A timeless creation that marked not only the end, but also what might have been a new beginning, Beethoven’s quintessential Symphony No. 9 is his final complete symphony and the first to include voices in the popular “Ode to Joy.” Gabriela Lena Frank’s Pachamama Meets an Ode, composed in response to Beethoven’s First and Ninth—both on this evening’s program—serves as a perfect complement as The Philadelphia Orchestra completes its full cycle of Beethoven symphonies at Carnegie Hall.
