George Benjamin's Fantasy on Iambic Rhythm (1985) for Solo Piano.
Published by Faber Music.

'This Fantasy takes Iambic rhythm (short-long) as its starting point. Various contrasted types of music evolve from this rhythmic “cell”, and are transformed and juxtaposed throughout a wide range of moods, often at great speed. A slow, gentle melody interrupts at a climatic moment and spreads resonantly across the complete range of the piano, before the final build toward a jubilant conclusion.'

~ George Benjamin

'...were not just impressive: they seemed to enter the repertoire before one's very ears.'

~ Paul Driver, The Sunday Times, 9th of February 1986
