The instrument you do not touch.

Published 21 October 2026 · WHV · Public-source editorial note

The most surprising part of an Etherwave is the space it leaves empty. There are no strings to press or keys to mark out a scale. A player works around an upright pitch antenna and a loop-shaped volume antenna, making a musical gesture without touching the instrument’s playing surfaces.

Air becomes the playing surface

Moog’s support account explains the volume relationship particularly clearly. Moving a hand towards the loop quietens the sound, while moving away makes it louder. The movement supplies articulation as well as loudness. Producing a convincing musical phrase is therefore not the same thing as demonstrating that an electronic instrument can make an unusual noise.

The photographed example was assembled from a Moog Etherwave kit and recorded in 2005. Later Etherwave versions differ. Moog’s separate 2022 support material describes a pitch-control-voltage output, but that feature should not be transferred automatically to an earlier kit instrument. A familiar name does not make every generation interchangeable.

Learn the particular instrument

Listen to a skilled player, then try shaping a few quiet notes yourself. Notice how the lack of a fixed contact point changes the learning problem. When investigating an instrument, establish the exact version, power supply, working condition and available specialist help. The valuable thing may be the relationship you develop with it. An electronic object can invite a demanding bodily skill rather than removing the person from the process.

The photograph identifies a kit-built Etherwave in 2005, not the 2022 model, a newly available kit or a tested instrument. Later control-voltage features are not assumed on the pictured unit. WHV has not played or inspected it.
