Double Concerto (Henze)

Henze's Double Concerto was commissioned by Paul Sacher and his Collegium Musicum Zürich and is dedicated to him and his wife, Maya Sacher, like Henze's Sonata per archi.

[1] It was finished in 1966 and was premiered on 2 December 1966 by the Holligers as the soloists and Sacher conducting his Collegium Musicum Zürich.

[2] The concerto is in one movement which has a total duration of approximately thirty minutes.

[1] In recordings, the tracks are usually divided according to this structure: Since this is a concertante piece, it features many technical challenges, such as double harmonics, flutter-tonguings, microtone glissandi and the so-called circular breathing, a technique which was fairly recent at the time.

For Henze, it is important to have a decorative contrast in instrumentation such as the harp, since "the distinctive oboe timbre can exhaust the listener if overdone".
