Originally, Heinz Holliger wrote this humorous, yet demanding study not as an independent showpiece or encore, but as a component of his Concerto für Orchester with the meaningful subtitle ‚con soli per tutti‘. It is effective as a solo piece or can be performed by an oboe duo – or even be combined with the drone of other instruments indicated in the musical text. Instrumentation: oboe solo or 2 oboes (ad lib. also oboe solo with a Bordun of 2 horns or 2 clarinets or 2 strings)
