According to https://pages.mtu.edu/~suits/notefreqs.html, with A4 at 440 Hz, aS and b should be at 466 Hz and 494 Hz respectively. Besides that, I ran the code on my Arduino and I liked it very much!

Here's improved timing, typing and 2 notes frequencies that @GeoVa19 mentioned earlier, refactored a bit and added some comments
