During recent years, Chinese composer Li Bo-Chan has been an active figure in the field of Chinese Orchestra in Taiwan and China, winning numerous awards of international composition competitions. In this thesis, I’d like to investigates his first piece of work composed for Pipa and piano, Late Autumn, commissioned in 2014 by Pipa performer Zhang Ya-Di for The Best of the Best Concert (BOB). This number is of arch structure with Coda part that creates beautiful melody and distinct use of chord comparing to other numbers of Pipa. The performer can thus communicate the sorrow and sentimentality of the departure of Fall through each note.

This thesis includes music analysis, interviews and musical interpretation. First, through collecting literature and interviews, I develop understandings of Li’s ideas of music composition and his philosophy of music. Then I utilize music analysis to examine the section and chord arrangement of Late Autumn to explore its aesthetics of music.
