:) What Is the First Musical Instrument Played Without Being Touched?

The answer is – theremin.  Invented by Russian Léon Theremin in 1919, it consists of two radio frequency oscillators and two metal loop antennas. The electric signals from the theremin are amplified and sent to a loudspeaker.


The theremin is widely associated with "alien" or surreal sounds, and has been used in films like Spellbound, The Lost Weekend, and The Day the Earth Stood Still, to name a few.


The following 2 minute recording from a radio interview by Robert Moog, describes how theremin works: http://www.theremin.info/download-file-37.html.
