Research On Superposition And Reduction Techniques In Heterogeneous Structures Of Homogenous Timbre

With the rapid development of technology,the production and application of timbre as a new idea has been applied by many composers in different fields.It has become an important and independent part of forming the compositions.Using the technique of timbre modulation as a clue and exploring the great possibility of changing the homogenous timbre by three techniques of superposition and reduction in heterogeneous structures of homogenous timbre of delay-type,cut-frequency,and acceleration-type for traditional national instruments such as Erhu and Pipa.With this brings new sparks to the timbres while enriching the creation space of national instrumental music.To further in his own "Chasing",these three techniques are used to adjust the pitch,amplitude,and frequency to obtain new sounds and to discuss the structural forces such as the expressiveness,over-convergence,and change reproduction of the sound effects created by the timbres in the works and upgrades the practical techniques at the operational level to the theoretical level.
