Franz Welser-Möst to Leave the Cleveland Orchestra

One night last fall, Franz Welser-Möst, the music director of the Cleveland Orchestra, walked onto the stage of Severance Hall, crossed over to the podium and faced the audience. He was neither solemn nor particularly expressive; he just flashed a Mona Lisa smile before turning to the players and gesturing the downbeat of a Mozart symphony.

For the regulars in the audience, this was a familiar sight. Welser-Möst, 63, is known more for his authoritative, even demanding, conducting than for his showmanship. And what followed that night was also familiar, as the orchestra turned out a program of the Mozart, a new percussion concerto and a Tchaikovsky rarity at the exhilaratingly high level that has led many to call this ensemble the finest in America.

Unflashy yet unmatched. Such is the culture of the Cleveland Orchestra, an oasis of excellence, maintained and nurtured since Welser-Möst became its music director in 2002. And while there is more to come — the orchestra opens Welser-Möst’s Perspectives series with a pair of concerts at Carnegie Hall on Jan. 20 and 21 — the end of his tenure is in sight: He announced on Thursday that he would not renew his contract when it expires in 2027, which is relatively soon given the far-ahead planning cycles of classical music.
