work in which Carter employed the technique. The mixing of chords with different root notes and the use of nested tuplets, both present throughout Sorabji's works, have been described as anticipating Messiaen's music and Stockhausen's Klavierstücke (1952–2004) respectively by several decades. Sorabji's fusion of tonality and atonality into a new approach to relationships between harmonies, too, has been called an important innovation.
