摘要

本文提出了一种基于Pantelis Vassilakis模型的粗糙度描述符的实现。我们将实现的描述符应用于György Ligeti的拨弦键琴连续谱(1968)的计算机辅助音乐分析。我们的分析建立了粗糙度模型、声质量组成概念和利格蒂的运动和渗透性音色概念之间的平行关系。因此，我们展示了连续体录音中存在的粗糙度的图形表示，提出了作品的形式分割，并从音乐学的角度分析了它的形式发展。

A Roughness Model Implementation to Analyze Sound Mass Composition: A Case Study in Ligeti’s Continuum for Harpsichord (1968)

We present in this paper an implementation of a roughness descriptor based on the model of Pantelis Vassilakis. We apply the implemented descriptor to perform a computer-aided musical analysis of György Ligeti’s Continuum for harpsichord (1968). Our analysis establishes a parallel between the roughness model, concepts of sound mass composition, and Ligeti’s ideas of timbre of movement and permeability. As a result, we display a graphical representation for the roughness present in the Continuum’s recording, propose a formal segmentation for the piece, and analyze its formal development from a musicological point of view.
