Answer:
a. Terraced dynamics
Explanation:
Terraced dynamics, a unique characteristic of Baroque music, has to do with a quick alteration in tempo or volume that does not involves a progressive crescendos and decrescendos. The harpsichord, the basic keyboard tool of the era, could majorly perform forte (loud) or piano (soft) only, and couldn't perform crescendo or decrescendo in between, and thus results in a quick shift in dynamics. It is a specific character of music that represents it's success.
In some cases, they were highlighted in the score, but a large sort of area, it was agreed upon mostly by the performers or were directed by conventions which was fully expressed to all musicians.
I don’t know sorry. You can maybe search it up on google
Art is considered many things...… from music to paintings. This is what everyone knows art as. But really art is what you end up with when your struck with an amazing idea or you see things from a different perspective and notice that it makes something else. The reason why the question "what is art" cannot be answered is because we don't really know what art is ourselves, our definition of art expands everyday when something new is noticed. I'm only in high school so maybe my answer is stupid and doesn't really help..... or maybe it will help. But seeing that no one else has answered your question, I thought I'd give my opinion. Hope this helps a little :)
