...since long time ago. The emperor of the western music dies away slowly but surely. The last important piano work - Ligeti's Piano Etudes - most of them have been written more than 20 years ago with a strong focus on rhythm - the piano has become a percussion instrument. Again the lack of the harmony system in contemporary music took away the most important task of the piano: playing harmonies.
The piano can play almost everything fast and perfectly but the tone itself is rigid and cannot be changed after sounding - that's the weakest part of the piano and it will lead the piano to meaninglessness.
