The composition Co - wie Kobalt, music for double bass and big orchestra is inspired by the element "cobalt", found in life saving or useful products (f.e. vitamin B12 or in different colours) as well as in deadly chemical combinations (f.e. in the atomic cobalt bomb); it is also inspired by the poem Agglutinati all´oggi, written by the Italian poet Giuseppe Ungaretti (1888 - 1970), that lays a formal and rhythmical foundation (basis), transforming the Italian text into morse codes of various durations. The double bass as a still dispised solo-instrument is mostly "singing" in very high regions of pitches, produced by natural and artificial harmonics, being accompagnied and/or commented by the orchestra.
