A Pro-Life Stance Against Schopenhauer's Definition of Musical Abortions

" The departure from the arithemetical correctness of the intervals through some temperament, or produced by the selected key, is analogous to the departure of the individual from the type of species. The impure discords, giving no definite interval, can be compared to the monstrous abortions between two species of animals, or between man and animal" I was surprised by Schopenhauer's overstated oversight here. The intervals of keys are no more than a mathematical coincidence, a social construct, imposed by norms in composition and keys on a piano. He ignores a vast range of existing atonal music, the fact that different cultures recognize the existence of a different number of intervals (notes), and implicitly rejects the full range of the human voice, strings, and brass, which can play even the notes in between the frequencies we are accustomed to hearing. Proper tuning is an unquestioned assumption of many classically trained musicians that merely facilitates musical interaction, but it imposes a limit on the infinity of sounds and sound combinations that make music interesting. The Velvet Underground plays with vocals that shift between sustained notes and fluctuating speech patterns fading, singing just off key, which in our modern standard of over-production comes across as honest, authentic, and maybe even more Platonically true.
