I swear to god Im going to lose my mind no one agrees on octave numbering and I get more and more confused with each google search is middle c different from c4? Who knows
there is no universal agreement on octave numbering, but there is universal agreement on 'middle C'. middle C is the one that's approximately 262hz. for octave numbering, a lot of people say that's C4, but then i think Yamaha calls it C3, and then some sources call it C0. that's why i don't use those. but 'middle C' is solid
