baroque performances, but it has little justification — like much “historically informed” performance practice, in my opinion.
