Radix
(lat. ‘root’, the number of unique digits in a positional numeral system, ie. ‘base’)
Quite early in the composition process of my brass quintet Radix (2013), it became clear that the brass instruments have a lot of material potential. Compared to string and woodwind instruments, the properties in brass seemed to be somewhat understudied. With the help of several broad-minded brass players in my geographically most immediate circle of musicians, we investigated the possibilities by starting truly from the root of the matter: air, tubes, vibrations. Later: combining, applying, repositioning.
Radix was commissioned by the remarkably international Ensemble Schwerpunkt, with funds provided by Madetoja Foundation (Madetoja-säätiö) and Swedish Cultural Foundation in Finland (Svenska kulturfonden). It is dedicated to the members of Ensemble Schwerpunkt: Janne Jakobsson, Matthew Brown, Cecilie Marie Schwagers, Mikael Rudolfsson, and Matthew Sadler.
