Where can I find good music from silent films?

Answer 1

Carl Davis has composed several modern scores for silent classics, as well as the score for the entire tv series Hollywood, which was about the silent era. You might check out his name at Amazon; organist Gaylord Carter also did several terrific scoring jobs; you could also check the Amazon listings for specific films for information on scoring.
I can't tell from your question whether you're looking for specific kinds of music, or from particular films, or just generic "silent movie" music.
Most of the original music for silent films was provided by in-theater pianists or organists, who, unless a specific score was provided by the movie studio to accompany the film, improvised a score as they watched the film unreel, using themes from pop classical pieces, old and familiar songs, current ballads, anything that came to mind that the audience would relate to the action on the screen.
The score for "Moulin Rouge!" did this in reverse, using modern songs and music to create the ambience of 1900 Paris!
When it comes down to it, you can use pretty much anything you want as a silent film score.
