Answer:
Well I don't know what the actual questions are, if there are any questions, but here is what I know.
Explanation:
1. Classical.
2. I can think of Johann Christoph Friedrich Bach, who was a harpsichordist, as well as a composer. He was known as "Bückeburg Bach", who was taught music from his father, and a distant cousin named Johann Elias Bach.
3. Number one instrument, I would say is the Violine (Violin in German.), considering the Violine was the most popular classical instrument used in any classical piece.
(I assume I can pick any classical, but, if not, I apologize.)
4. udwig van Beethoven – Symphony No. 5 In C Minor, Op. 67, "Fate": I. Allegro Con Brio was composed for none other than J. F. M. Lobkowitz
Andreas Razumovsky.
5. Beethoven premiered Symphony No. in C Minor at the Theater an der Wien, Vienna, composed from 1804, to 1808.
6. Beethoven wrote the Symphony over the space of some four years, beginning in the spring of 1804, during the most productive period of his career.
Hope this helped, mate.
