Question

Why might it be confusing to compare the stylistic periods in art with similarly named periods in music?

Answer 1

Because art and music are influenced by different things, and the times in which each period happened could be at completely different times throughout the years. Both change styles during different times in history. To accurately depict the similarities between the two you would most likely have to compare them by times in history (the 60,'s, 70's, 80's etc.) instead of stylistic periods.

Answer 2

Because they evolve at different rates even though they are both art forms. They had different influences the time period wont effect it.
