Revolutions in music and physics,1900–30

Abstract

The period 1900 to 1930 saw fundamental changes in the basic laws of physics. The discoveries of the special and general theories of relativity and those of quanta and quantum mechanics transformed profoundly physicists’ understanding of the nature of space and time, as well as the fundamentals of physics at the atomic level, which have no counterpart in classical physics. Almost coincidentally, major changes took place in the processes of musical composition – that same period seeing the development of atonality, the liberation of rhythm, and twelve-tone music. This essay reviews in non-technical terms the profound changes in the thinking of physicists and compares the intellectual struggles involved with the extraordinary parallel changes in the approaches of composers to musical composition. No causal connection is suggested, but the common theme of the processes of innovation and creativity within very strict sets of rules in both physics and music is emphasised.
