The Kaikorai Valley College pupil plays piano at grade 8 level, clarinet at grade 7 level, saxophone, bassoon, bass clarinet, violin, guitar and sings.
He performs regularly on these instruments for the Southern Sinfonia Academy, the Dunedin Youth Orchestra, the Southern Youth Choir and many school ensembles.
But Corwin is not content with performing the works of some of the world's great composers for these instruments.
Instead, he has gained a name for himself in music circles for composing his own music.
Few secondary school pupils can say they have had their compositions performed and recorded by the NZSO.
Corwin has had two works recorded by the orchestra as part of the NZSO/Todd Corporation Young Composers' Awards.
He has also won the original composition category of the 2007 and 2009 New Zealand Community Trust Chamber Music Contest, won the Sheilah Winn Shakespeare Competition supreme award for composition, written a song with friends which was recorded on the 2007 Play It Strange CD, composed the music for the school's 2007 major production Copper, and had works performed by the Southern Sinfonia and the Dunedin Youth Orchestra.
Corwin is also a high achiever in the classroom.
He gained NCEA level 1 and 2 with excellence endorsements, he has been top of his year level since 2005, he has received Mana Pounamu Young Maori Achievers Awards for the past four years, and won the Dunedin-Otaru Sister City Society Japanese Speech Competition.
He plans to study music and Japanese at the University of Otago next year in the hope of becoming a film score composer or a Japanese translator.
Achievements: NCEA level 1 and 2 endorsed with excellence; Dunedin Registered Teachers Centenary Composition Competition winner (2005); NZSO Young Composers' Awards (2006-07 and 2009); Mana Pounamu Maori Young Achiever Award (2005-08); Otago Registered Music Teachers Secondary School Scholarship (2008); Cultural Blues (2007-08); Secondary School Chamber Music Composition Award winner (2007 and 2009).
Role model: ‘‘I like successful people who are humble.''
Hopes for the future: To study music and Japanese at the University of Otago.
