Write the name of the key under the key signature. You should use each of the following keys once and only once. Cross them off as you use them. Can someone help plsss

this is you second time asking this question

Explanation:

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.
