The 'Württenberg' Sonatas are very demanding, clearly intended for skilful, professional keyboard players. The sonatas have almost symphonic or even operatic dimensions and attitudes; in fact they may almost be called romantic, conjuring up fantastic and colourful landscapes. The first three of the set are here performed on Bach's own favourite instrument, the clavichord, by Miklós Spányi, whose indefatigable work in bringing the keyboard music of C.P.E. bach to a wider audience has impressed both critics and music lovers alike.
