The composition The Docks employs the horns of the ships, which are present in the harbour as its source. The individual parts are written in a simple graphic notation and designate entrances, durations and playing modes in minutes and seconds. Some improvising is required. Parameters of the composition are only durations, rhythms and density of the sounds of the ships' horns, bcause the pitch is defined by the ships and their crews who participate at the concert. 25 ships in the harbour of Kiel took part in the concert, the concert was broadcasted live from 12:05 to 12:30.
