Sound Feedback Music is an 8 channel musical composition consisted of sound frequencies in a form of standing waves found in a closed space. Research of the relations between time and space is where I discovered the musical potential of the architecture. The methodology for detecting the sound frequencies of a particular space is based on scientific analysis of standing waves. They are a physical phenomenon which range and position depend on the dimensions, shape, and material of the closed space. By using the positive sound feedback technic I can detect their positions and range by moving through space.
