electrophone

An electrophone is a musical instrument that produces sound by electrical means. This broad category encompasses a wide variety of instruments, from early electronic pioneers to modern synthesizers. The fundamental principle is the conversion of an electrical signal into audible sound, typically through loudspeakers.

Early electrophones, developed in the late 19th and early 20th centuries, included instruments like the Telharmonium, which generated sound by rotating dynamos. The Theremin, invented in 1920, is another notable example, played by controlling electromagnetic fields without physical contact. These instruments often produced unique timbres that were difficult to achieve with traditional acoustic instruments.

The development of vacuum tubes and later transistors revolutionized electronic music. Synthesizers, which emerged in the mid-20th century, allowed for unprecedented control over sound parameters such as pitch, timbre, and amplitude. Instruments like the Moog synthesizer became iconic, influencing countless genres of music.

Modern electrophones include digital synthesizers, samplers, workstations, and digital audio workstations (DAWs) which are software-based instruments. The accessibility and versatility of these instruments have made electronic music production a widespread practice. Electrophones continue to evolve, with ongoing advancements in digital signal processing and user interface design.
