Diffusion Two, a snare drum quartet, was composed as a sequel to Daniel Adams marimba quintet Diffusion One. The term diffusion is derived from the Latin verb diffundere which means "to spread apart". In Diffusion Two, all players begin with uniform rolls that are rapidly transformed into single-stroke contrapuntal passages. This piece concludes with a polyrhythmic coda in which the snares of all four drums remain in the off position as occasional rim shots are interspersed within the complex texture.
