An artist places a notebook and pen in the gallery of his latest exhibition and ask viewers to leave comments about his work. he is trying to hwlp audience members become what type of observers?

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.
