Graphical sound is an early electroacoustic technique and aesthetic in which audio is generated from drawings, stencils, or photographed shapes placed on optical film soundtracks. Instead of recording a vibrating source with a microphone, composers directly designed waveforms and spectra, then scanned them with optical readers to produce sound.
Emerging in the Soviet Union and Germany, practitioners treated sound as visible geometry: curves set the waveform, patterns set the spectrum, and motion through time created phrasing and rhythm. The result ranges from pure tones and microtonal glissandi to dense, noise-like texturesâpredating and foreshadowing later tape, electronic, and spectral practices.
Graphical sound arose from film laboratories and avant-garde studios investigating optical sound-on-film. In the USSR, Arseny Avraamov pioneered "ornament sound" by hand-drawing periodic shapes on film to directly synthesize tones. Evgeny Sholpoâs Variophone system (Leningrad) used rotating discs with printed waveforms to build polyphony photographically. Nikolai Voinov and Boris Yankovsky developed "paper sound" workflows, cutting and photographing patterns to craft timbres and sequences.
In Germany, Rudolph Pfenningerâs "TĂśnende Handschrift" and Oskar Fischingerâs drawn-sound experiments showed that graphic ornament could become audible when printed into the optical soundtrack area. These experiments established a composerâs control over timbre, pitch, and envelope without microphones or traditional instruments.
The aesthetic and technique spread through animation and film studios. Norman McLaren at the National Film Board explored hand-drawn soundtrack strips for synchronized audiovisual works. In the UK, Daphne Oram later advanced drawn control with her Oramics systemâpainting control curves on film to shape sound parameters.
In the Soviet lineage, Yevgeny Murzinâs ANS synthesizer (1958) translated images on a glass score into sound via bands of light and photoresistorsâan iconic continuation of the graphical-synthesis idea.
Graphical sound anticipated many core ideas of electroacoustic music: timbre-as-structure, microtonality, direct spectral design, and imageâsound translation. Its methods influenced tape music, musique concrète, electroacoustic composition, sound art, and later spectral and glitch aesthetics. Modern software (e.g., spectrogram painting and image-to-sound tools) revives the approach, enabling contemporary composers to "draw" sound with high resolution while preserving the movementâs timbre-first philosophy.
Think of sound as an image. You design the waveform or spectrum directly, then translate it into audio by scanning it across time. This prioritizes timbre, microtonality, and continuous gesture over traditional harmony and meter.
