Swedish composer (OM 18) writes, "Sinew0od for Paetzold contrabass recorder and electronics is a complex feedback network that the performer interacts with in different ways. The inner resonant frequencies of the contrabass recorder are amplified by means of electronic feedback. These resonances are influenced by played notes, key clicks and breathing, but also stimulated by sinewaves, injected inside the instrument with the help of two small modified speakers."

Listen to Petersson's piece Sinew0od performed by Anna Petrini (Paetzold contrabass recorder) at the 18th Other Minds Festival in 2013.
