Why was "C MAJOR" chosen to be the scale with no sharps or flats?

Answer 1

Well, I don't think it was chosen. Look at a piano keybord and notice that from C to D is a whole tone. From D to E, a whole tone. From E to F, a half-tone. From F to G, a whole tone. From G to A, a whole tone. A to B, a whole tone. Finally, from B to C, a half-tone. That will bring us back to "doe."

Now all this was accomplished without touching any black keys, consequently, there are no flats or sharps. I don't know the reason why, it's just how the piano evolved over the years. Hope this helps you.

Answer 2

b/c the person who decided didnt know their alphabet!
