Wibrafon

Wibrafon is an experimental musical instrument described in contemporary music literature as a hybrid of percussion and electronic synthesis. It typically consists of a set of tuned metal bars arranged in a keyboard-like frame, which can be struck with mallets to produce acoustic pitches. In many proposals, the bars are augmented with passive or active pickups, allowing the performer to blend the resonant bar tones with digitally generated timbres or processed sounds.

Designs vary widely. Some wibrafons use a conventional vibraphone-style chassis with motor-driven dampers and resonators, while others dispense with resonators entirely and rely on built-in synthesis. Electronics may include MIDI or USB interfaces, programmable voices, effects, and envelope controls. The instrument can be played acoustically, electronically, or in hybrid modes where bar strikes trigger samples or synthesis through external sound systems.

Technique and repertoire: Played with standard vibraphone or mallet techniques, while performers may manipulate aftertouch, velocity-sensing, or bar damping to shape sound. Because of its hybrid nature, the instrument is used mainly in experimental ensembles, electroacoustic works, and some film or multimedia scores. It is often discussed as a concept illustrating possibilities for integrating tactile percussion with digital sound design.

Status and sources: The term wibrafon appears in a number of niche sources and DIY projects; there is no single standard design or widespread adoption. As such, the instrument is best described as an evolving concept in the field of electronic percussion and extended instrumental techniques.
