The Researches On The Five-Degree Relation Of Piano Music C Omposition And Performance In China

The piano music with China's style has been developed based on traditional Western techniques with its strong influence in both composition and performance. Based on the comparative analysis of various editions of Running Water in Brooks and some other representative piano music works, the author of this dissertation finds that the Five-Degree relation, its extended Five-Tone features, identical Tong system and the melody and scale system in traditional Chinese music are the representative features of China's piano music. The Five-Degree relation is still an obvious exterior feature and of importance in some piano music combined with certain modern western techniques. As the base for the formation of China's piano music style, it is the main feature to distinguish from the traditional western major and minor keys. The formation of Five-Degree feature explained from the perspective of temperament of five degrees' mutual engendering offers theoretical referring evidence for the practical treatment of acoustics and tones' functional inclination. But it is still a long way to go for the practice. The practical performance is exactly the guidance for audial transformation through equal temperament replacing natural temperament and flexible performance techniques. The base of performance techniques theory is the relationship between the strength and distance to touch the keys and their transformation can widen the acoustic space during the recreation of performance. The performance features of the piano music with Chinese style is exactly the product of combination with Five-Degree features of composition in this space. It is mostly revealed in the emphasis of Five-Degree relation and softness of Three-Degree, comparing with the major-minor keys system.
