mubone project page


The mubone is an experimental class of trombones that has embedded technologies such as an orientation sensor (like the one used in smartphones). Musical instruments with sensors are commonly referred to as augmented instruments. When programmed to audio or visual processing software, augmented instruments have the potential for extending the creative range of the instrumentalists in ways we believe may offer a lifetime of exploration. 

Travis West and I have been researching, developing, and creating with the mubone since 2018.


The sensor that has been a throughline in all prototypes is the orientation sensor. The device is semi-permanently attached to the tuning slide via a nut-and-bolt system and does not interfere with the playability of the host instrument (trombone). Orientation refers to an objects relative position, i.e. if it's upside-down, tilted left or right, pointing north or south.

orientation tracking
The sensor tracks the orientation of the trombone, now mubone, and the data can be used in a number of ways. The mubone and trombone has an inherent directionality; it is always pointing somewhere. The information about where the mubone is pointing (an x y vector) is one of many data streams we can use.

Once the data is calibrated, we can use the mubone and its orientation (or movements and gestures), to control software that can be custom programmed to receive control inputs e.g. Ableton, Max/MSP. For example, I can record and playback a sound in a specific location based on where I am pointing. 

artistic research

solo movement and sound performance
In Garcia, I am planting (playing) trombone sounds in pre-determined zones such as ground, horizon, sky. Each zone processes the recorded sound in different ways. The result is a mix of the acoustic and processed sound, which is further manipulated by the oriention of the mubone and my movements.

site-inspired improvisations
For the project Conversations with Space and Architecture, the environment becomes a source of inspiration both acoustically and visually. The frame of a building can be used as a graphic score for the mubone to trace, giving the impression that mubone slide is a big sound paintbrush.

movement and sound collaborations
The mubone opens the door for working across disciplines, most notably with movement and dance. The instrument extends the body and transforms movements and velocity into sonic gestures that are capable of being spatialized in surround sound. 

interdisciplinary performance art
One of the aims of the mubone is to provide a means for working in various modalities, or better yet, to be modality-agnositic. When taking an object-oriented approach to the instrument, the technology behind the mubone enables extramusical pathways towards other disciplines. 

large ensemble works
The mubone and the performance practice that we are developing for it will ideally be made available to all instrumentalists and performers. We have explored creating works for mixed (augmented and traditional) instrumentation and have ambitions to work with fully augmented ensembles.
