Acumayá was initially a series of miniatures focusing on timbre, texture and the control of register. Initially, each movement started exactly the same and went on different directions. This quickly evolved into pairing some movements together so they would share the same material whilst still retaining their own character (i.e. thematic or rhythmic). Acumayá is a 5-movement work. The fourth movement is the longest (7min) and the second is the shortest (30s).
In the first and fifth movements, the cello has a melodic line that is coloured by the rest of the quartet. The third movement explores the idea of the quartet as one instrument capable of highlighting the complexity of a pitch through harmonics. The second and fourth movement are highly rhythmic exploration of the large register of the string quartet.
