频谱形态 is an approach to 声音 材料 and 音乐 结构 which 专心 on the 频谱 of available 音高 and their 塑形 in 时间

The 概念 and 术语 of 频谱形态 are 工具 for 描述 and analysing 聆听 经验 The two parts of the 术语 refer to the 交互 between 声音 频谱 spectro- and the ways they change and are shaped through 时间 -morphology The spectro- cannot 存在 without the -morphology and vice versa something has to be shaped and a 形状 must have 声音 content Although 频谱 content and 时间 塑形 are indissolubly linked we need to conceptually to be able to separate them for discursive purposes - we cannot in the same 呼吸 描述 what is shaped and the 形状 themselves

Each 组成 of the 术语 belongs to other 学科 视觉 linguistic biological geological which is fitting since 音乐 经验 radiates across 学科

A spectromorphological approach sets out 频谱 and morphological models and 过程 and provides a framework for 理解 结构 relations and behaviours as experienced in the 时间 flux of the 音乐 源 - Denis Smalley 1986 Spectro-morphology and 结构 过程 in Simon Emmerson ed The 语言 of 电子声学 音乐 Basingstoke Macmillan Denis Smalley 1997 频谱形态 Explaining Sound-shapes Organised 声音 Vol 2 No 2 Cambridge Cambridge University Press
