Studie fur 19ton Trompete

I drafted this "STUDY" for Steve Altoft using the "hybrid" possibilities on the 19tone trumpet between the 19-division scale and just intonation. So in addition to the 19tone scale I make use of the natural harmonics on he trumpet, especially the 5th partial.
The basical melodic line uses simple spectra and transitions to distorted spectra. It is later multiplied by a computer working in real-time, which means in this case time-shifting as well as octave-transposing (for the 4th lower line).
