The score of Three Angels is a representation of sound and texture rather than a prescription of sound. The composition is similar to a painting, comprising of a background texture, percussive interjections and a solo voice.
All the parts in Three Angels blend into an overall texture:
The solo melody is more haunting and distant than prominent.
The multiphonics are vocal in nature, some delicate, others almost like subdued screams, contrasted with percussive interjections.
The saxophone parts guide the player: fingerings for the required techniques are shown along with conventional notation for the solo melody.
