Muzio Clementi was revered as ‘the father of the pianoforte’. He was a virtuoso, composer and teacher whose publishing and piano manufacturing made him hugely wealthy. Gradus ad Parnassum, in three volumes and completed by 1826, consists of 100 incredibly demanding exercises designed to lead to musical and technical perfection. It remains one of the great compendiums in musical history. Prizewinning pianist Alessandro Marangoni continues his critically acclaimed survey in this third of four volumes.
