Description:The changing role of a great orchestra in the total musical life of the community is the theme of Dr. Arian's remarkable and, indeed, unique study of the administrative problems of the Philadelphia Orchestra. As both musician and specialist in organizational behavior, Dr. Arian describes the development of the orchestra by Leopold Stokowski into an incomparable musical instrument, the financial problems it faced, the temporary resolution of these problems by a process of bureaucratic compromise, and the frustration of many of the orchestra's larger musical possibilities by the very compromises designed originally to ensure its sability.
