Answer 1

Well, if you listen to the "four seasons" from Vivaldi, you'll hear the most dominant instrument is indeed, the Violin.
Which is completely intuitive given the composition of the orchestra it was notated for, for further details, check out my tutorial on bowed strings and their function in the orchestra:

We can categorize Vivaldis "four seasons" as a violin concerto and orchestra because of the instrument being heavily implemented and having most of the solo sections.
