Between 1995 and 2003 the composer York Hí_ller from Cologne created 14 highly demanding piano pieces which are not only tone pictures, but also compositional reflections on persons personally close to him. They are 'monograms' because Hí_ller often chooses the tone letters of the dedicatees as a basis of his tonal form. Thus, thoughts of the composers Karlheinz Stockhausen, Hans Werner Henze and Pierre Boulez for example become aformally powerful, sometimes pensive dialogue by means of internal conn ections, and the last movement 'Scanning' with its combination of all these thoughts becomes a real finale.
