Explanation:

ur awsome

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.  

i think it's about 10 mins.

actually i think that's wrong, but i don't know how to delete this.

but who knows it might be right.
