Repetitive music has often been negatively linked with Freudian thanatos. Theodor W. Adorno provides an example in his criticism of Igor Stravinsky, whose, "rhythmic procedures ostinato closely resemble the schema of catatonic conditions. In certain schizophrenics, the process by which the motor apparatus becomes independent leads to infinite repetition of gestures or words, following the decay of the ego." Similar criticism was levelled at Ravel's Bolero.
