The theremin's sound is produced by the electronic principle of 'heterodyning' - when the frequency of the 'pitch' oscillator is subtracted from the frequency of a fixed oscillator, the resultant frequency produced falls within the range of human hearing, and this is what we hear through a speaker as sound.

29 Δεκ 2004 · The theremin is played by carefully moving your hands near 2 antennas, one for volume and one for pitch. But how does it work? If you mix the signals of 2 rf oscillators, you will get many output signals. The most important signals are the sum and difference of both frequencies.
The Theremin has two very high frequency oscillators (around 350 kHz). One of them is fixed, and the other is varied by the capacitance of your hand: it's the difference between the two frequencies which decides the pitch.
The mixer produces the audio-range difference between the frequencies of the two oscillators at each moment, which is the tone that is then wave shaped and amplified and sent to a loudspeaker. To control volume, the performer's other hand acts as the grounded plate of another variable capacitor.
8 Ιαν 2024 · Knowing the ranges that instruments and voices occupy in the frequency spectrum is essential for any mixing engineer. Sweetwater has put together a Music Instrument Frequency Cheatsheet, listing common sources and their “magic frequencies” — boost/cut points that will produce pleasing results.
14 Δεκ 2018 · The theremin has a playable range of approximately five octaves, from C2 to C7. The most comfortable playing tessitura overlaps with the human voice and the common stringed instruments. With some adjustments, the overall range of the instrument can be extended to cover eight octaves, from A0 to A7.
