Who are thes 2 characters??

I frogot but haikyu something like that theres a lot of r34 of them

the one with orange hair is Hinata and the other one is Kageyama

Explanation:

They're both from Haikyuu!! which Is an anime you can find on Netflix ;)

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.
