Akosuen  /aa-KÅŒZ-eh-win/ is a music and performance project by Billie Howard involving sounds that focus on breathing cycles, chronic pain, and mediation on both quiet and extremely loud sounds.

Billie appears on her primary instruments: violin and piano, as well as with an ensemble including expanded strings, voices, organ, and percussion. In 2022, Akosuen completed TRILOGY, three sets of pieces written for her primary instruments. Other releases include duos with Rebecca Himelstein, supercollider, and Cinchel, guitar and electronics, and the sound installations We Do What We Can, and A Memory Palace of Fear.
