Answer
Partch preferred to compose with scales dividing the octave into 43 unequal tones. This was in contrast to the traditional Western scale, which divides the octave into 12 equal tones. Partch believed that this system of equal temperament was unnatural and that it led to a lack of musical expression. He argued that his system of 43 unequal tones was more natural and that it allowed for greater musical expression.
