There are many distinctive features that define Peter Bruun’s musical language: richness of sonority, supple rhythmic development, stylistic flexibility, imaginative and unusual instrumentation, pluralistic thinking, tonal melodies, repetition as a form-constituting factor and displacements of particular recurring patterns. The last two features give the music an expansive temporal feeling, an experience of existence amidst sheets of sound or music as a state of being.

Peter Bruun studied philosophy at Aarhus University from 1989 to 1991 taking private lessons in composition at the same time with Niels Marthinsen. He subsequently studied at the Royal Danish Academy of Music in Aarhus with Karl Aage Rasmussen, Per Nørgård, Hans Abrahamsen and Bent Lorentzen.

In 1996 he was granted the Three Year Work Grant from the Danish Arts Foundation. In 2000 he received the Wilhelm Hansen Composers' price. And in 2008 he was awarded tne Nordic Council Music Price for the chamber opera Miki Alone.
