Thanks to Google, I discovered the href=”https://fr.wikipedia.org/wiki/Thérémine” Thérémémine an instrument to produce music in moving the hands near two antennas without touching the instrument. The artist virtuoso of this instrument was Clara Rockmore, a Russian artist born in 1911. The sound of this instrument is similar to that of the human voice that would filter between his lips. Listen to this interpretation of Summertime
and to finish with this instrument, the amazing Ave Maria, whose sound is a bit disappointing compared to the human voice
This instrument opened the voice of the so-called electronic music. In 1928 Maurice Martenot invented the ondes Martenot. In front of the keyboard, a wire connected to a metal loop in which the player slides his finger-lets make théréminesques glissandos while having visual control of notes played. On the left of the instrument, the expression key to handle the volume and the sound of the instrument.

There is the glass harmonica, invented by Benjamin Franklin in 1761. This instrument is based on the principle that sound more or less water is drawn from a glass filled by passing the finger over the edge.
Here is an overview of the instrument by Michel Deneuve, who defined it as a sensual instrument, because it is necessary to touch the glass rods to express the sound.
