“The Evolution of Modern Orchestration” by Louis Adolphe Coerne is a book that traces the evolution of the orchestra and of orchestration in connection with the history of music proper. Special emphasis is laid upon what may be termed the “IMPELLING FORCES” to which the development of orchestration is due. In addition to extended studies of orchestral scores themselves, the standard works of Berlioz, Gevaërt, Riemann, Parry, and others have, as a matter of course, been referred to. Throughout the book, the achievements of the more prominent composers are set forth in such a manner as to indicate not only the distinctive features of their orchestration but their general creative ability as well.
