(Isaac) Ignaz Moscheles (German pronunciation: [ˈig.nats ˈmɔ.ʃɛ.lɛs]) (23 May 1794 – 10 March 1870) was a Bohemian composer and piano virtuoso, whose career after his early years was based initially in London, and later at Leipzig, where he joined his friend and sometime pupil Felix Mendelssohn as Professor of Piano at the Conservatoire.
Among his 142 opus numbers, Moscheles wrote a number of symphonic works. Apart from an overture, a ballet and a symphony, all are scored for piano and orchestra: eight piano concertos (of which the last has only come down to us in fragmentary form, no orchestral parts having survived) and sets of variations and fantasias on folk songs. The main theme of the finale of his fourth piano concerto is based on the tune "The British Grenadiers". Moscheles also left several chamber works (including a piano trio that has been recorded), and a large number of works for piano solo, including sonatas and the études that continued to be studied by advanced students even as Moscheles's music fell into eclipse. There are also some song settings.
More recently, with the modest but noticeable revival of interest in compositions by this composer and those of his colleagues, more of Moscheles's works are being made accessible on compact disc, especially by small and independent record labels. All the completed piano concerti and fantasias for piano and orchestra are available on the Hyperion Records label, played by Howard Shelley, who also conducts the Tasmanian Symphony Orchestra; they have also issued the complete piano studies, played by Piers Lane. Ian Hobson has also recorded the first six, and included a pair of variations not recorded by Shelley.
