György Sándor Ligeti (May 28, 1923 – June 12, 2006) was a composer, born in a Hungarian Jewish family in Transylvania, Romania. He briefly lived in Hungary before later becoming an Austrian citizen. Many of his works are well known in classical music circles, but to the general public, he is best-known for the various pieces featured in the Stanley Kubrick films 2001: A Space Odyssey, The Shining and Eyes Wide Shut.
On August 15, 1962 Ligeti composed a symphonic poem for 100 metronomes set at random speeds, each wound to their maximum setting, then released all at once.
It’s partly an exercise in aural perception, as at first the sound is heard as white noise, but after a short time the brain is able to pick apart relationships between sets of metronomes set to similar speeds. As some metronomes stop ticking this sensation becomes stronger and your attention becomes drawn to the differences in phase between ticks.
Known as “Sound localization,” this is the same mechanism that allows you to focus your attention on the direction and source of one voice in a crowded room, ignoring noise considered unimportant by your brain
