The Yangqin is one of the few musical instruments in Chinese music that is polyphonic, this characteristic allows the composition of music to develop complex thinking in the areas of tonality, musical form, melody and rhythm, harmony and counterpoint, and polyphonic texture, while also adding versatile artistic style to musical creations, bringing innovations and technical breakthroughs in contemporary music.

In this thesis, the Yangqin Concerto “Yuan” by Liang Han Kui is a recent composition that incorporates the four Yangqin hammers technique, which is not commonly seen in today’s Yangqin works and is a fairly new musical style. Elements from “Sentimental”, a pop music saxophone piece, are used as the musical motif while the four Yangqin hammers technique added in the composition has not been widely developed in contemporary pieces and there is even less academic research on it. The composer Ryan Zen’s Yangqin and piano duet “Frozen Fog” takes water as the theme and describes its natural characteristics in the three states of: solid, air, and liquid. The entire structure of the composition is created to the motif of triplets.

In summary, "Yuan" focuses on the four Yangqin hammers technique and polyphonic performance, while "Frozen Fog" explores performing techniques and interpretation. The aim of this research is to provide a valuable resource for future musicians and composers by offering a detailed analysis of these elements in the context of a specific genre.
