"First, it doesn't surprise me that traditional music has experienced a kind of exhaustion in the 20th century - not forgetting that many musicians started to look outside the traditional structures of tonality"

This quote by Pierre Schaeffer talks to the exhaustion of conventional music in the 20th century. He acknowledges that numerous musicians began to look beyond the standard structures of tonality, which is using notes and chords to produce a melody. This shift far from conventional music was most likely due to the emergence of new technologies and the impact of other categories of music. Schaeffer's quote suggests that traditional music had become stale and uninspiring, leading artists to explore brand-new noises and structures. This expedition of new noises and structures has enabled the advancement of brand-new genres of music, such as jazz, rock, and hip-hop. The exhaustion of conventional music in the 20th century has allowed for the development of these new categories, which have actually become popular and influential in their own right.
