Augmented Musical Instrument
An augmented musical instrument is a musical instrument extended with sensors, computation, or actuators that modify or enhance its expressive capabilities.
These systems expand traditional instrumental interaction by introducing computational mediation between gesture and sound production.
Scope
This category includes instruments that maintain a physical acoustic or electroacoustic core, while incorporating additional technological layers that alter their behavior.
The focus is on the transformation of instrumental expressivity through embedded or external systems, not on purely digital synthesis instruments.
The concept applies broadly across experimental luthiery, human–computer interaction research, and electroacoustic performance practice.
Key Properties
- Physical sound-producing structure (string, membrane, air, etc.)
- Sensor-based interaction (touch, motion, pressure, etc.)
- Computational augmentation of sound generation or transformation
- Real-time or near-real-time response to performer input
- Extension of traditional instrumental expressivity
Examples
The following system was designed and developed by Luciano Ciamarone:
- Feed Guitar - an electroacoustic guitar system with feedback-based actuation and embedded processing.

These examples represent broader research directions in augmented instrument design, not all of which are authored by the same individual.
