Raymond Murray Schafer has passed away following a battle with Alzheimer's disease.
Schafer will be primarily remembered as having founded the field of acoustic ecology — which examines the relationship between human beings and their sound environments. He popularized the term "soundscape" in his 1977 book The Tuning of the World.
Much like Webern and Cage, Schafer believed there was no such thing as pure, unadulterated silence. He came up with a concept called "sound walks," in which a listener would walk around their city with the aim of focusing on the immediate sonic environment and facilitating deeper listening.
As a composer, he wrote in many different genres. He had a particular fascination with the voice, and many of his works are for choirs of varying types. Schafer's scores often used a recognizable graphic notation.
In addition to these activities, Schafer was a passionate educator. During the 1960s, he produced a series of books and pamphlets that aimed to re-conceptualize the way that children learn music. He proposed that music pedagogy should focus on fostering creativity by centering composition and sound-based exploration, instead of merely teaching pieces by rote.
Our condolences to Mr. Schafer's family, friends, and colleagues at this time.
