Spectres V – Diffusion

In a 1955 pamphlet entitled Seven Years of Musique Concrète, Jacques Poullin wrote:

[…] sound projection in a concert hall is a logical extension of the concerns of the Groupe de Recherches de Musique Concrète and requires its technicians to properly study multiple aspects of the problems of sonorisation that are often neglected and to date have been almost exclusively the preserve of ‘public address’ technicians.1

From the very beginning, fixed media electroacoustic music in its various guises faced a significant challenge: that of how it could be shared with the public. Even before it was distributed in the form of records, musique concrète, having first been transmitted on radio, soon turned to the concert stage. From the time of its birth, a twofold question was posed: What strategy of diffusion could be used for this music which involves no live performers? But also, how could it make use of existing systems of sound amplification without losing its singular nature, making sure to preserve its own particularities? Identified very early on, these questions have lost none of their pertinence some seventy years later.
