CLEAN : Sound no barrier for worlds fastest pianist

The video discusses the natural speed limit for pianists, likening it to the maximum speed of an airplane propeller. It explains that while achieving speeds of 19.5 notes per second is possible, it surpasses the ear's ability to discern individual notes and requires significant physical energy. The natural speed for pianists is between 13 and 14 notes per second, which is necessary to achieve the true power of the piano, akin to breaking the sound barrier.
