Classical violin. Getting a good sound. Finger dexterity. Pitch discrimination.
Unnatural holding position. Bowing technique. Neck problems. Chin sores.
How does Itzak do it?

Solo classical piano. Reams of music paper in your fingers. Memory taxing.
Nerves, nerves, nerves.

Operatic voice.   Fast burnout. (Like a sports figure).   Sing over an orchestra?
Gotta' act, too. And gain weight.

The theremin (/ˈθɛrəmɪn/[1]), originally known as the aetherphone / etherophone or termenvox / thereminvox is an early electronic musical instrument controlled without contact from the player. It is named after its Russian inventor, Professor Léon Theremin, who patented the device in 1928. The controlling section usually consists of two metal antennas which sense the position of the player's hands and control oscillators for frequency with one hand, and amplitude (volume) with the other. The electric signals from the theremin are amplified and sent to a loudspeaker.

Duet with musical saw and kazoo playing the 1812 Overture by Tchaikovsky. Hardest two instruments.


In reality, any instrument played well is hardest.
