Studies began life as an aid in the struggle to master the piano within the human limitations of two hands and ten fingers. But from being the bane of many a pianist's life and a means of selling more pianos, these arid technical exercises flowered into some of the greatest music written for piano from Chopin, though Debussy to György Ligeti. And in Conlon Nancarrow's studies for player piano, they even inspired the greatest set of keyboard works beyond any human ability.

To find out how and why studies evolved to transcend their original function, Tom Service is joined by musicologist Katy Hamilton and talks to Pierre-Laurent Aimard who worked closely with Ligeti on his extraordinary series of studies, widely regarded as some of the greatest piano music of the 20th century.
