This practice-oriented course teaches arrangers the fundamental techniques: from preliminary considerations to score creation and notation of individual voices. Melody, harmony, rhythm, formal structure, and instrumentation are topics addressed in a way that allows them to be applied to personal projects without stylistic constraints and open to the development of individual ideas. Exercises and solutions make the book a compact course, inviting readers with explanations of technical terms as well as transposition and range tables for reference. "Arranging is problem-solving," as the arranger Richard Roblee once put it. This book prevents problems from arising in the first place.
