Please compare and contrast the two works above painted by Pablo Picasso. Be sure to address the following items: 1. Style/art period
2. Color
3. Elements of art such as line, pattern, space, and form
4. Talk about the subject matter. How is the subject interacting with the viewer?

the answer is b. i'm positive it's that answer.

a chromatic scale uses the twelve tones of the octave, while a regular scale only uses eight, or seven different notes (as the first note is played twice)

i believe their role is to instruct certain sections on when they are to join and when they are to stop
