摘要

Xa-lan是一个用Common-LISP编写的计算机程序，用于生成具有高水平符号/符号表现力的乐谱。一代是由旋律轮廓的音频分析驱动的。一旦旋律轮廓输入到软件中，原始轮廓的图形变换随机控制分数的不同符号元素。Xa-lan例程使用PWGL(一个基于lisp的可视化合成环境)的“表达符号包”显示它们的最终输出。Xa-lan可以通过算法生成一系列传统和非传统的音乐符号元素，为用户检索“随时播放”或完全表达的乐谱。

Xa-lan: Algorithmic Generation of Expressive Music Scores Based on Signal Analysis and Graphical Transformations

Xa-lan is a computer program written in Common-LISP to generate music scores with a high level of notational/symbolic expressivity. Generation is driven by audio-analysis of melodic profiles. Once a melodic contour is input to the software, graphic transformations of the original profile stochastically control the different notational elements of the score. The Xa-lan routines display their final output using the ‘Expressive Notation Package’ of PWGL, a LISP-based visual composition environment. A full range of traditional and non-conventional music notation elements can be algorithmically generated with Xa-lan, retrieving to the user a ‘ready-to-play’ or fully ex-pressive music score.
