"Christoph Schiller was born in 1963 in Stuttgart. He studied fine arts at the Kunstakademie Stuttgart and HfBK Hamburg. He later studied piano with Daniel Cholette and music theory in Basel. He has been playing concerts of improvised music on piano since 1987. In recent years the piano has been abandoned in favour of the lighter spinet, for which he has developed specific playing techniques which are influenced by inside piano techniques. Besides keyboard instruments his work with the voice has become increasingly important. He lives in Weil am Rhein and Basel."
