MUSIC

The New York Philharmonic has appointed David Del Tredici to be its new composer in residence for this season and next. Del Tredici, who will aid the Philharmonic’s music director, Zubin Mehta, joins the orchestra as part of the nationwide composer in residence program administered by Meet the Composer, an advocacy foundation for new music. The American composer is expected to compose a major work for the Philharmonic’s 1989-90 season and another for 1992. Other composers selected earlier for the program, in addition to Del Tredici, include: Los Angeles, Steven Stucky; San Francisco, Charles Warren; Chicago, John Corigilano; and, at the American Composers Orchestra in New York, Robert Beaser.
