(b Passau, April 1690; d Vienna, 9 Dec. 1770). German composer, the son of Georg Muffat. A protégé of Fux, he worked in Vienna as organist to the imperial court, and from 1717 gave musical tuition to the royal children, including Maria Theresa. As an esteemed continuo player he was much in demand at the court chapel and theatre. His keyboard works include 72 old-style fugal versets (1726), 32 ricercars (before 1733), modelled on those of Frescobaldi, and 24 organ toccatas which call for virtuoso keyboard skills in performance. Most advanced in style are his six French suites for harpsichord (in his Componimenti musicali, c.1739), couched in the galant manner of Couperin, with titles for individual movements.
