A concerto for horn and orchestra, Explorations- Discoveries was composed in the early 1970’s at a time when the James Cook bicentenary was being celebrated. Just as the famous sailor explored and discovered, so to the composing of the work.
The work is structured in five interrelated sections contrasting fast with slow preceded by a slow introduction and concluding with a slow coda. All these sections orbit a central palindrome.
The horn is treated both lyrically and dramatically. Its music covers a wide range of pitch and dynamics and the instrument frequently is in dialogue with the orchestral horns.
Explorations – Discoveries was first performed in 1975 at a studio recording by the New Zealand Symphony Orchestra conducted by Alex Lindsay with Marcel Lambert as the horn soloist.
