Microtonal Projects (Stephen Altoft, trumpet and flugel horn; Donald Bousted, electronics) present works by Stephen Altoft and Donald Bousted for 19-div trumpet and microtonal flugelhorn (48-div, just intonation) with electronics.

This is the first performance of Stephen’s microtonal flugelhorn, which arose out of a talk Stephen gave as part of EUROMicroFest 2017. This year Stephen has been working with Siegmar Fischer of Musik Gillhaus on the conversion: the quarter-tone valve and the 1/19-div valve (both with in-built slides) are exchangeable. As with the microtonal trumpet conversion kits, the 19-div set-up requires exchanging slides and also employs ‘remember rings’ to hold slides at the required lengths.
