The emphasis is on the practical fundamentals of orchestration. The Sixth Edition has been expanded and revised to reflect new developments in instruments and orchestral practice, and a new listening compact disc has been added that contains selected examples of orchestration. A listening compact disc features selected samples intended for use in conjunction with the book. New musical examples and listings, and an updated bibliography which includes many recent publications. A short chapter on scoring for high school orchestras, and information on nonorchestral instrumental groups, including the band and the wind ensemble.
