What Beethoven wrote for the Yaybaharmain
This gorgeous instrument was invented by Görkem Şen of Istanbul.
It works like this: The vibrations from the strings are transmitted via the coiled springs to the frame drums. These vibrations are turned into sound by the membranes which echo back and forth on the coiled springs.
At around 4:40, Mr Sen plays a theme from Beethoven’s Ninth. Enjoy.
