I am looking for a database with classical music (approximately from the period of 1500-1900). What I need is just music (notes, names of composers/compositions, type of musical instruments the composition was designed for are nice to have but not important).
Ideally it would be a lot of compositions of Vivaldi, Beethoven, Wagner, Chopin, Mozart, Rachmaninoff and many many more whom I do not know. The quality does not really matter (as long as it is not distorted really much).
One option is to search for the names of composers and download their compositions, but this does not look appealing to me, mostly because of my lack of knowledge of the composers and even with googling I will not be able to find a lot of not well-known (for the amateur) composers.
Does anyone know where to get such a database?
