Colors of Breath was my first attempt to compose for concert band. In this piece, I tried to put forward every sections of the wind orchestra in order to obtain some interesting instrumental colors. The form of Colors of Breath is as follows: after the introduction, the musical elements of a pop-rock song (i.e. verse, pre-chorus and chorus) can be heard in the right order but are interrupted several times by a slow theme which completely changes the character. Thus I wanted these two different atmospheres to coexist in the best possible way.
