Translating to "rain pattering", German-born international sound artist Florian Wittenburg uses a MetaSynth and the Kyma visual programming language for sound design to emulate the sounds of rain pattering from aperiodic to periodic in two parts, along with heating noises in two parts, and a clock ticking; compellingly structured accompaniment to your personal ambiance.

Starting with a systematic variation of polyphony in each of the three movements of "Bis 4-Stimmung", German composer and pianist Florian Wittenburg deviates from strict structures through a component of randomly generated core notes which he then makes coherent through harmony and melody, each part punctuated with layers of Wittenburg reciting Dutch poet Cees Noteboom.

Using a metasynth, a software instrument that allows the user to draw or paint music, and a photograph of a small tree observed at a former train station in the German town of Kranenbur, composer Florian Wittenburg generates complex sound structures from the simple structures of the tree's branches used as a template for four rich sonic sketches.

Various facets of German composer and experimenter Florian Wittenburg's interests, in two iterations of two pieces and two compositions, using voice, vibraphones and ringing bowls, treated electronically to emphasize unique characteristics of sound from warmly rich to mysteriously fragile, balanced with space and careful timing; a valuable introduction to his work.
