Feedback Ocarina - a DIY entry level instrument for feedback musicianship

Krzysztof Cybulski

Proceedings of the International Conference on New Interfaces for Musical Expression

Abstract

Audio feedback in its pure form is notoriously difficult to control, yet at the same time it has a lot to offer as one of the simplest methods of creating sound in an expressive, tangible way. In an effort to provide a simple, easily replicable feedback instrument, I'm proposing the Feedback Ocarina - a simple device, combining a 3d-printed variable frequency Helmholtz resonator with an inexpensive microphone cartridge. By opening and closing finger holes, it's possible to control the feedback frequency, much like with a standard, acoustic ocarina.
