This is one of the early works by which the clarinettest Jörg Widmann also made himself a name as a composer. The form develops from the – at first only tentative – interaction of the three instruments. Sound-sensitive and eruptive moments alternate unexpectedly. Between 'jazzy-secco' and the 'Spieluhr' solo, the piano announces the passage of time: '12 Glockenschläge Mitternacht'.
