Stop and listen / let the sound surround you / hear how the time changes / what do you find in its folds?

Chro­no­va­ria­tions is a visual sound art piece which combines a sound installation and an electroacoustic experimental music concert. Every sound in the piece – even though some of them are heavily effected – originate from the acoustic sounds and special techniques of the tenor saxophone.

In the sound installation electromagnetic transducers convert industrial scrap metal pieces and thunder sheets into resonating speaker objects. The music explores resonance and spectralism with contemporary approach by the means of electroacoustic improvisation.

The name Chro­no­va­ria­tions is created to describe the themes and concepts presented and studied in the piece; time, timelessness, the subjectivity of the sense of time, erosion of memory and recurrence. The installation consists of a 20-voice aleatoric composition that works algorithmically, allowing up to 1950 different kinds of sonic results.

The piece strives for sensory-friendliness: the sound pressure of the music remains safe and moderate, sudden changes in lighting are avoided and bright lights will not be directed at the audience. We hope that the audience avoids strong fragrances. Sensory sensitivities are taken into account as well as possible, but participation is at your own risk. The space is accessible by wheelchair.

We are happy to answer any questions about the concert! More information about arriving at the Music Hall.
