Mozart was so enchanted by his friend Anton Stadler that he wrote him both a full concerto and a chamber quintet for clarinet and string quartet. In January, join members of the Fort Worth Symphony Orchestra for Mozart’s Clarinet Quintet and Beethoven’s Piano Trio for clarinet, cello, and piano, a pair of works that showcase the clarinet’s agility and lyricality. Also on the program are Saint-Saëns’ Piano Quartet No. 2 and Haydn’s Divertimento à tre in E-flat Major.
