10min. Gallery Talk "Theremin"

[10min Gallery Talk] 9/7 (Wed), 9/9 (Fri)：Theremin
L. Theremin, who is French Russian, invented this instrument.
The distance between the antenna on the instrument and the player's hand creates a frequency beat above the instrument.
Then, the frequency beat is amplified from the speaker and becomes sound.
Therefore, a player plays the instrument without touching the instrument.
