The Army School of Music is an established, albeit small, component of Irish musical life. It is currently recognized through its four constituent military bands which make their contribution to the Defence Forces and the state much in the manner of bands in other European countries. Notwithstanding this, the institution, which encompasses the majority of musical agencies in the army, retains the original title although the school referred to is now a remote element. But the retention of the title reveals something of the ambitious concept which prompted its creation. This dissertation seeks to trace the formation and evolution of the Army School of Music, and to account for its early in itiative and the reasons underlying the abatement of its influence. A brief review of music in Ireland at the turn of the century is provided to set in context the school's creation. Likewise, attention is devoted to the growth of the band movement, and the Irish position is contrasted with that of other European countries, most notably Germany whence hailed the first director of the school, Wilhelm Fritz Brase. There is a detailed exposition of the enterprising objectives set for the institution at its inception. The significant contribution made by the school and its individual members to broader musical activity and Irish music is also recorded.
