Going in the desert and return with some new truth sounds very biblical, doesn’t it? Likewise in music such new ’truth’ can easily turn into new dogma and serialism certainly was a very strict and even dogmatic system. It became a sort of smokescreen for a whole generation of mediocre composers to hide behind. As long as you rotated your notes with the required serial pedigree you were accepted by academia as a worthy disciple, no matter how boring or ugly your music would sound. Anyone not committing to these lazy dogma’s was not taken seriously and ’cancelled’ as we would probably call it today. Thankfully strictly serial composers are mostly forgotten, while those who resisted the peer pressure and stubbornly developped their own musical language (while even adopting serial devices) are now the ones acknowledged as the true ’originals’.
Adorno put Schoenberg and Stravinsky against each other in an essay on modern music. In his dogmatic view Schoenberg represented the absolute musical truth, while Stravinsky was accused of going commercial by adopting neo classicism. After the powerful ’earthliness’ of Rite of Spring, etc. this stylistic change was felt as a betrayal. In his mind Stravinsky copped out and adopted the ’wrong’ conciousness. I’m not sure if Adorno ever wasted any words on Strauss, but if he had he would probably have condemned him for not having a conscience at all.
