Many contemporary performers and composers seek new sounds through extension of traditional instrument techniques. For the trumpet one such extended technique is valve rotation, the rotation of a trumpet piston valve within its casing to effect the timbral complexity of airstream effects. Intrigued by the possibilities, I have embarked on an exploration of trumpet valve rotation, a path which has become significant to my creative practice. When searching for resources to inform my exploration it was evident that there is limited: documentation referring to trumpet valve rotation; investigation into the application of trumpet valve rotation in improvisation and composition; and methods for the effective communication (both aural and written) of the technique. Through the creation of two original works for solo trumpet and the development of both a static and animated notation this practice-based research aims to address these gaps in the academic literature. In addition detailed description of the physical parameters, sonic characteristics and best practice when using trumpet valve rotation are included. The included creative works are: iMprov #13 (2017) — solo trumpet improvisation, and Minutiae (2017) – for solo piston valve trumpet.
