Thomas Gorbach

The Variations are showing different transformations with ribbed sounds which originally come from a pianino turned upside-down. Various ways of working the piano strings were categorized befor the composing process started. During the work with sound transformations a classification system appeared that gives the work its musical form:
1st Variation: soft-sonorous amplification of the ribs in orbiting form
2nd Variation: sliding-down of ribbed sounds in combination with plane attacks
3rd Variation: Mixture of soft-sonorous and harsh rib-sounds with timevariations and plane attacks, forwards and backwards
4th Variation: rubbing on strings, scaled, backwards, fast-rubbed attack of strings
