Nice. A couple of quick thoughts:

- It might be educational to show the sum of sine waves in addition to the components.

- 55 Hz is really low as the base frequency. I think going up a tiny bit would make it easier to hear the base frequency as you add overtones.

- I think the counting you use might be nonstandard: what’s called the “1st harmonic” should actually be the second harmonic, twice the fundamental frequency. But please double check me there.
