|The Plain of Grasses and Sapphire
The Plain of Grasses and Sapphire are the orchestral work intending to describe the natural scene by music. Therefore, the elements used in these works are derived from the sound analysis of sound in their natural environments, such as wind, rain, thunder, and the twitter of birds.
Another concept of this work is to treat music as information which has grammatical system. The term "grammatical system" here is derived from the idea that some of the aspects of tonal music have grammatical feature. Although some of the elements are derived from natural sounds, therefore, they seem to be similar to the sound of tonal music as well.
