CINCINNATI (AP) -- A piece of music commissioned by 27 orchestras premieres here today, performed by the Cincinnati Symphony conducted by Jesus Lopez Cobos.

Unlike many new pieces of music, "The Millennium Fantasy for Piano and Orchestra" won't just be played once and shelved. During the next two seasons, all 27 orchestras that formed the Millennium Commissioning Project and commissioned "Millennium Fantasy" will perform it.

The composer is Ellen Taaffe Zwilich, who won the Pulitzer Prize for music in 1983 for her Symphony No. 1.

The piano soloist is Jeffrey Biegel, who believes this is the largest number of organizations ever to combine to commission a piece of classical music.

Upcoming performances of "The Millennium Fantasy" through November will be in Rockford, III.; Westmoreland, Pa.; Rogue Valley, Ore.; Champaign, III.; Battle Creek, Mich.; and El Paso, Texas.
