Terence Dennis is widely regarded as one of New Zealand's finest musicians, and has an international reputation as a highly-sought accompanist. His performances throughout New Zealand and overseas have received high acclaim, and he regularly partners leading resident musicians and distinguished visiting artists in recital and recordings (German cellist Maria Kliegel, American violinist Ian Swenson, American soprano Alessandra Marc, American mezzo-soprano Kathleen Kuhlmann, Scottish soprano Margaret Marshall, British mezzo-soprano Sarah Walker, and the German baritone Eike Wilm Schulte.)
Terence Dennis has taught in masterclasses in Australia, Japan, Korea and Taiwan and since 1991 he has been the official pianist for the finals of the Mobil Song Quest.
Students enrolled in piano performance courses pursue a graded repertoire and technical regime from baroque to contemporary styles. Many of Terences students have achieved high success in tertiary training in New Zealand and abroad, and have been prizewinners in all the national piano competitions.
