频谱形态 is an approach to 声波 材料 and 樂/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 经验 The two parts of the 术语 refer to the 交互 between 声波 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 樂/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 樂/乐 源 - Denis Smalley 1986 Spectro-morphology and 结构 过程 in Simon Emmerson ed The 语言 of 電聲學/电声学 樂/乐 Basingstoke Macmillan Denis Smalley 1997 频谱形态 Explaining Sound-shapes Organised 声波 Vol 2 No 2 Cambridge Cambridge University Press
