If Joseph Haydn played a major role in the development of the symphony and string quartet, he was also and no less the virtual creator of the classical keyboard sonata. In wealth of musical invention and diversity of forms his sonatas surpass those of even Mozart and Beethoven. Although mostly less demanding technically, they are by no means easier to interpret. Their relatively modest demands in the way of virtuosity are more than made up for by the greater creative contribution they require from the player. Especially in the sonatas of his early and middle periods Haydn allowed considerable leeway to the interpreter in matters ranging from choice of ornaments to virtual invitations to interpolate free cadenzas. An intriguing challenge, but many pianists nowadays do not know how to cope with it. Schooled in later traditions, they cling to the printed text, never daring to make the contribution the composer took it for granted he could expect from the performer. Still, if Haydn placed considerable reliance on the player’s personal creative talent this never meant a blanket permission to alter the musical sense by changes foreign to the style of the time. In this release, legendary Viennese pianist Paul Badura-Skoda has recorded five piano masterworks by Joseph Haydn, on the occasion of the bicentenary of his death. His fortepiano from his own collection, which has been used for this recording and was built around 1790, is the most appropriate instrument available today for interpreting Haydn’s music.
