For the second time, the 17-year-old has won the Chamber Music NZ Contest, this time with 57 Octaves Below, for piano, flute and violin.
The catalyst for the piece came from the deepest musical note in the universe which, according to the Guiness Book of Records 2005, is a B-flat, 57 octaves below middle C, he said.
"It is on the other side of the universe, several million light years away. Its pitch is a billion times lower than the human ear can detect, and is being propagated through a super-massive black hole.
"I thought that this was quite exciting and imagined how long a journey it would be, moving to the other side of the universe."
Corwin was influenced by New Zealand composers Gareth Farr and John Psathas and some of their pieces' busy rhythms, general loudness and complexity.
In the future, he would like to create scores for films.
"Film composing would be a dream job really, especially because I would be drawing on everything I have learned about music in the 10 years I have been paying attention to it."
He will come close to achieving this, having being selected as the pupil composer for the 2009 National Shakespeare Schools Production in September.
57 Octaves Below will be performed at the CMNZ Contest Finals in Christchurch on August 1.
