I can't remember if I might have posted this here before, but I don't think I have.
This is a BBC TV movie, and at the same time, it's a performance of Beethoven's 3rd symphony. It's a regular movie with characters, plot, dialog, costumes, cinematography; and the orchestra are among the characters as well.
It's a real orchestra playing period correct instruments; and it's a portrayal of the original orchestra's sight reading the 3rd symphony for the first time, among other plot elements; a private premier of the piece for one of Beethoven's benefactors. It's based on the actual event, including the "mistake" by the horn player.
The piece itself was revolutionary for its time, as is shown in the comments of the listeners and orchestra members.
In my view, the movie enhances one's appreciation for the piece. And it's a wonderful performance of a great piece of music.
