Beethoven’s five completed piano concertos – the C major op. 15, the B flat op. 19, the C minor op. 37, the G major op. 58 and the “Emperor”, in E flat major, op 73 – were composed between about 1793 to 1809. In this respect they differ from the quartets or symphonies or piano sonatas, all of which span the entirety of his compositional career. With his increasingly debilitating deafness, as well as changes in public taste and his own position in the complex musical world that was Vienna in the first quarter of the nineteenth century, Beethoven seems to have turned away not only from the genre but also from self-representation as a soloist on the concert stage. Nevertheless, the concertos were recognized early on as among his most important works.
