A native of Bohemia, Leopold Kozeluch made his name in Vienna, a thriving musical center dubbed the land of the Clavier by Mozart. The sonatas in this volume all appeared in 1784, meeting the challenge of Mozart's popularity head-on. Kozeluch was singularly adept at producing what was considered the ideal fortepiano sonata of the time, his high reputation making him an influential supporter of a new instrument capable of accommodating the clarity, the delicacy, the light and shade he demanded in music.
