„A great piece of music is beautiful regardless of how it is performed. Any prelude or fugue of Bach can be played at any tempo, with or without rhythmic nuances, and it will still be great music. That's how music should be written, so that no-one, no matter how philistine, can ruin it.“
— Dmitri Shostakovich Russian composer and pianist 1906 - 1975
