Sounds
These 声 can 不 be easily 描述 by 标准 音乐 记谱法 They are more 复（杂） with interesting 质地（纹理、织体） and 属性
音乐 音符 are a very 纯 种类 of 声 with a 清楚 定义 音高 and 时值
声 are 不 always so 纯 and simple in-fact this is one of the things that makes 聆听 to 声 so interesting!
不 Merely Notes
As the Japanese 作曲家 Toru Takemitsu wrote
“Music is 不 merely 音符 on paper It begins with an active 聆听 to 声 ”
