The tip of the endpin, 11 inches from the cello body that is suspended in the air, is almost sympathetically vibrating with a C (66 Hz) tone from a pizzicato.
Behind the cello, a metronome beats a 200 tempo (3.3 times/sec).
Thanks to the technology of the Sony Cyber-Shot RX100M4. 32 times slower, 960 fps.
32倍スローモーションで見たエンドピンの先端の振動です。C音(66Hz)のピチカート。
振動が伝わっているのがわかります。
