Download the Program Notes! Revered German conductor Christoph von Dohnányi leads the BSO in two consecutive weeks of programs this season. The first features beloved pianist Emanuel Ax in two works-Mozart's Piano Concerto No. 14 in E-flat, composed in early 1784 as the first of the dozen piano concertos dating from the height of his popularity in Vienna; and Richard Strauss's Burleske, a sparkling, classically stylish early work composed when he was twenty-one. The program opens with the lovely Sextet for strings from Strauss's final opera, Capriccio, and ends with Mozart's Haffner Symphony, which began life as a serenade composed for the Haffner family in 1782, then was turned by Mozart into a symphony introduced in Vienna the following year.
