论文摘要
我们提出了一个新的系统，用于实时可视化音乐性能，目的地集中在弦乐四重奏中播放的赋格仪上。基本原则是提供视觉指南，以使用应尽可能吸引人，易于访问和有效的策略更好地理解音乐。与单独声音相关的音高曲线是在颞轴相对于度量位置进行标准化的空间上绘制的，并且相对于其主题和动机分类垂直对齐。与音调有关的方面也被代表。我们描述了我们开发的潜在技术和技术环境。特别是，该作品的节奏和结构表示依赖于使用在线动态时间扭曲的实时多形音频到得分对齐。可视化将在丹麦弦乐四重奏的音乐会上介绍，演奏约翰·塞巴斯蒂安·巴赫（Johann Sebastian Bach）的最后一件艺术品。
We present a new system for real-time visualisation of music performance, focused for the moment on a fugue played by a string quartet. The basic principle is to offer a visual guide to better understand music using strategies that should be as engaging, accessible and effective as possible. The pitch curves related to the separate voices are drawn on a space whose temporal axis is normalised with respect to metrical positions, and aligned vertically with respect to their thematic and motivic classification. Aspects related to tonality are represented as well. We describe the underlying technologies we have developed and the technical setting. In particular, the rhythmical and structural representation of the piece relies on real-time polyphonic audio-to-score alignment using online dynamic time warping. The visualisation will be presented at a concert of the Danish String Quartet, performing the last piece of The Art of Fugue by Johann Sebastian Bach.
