European classical music:
currents, genres, styles

Classical music is grouped into layers: medieval, renaissance, baroque, classical and romantic. You can find the list of composers.
The composers are placed in significant places: where they came from or where they worked. The interaction with the touch screen or the mouse on the marks reveals a composer, a short description and one of their significant piece, which can be played through the built-in audio player.
