Chapter 8: Accretion -

for 3 pianos and a pianist

Accretion is a collaboration between pianist Magda Mayas and choreographer Toby Kassell. This project creates different spatial and aural perspectives, where sound and the memory of sound and gesture gain a spatial and physical presence. Three pianos are placed in different positions in the performance space, with the audience sitting in between and around the instruments. The pianist plays inside the instruments with various objects and preparations, moving between the pianos to perform the resonance of all three sounding bodies simultaneously. Small vibrating engines and Ebows are placed inside the pianos operated from elsewhere in the space through remote controls. The combination of these resonating materials form a sonic and physical connection between the pianos acoustically transforming the performance space.

Toby Kassell is a choreographer and dancer working extensively with sound and producing original pieces, currently employed at the Göteborg Opera.

I discuss the process of developing Accretion, gestural approaches in instrumental performance and movement as part of timbre orchestration in detail in chapter 8 of my thesis.
