Which characteristic of sacred music changed most significantly between 1100 and 1500? a. pitch b. texture c. language d. tempo

Hey!  The correct answer to your question is:

B. texture.

Good luck.

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.
