“Nine by Five” is named for a technical detail that appealed to Mr. Carter as an engine for this score. He wanted to take advantage of the instrumental doublings that wind players typically handle. So the flutist, Carol Wincenc, also played the piccolo; Mr. Neidich used two kinds of clarinet; Stephen Taylor doubled on oboe and English horn, and Marc Goldberg switched between bassoon and contrabassoon. The hornist, William Purvis, had no natural doubling (though he played with and without a mute); so all told, the five musicians played nine instruments.
