Experience the Canto in Krystal Tuning
Sandra & Jeroen van Veen playing the Canto Ostinato ('76) by Simeon ten Holt (1923 - 2012) on two Erard grand pianos in the new Krystal tuning, divided over 196 keys.
One piano is tuned in A-432Hz, the other in A-434,92Hz, together creating a yin/yang of 'krystal sounds'. Experiments to integrate both on one piano have also been made. Just to confirm, this is not equal temperament, our current musical tuning.
Try around 32min30sec or around 36min20sec and hear the ringing sounds. For more information, enter the introduction page.
