John Yaffé


For the past fifteen years, conductor John Yaffé has been a highly regarded member of New York City's musical community. He has conducted at Carnegie Hall, Lincoln Center, Symphony Space, and The 92nd Street Y, and has been lauded consistently by the New York Times and Opera News for his ability to inspire performances with "transcendent concentration, exemplary preparation, freedom, and commitment."

Yaffé was recently named Music Director Designate of the New York Contemporary Players, a new chamber orchestra devoted to the music of the 20th and 21st centuries. He recently led the Stuttgart Chamber Orchestra on their tour of the United States. Also in recent seasons, he led the Colorado Springs Symphony, Staten Island Symphony, Warsaw Philharmonic (at the Warsaw Autumn Contemporary Music Festival), San Antonio Symphony, Chattanooga Symphony, Chattanooga Opera, Walla Walla Symphony, and the Turkish State Opera. At the invitation of the American Embassy in Tirana, Albania, he led the first American musical ever produced in that country (West Side Story).

During his career, Yaffé was championed by several major figures: the great baritone Tito Gobbi, who invited him as musical assistant for his master classes in Florence, Italy; Julius Rudel, Music Director of New York City Opera, who invited him to join the company as an apprentice conductor; the legendary singer George London, who, after attending one of Yaffé's performances, invited him to join the staff at the Washington (D.C.) National Opera; and Leonard Bernstein, who was Executor of Marc Blitzstein's estate and entrusted Yaffé with revisions to Blitzstein's opera Regina. Engagements at the Wolf Trap Festival and with symphony orchestras and opera houses in Maryland, Connecticut, Michigan, California followed.

Soon after, Yaffé moved to Europe. He spent ten years as Répétiteur and Conductor in the German opera houses of Hagen, Münster, Osnabrück and Stuttgart. In addition, he served as Music Director of the Stuttgarter Operettentheater and was a guest conductor with the Städtisches Orchester Remscheid, the Südwestdeutsche Philharmonie, the Symphonie-Orchester Graunke of Munich, the Staatsorchester Stuttgart, the Stuttgarter Philharmoniker, and the Alt-Wiener-Strauss-Ensemble.

Joseph Leavitt, former Baltimore Symphony Executive Director, then brought Yaffé back to the USA to lead his burgeoning Florida Philharmonic Orchestra as its Resident Conductor. During his tenure, Yaffé conducted over 175 performances to critical acclaim.

Most recently, John Yaffé has served as Music Director of New York Lyric Opera Theatre (2009-10), New York's prestigious 92nd Street Y Symphonic Workshop Orchestra (1996-2009), Encompass New Opera Theatre (1996-2008), Centre Symphony (1999-2004), as a principal guest conductor at the Mannes College of Music (1996-2006), and as Co-Director of the Orchestral and Chamber Music Program of the Tanglewood Institute.
