1 Pitch Is Proximity The vertical antenna reads hand distance as frequency — the closer the hand, the higher the tone climbs.
2 Volume Without Contact The horizontal loop governs amplitude; pulling away from the field dampens the signal into silence.
3 A Voice Without a Body The theremin sings in continuous glissando, never resting on discrete notes — pure frequency in motion.
4 Wood Anchors the Signal The mahogany cabinet shields the oscillators from stray capacitance, grounding the ether in craft.
