Which part of a classical program gives background information on the musicians?

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.  

the answer is letter b. false. fugue is a complex musical composition that does not occur or come together at the same time. in fact, it is composed of a number of voices or parts where the theme is introduced in one part and successively imitated in other parts.
