Recording with the Swedish National Orchestra Academy:

White light is composed of the continuous spectrum of all frequencies of visible light. To make this visible a prism is used in which the different wave lengths are refracted and thus all colours appear next to each other as in a rainbow.

Just as white light is made up of the continuous spectrum of all visible light, white noise is a continuous spectrum of (all audible) sound. But music consists not only of pitch, other parameters – such as rhythm, timbre, dynamics – are just as important for the musical result. Applying a prism in a musical context must therefore result in much more than just a glissando over the whole ambitus of the sound.

The initiation of PRISMA is white noise: A chromatic total through all registers of the orchestral instruments with every instrument individually repeating a small number of pitches at a different tempo. But what lies behind this energetic noise, which musical possibilities can be found in this undirected energy?

In several filtering processes different aspects of the initial sound like rhythm, timbre and melody are examined and developed. Coming from the original, chaotic noise, different stages of noise and clarity are discovered, displayed and combined.

This filtering process however overstrains the system. The filters begin to leak; holes, scratches and tears appear. Sounds that should have been erased by the filters get through the system and a background noise emerges which over time evolves and becomes more and more present. Simultaneously the filtering processes that happen in the foreground become unstable, disappear into the background noise which now has become the main focus, a new filter has emerged through the leaks that appeared in the system.

Concert with SNOA

SNOA, the Swedish National Orchestra Academy, has commissioned a piece from me which they are going to play on Saturday, the 28th of April 2012. The orchestra will be conducted by Roland Kluttig, GMD in Coburg. Apart from my composition, Salvador Brotons’ Percepcions percudides for percussion and string orchestra and Franz Schubert’s 8th symphony in C major The Great will be performed.

Update: The piece has now been finished. It is called PRISMA, more details can be found here.
