Shifting currents in a stream, variations in the geometric shapes of flocks of birds in flight, changing weather conditions, cloud formations undergoing metamorphosis: these are patterns that are perceptible and expected but cannot be foreseen.
Similarly, auditory phenomena encountered while in transit through various environments and settings may be conspicuous as having these qualities, if one but takes the opportunity to listen.
Such inconstant elements are among the distinguishing features of musical arrangements in the transformation ambient mode. Along with the predominance of tones and textures, elusive turns and displacements in variable combinations of patterns contribute to the peculiar and perceptually striking nature of these works.
