e-Trombone is a novel electronic instrument built with PVC pipes, custom sensors and Moog Werkstatt analog synthesizer, allowing players to create brass-like sounds through different blowing techniques. The instrument is played like a conventional trombone, and the addition of electronic circuits powered by Moog Werkstatt and Teensy (an Arduino-compatible development board) allow for sounds that would be impossible with a traditional trombone.

This project won first place of Gerogia Tech’s (GT) annual Moog Hackathon, a 48-hour invention marathon to build electronic instruments at GT School of Music. As part of the prize, we were accepted as finalist of GT’s prestigious Guthman Musical Instrument Competition, an event dedicated to identifying the newest and greatest ideas in music, with 10 invited inventors from around the world sharing their creations and ideas about the future of music. We paired up with Atlanta-based musician Samuel Cape and he made a beautiful performance using our e-Trombone. Check out the video below!

Creators of e-Trombone, besides me, are Ruhan Yang from University of Colorado Boulder and Xiangyi Li from Georgia Tech. Ruhan is a designer and an engineer working on designing educational toys and tools. Xiangyi is a tech lover who specializes in programming and app design. The collaborative efforts in the aspects of design, engineering and music made this project happen.

Ruhan Yang and teammates win first place at Georgia Tech's Moog Hackathon

The Guthman New Musical Instrument Competition

  • Showcase on Moog Hackathon at Invention Studio of Georgia Tech

  • An overview of electronic circuits that support wind sensors and slide sensors. Special thanks to Pengyu Gu, a graduate student in Electrical and Computer Engineering, who helped a lot in the circuit design and soldering.

  • During the 2020 Guthman Competition, each finalist was paired with a skilled musician from the Atlanta area. We were glad to have musician Samuel Cape at the stage of Ferst Center for the Arts of Georgia Tech to make the debut of e-Trombone.

  • With Sam's Moog Mother 32 synthesizer and many other modules in his collection of Eurorack, the expressive power of e-Trombone was further expanded to its full limits.
