Truth, goodness and beauty are the goals on the way to my compositional learning. However, the first two cover a very wide sphere which goes beyond the scope I can understand. As a result, beauty became the actual target at the present stage. To discuss the aesthetics of music, one should start from the materials and its structure. Too much interference from outside of music itself would make the discussion out of focus at this stage. Therefore, this thesis would take the construction of materials as the cornerstone, and use the practical works as the extension to help readers understand the relations between the works and its shaping process.

This thesis consists of three chapters. In the first,“The selection of pitch materials”, I discussed how I construct my own pitch language through the reflections of traditional tonal harmony. In the second chapter,“ Sonority”, I analyzed it with ADSR envelope in order to categorize their homogeneity and heterogeneity and, furthermore, to utilize the difference between them for making possible combinations and developments. In the third chapter,“ The analysis of the work”, I took “The Sounds from Late Night ”as an example to expound how pitch, rhythm, sonority and other musical parameters have been organized together.
