Røshol - In a Matrix of Surrounding Space (2015)

IN A MATRIX OF
SURROUNDING SPACE
for three percussonists
«In a Matrix of Surrounding Space» (2015) was written for and premiered by the Norwegian percussion
ensemble SISU. The piece was written as a part of a project with SISU and nyMusikk komponistgruppe
(a group for young composers) that I was lucky to be involved in.
Using only non-pitched percussion instruments, grouped according to their materials of wood, skin/hide
and metal, and making the players switch between the different groups several times during the piece, I
was hoping to create and interesting effect that would conribute to general shape and movement of the
music in itself. Also, I have always felt that music for percussion has a more ritualistic element than other
types of chamber music and I wanted to embrace this and make it a important part of the piece.
Both the general structure and local rhythms was derived from a polyrhythm involving three different
strains of pulses, on for each player, that only converge once at the begninng and again at the end.
Between these two points there are a number of different textures, exploring all kinds of relationships
between the the three different players and their special rhytmic material and the instruments timbral
qualities.
