The"Ending"of the Pitch Exploration of the Twelve Tone Equal Temperanment?——The Contribution and Limitations of the Pitch-Classset Theory
Pitch-classset is a new concept of music analysis theory in the 20th century.As an under-lying structural pitch element,it exists in all kinds of music.Especially,pitch-classset play as an obvious structural role in modern non-tonal music gradually.It even becomes an independent struc-tural element in non-sequential atonal music.Therefore,the Forte's pitch-classset theory is of great signicance to both music composition and music analysis.Based on the evaluation of Forte's theory upon the historical view,which aim to present its innovations and limitations,the article proposed the concept of"Ending".The"Ending"does not refer to the end of the twelve-tone pitch system for all kinds of analysis and composition,nor the 12 chromatic-tones techniques,but rather to the way of thinking that takes the equal temperament system as the only principle and guideline.
