Microtub

Microtub is a trio of microtonal tubas formed in 2010 around the British, Berlin-based tuba player Robin Hayward, with the Norwegian tubist Martin Taxt. The group describes itself as the first ensemble of microtonal tubas. Since 2012 it has worked in just intonation, using the Hayward Tuning Vine (a visual map of the instrument's harmonic space) for its graphic scores. Hayward developed the first fully microtonal tuba with the German maker B&S.
