Supposed Spaces explores the intersection between music and architecture. The work aims to evoke a journey through an imaginary building with various extraordinary rooms, hallways and spaces. As the piece unfolds, we discover new musical rooms, but also return to previously explored spaces to experience them from new perspectives, in different lighting, or with more or less activity occurring.Many composers have written music inspired by architecture. I am interested specifically in the similarities between a physical architectural experience and an abstract listening experience. Supposed Spaces creates relationships between characteristics of imaginary rooms and musical qualities, so that the work might evoke these fantastical spaces as vividly as possible. Each room is defined by a general atmosphere (hushed, dark, joyous, manic, still, energetic, etc.), but also by more specific elements: room dimensions, amount of light in the room, function of the room, etc. These attributes are translated into music, generating unique structures for organizing rhythm, pitch and other musical qualities. Also pivotal to the work is the way in which we move from room to room. The work explores a number of possibilities for transition, and also plays with the speed that we move through this imaginary building.
