In fractal geometry there exists a particular formula, the ‘logistic equation,’ which produces wonderful chaotic patterns whose character can be changed dramatically by varying a value called lambda. I discovered this piece in the region between lambda = 0,9 and 0,901534, hence the title. The notes, rhythms and overall structure were determined entirely by the equation which is audible through changes in dynamics and orchestration.
