Chapter 7 examines music in model jingju, the dimension that has been generally acknowledged as the most successful among these productions’ artistic aspects. The author approaches music in model jingju from four perspectives: (1) orchestra organization which features a Chinese-Western combined orchestra, realized through artistic experimentation in the use of instruments, orchestral composition, orchestral conducting, and playing techniques; (2) percussive music, the innovative adaptation of traditional percussive passages, and the creation of new percussive passages to accompany arias, movement, and combat; (3) instrumental music and its functions in building up theatricality; and (4) vocal-melodic music, its association with traditional modes and modal composition, traditional metrical types and metrical-type composition, and traditional melodic-phrases and melodic-passage composition. This chapter features a detailed analysis of the use of musical motifs and personal interviews with chief composers and instrumentalists.
