1. I would say Fallingwater (initials, FLW, his name) would be the most famous
2. Haven't seen your tutorial, but as an architecture student I would say it's about nature, materiality and inside/outside
Answer:
This first movement of Vivaldi's Spring concerto from The Four Seasons is an excellent example of RITORNELLO form that features an instrumental refrain with contrasting solo EPISODES. The solo instrument is a VIOLIN, and it represents various images from a SONNET about spring. The work is an example of program music because of this literary link.
Explanation:
Antonio Vivaldi was an Italian composer and violinist. He is considered the pioneer of the Baroque music. The Four Seasons is perhaps one of his most famous pieces. Written between 1716-1717, it wasn't published until 1725. The Four Seasons (Spring, Summer, Autumn, and Winter) all are individual pieces, each divided into three parts.
