Anyone listen to Fall out Boy

No

Explanation:

I prefer christain Rap and most relaxing sounds that i hear on my camping trips im a wildlife type person. But im sure i'll check that song out  

all options are correct a) b) c) and d)

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.
