本文提出了多时间尺度的可视化技术,用于显示密钥查找算法的输出。键图形的横轴表示乐谱中的时间,而垂直轴表示用于为键查找算法选择音乐的分析窗口的持续时间。根据输出键的主音高对每个分析窗口结果进行阴影处理。得到的曲线图可以用来比较不同时间尺度上的关键字查找算法之间的差异,并查看音乐作品中关键区域之间的和声结构和关系。
Multi-timescale visualization techniques for displaying the output from key-finding algorithms are presented in this paper. The horizontal axis of the key graphs represents time in the score, while the vertical axis represents the duration of an analysis window used to select music for the key-finding algorithm. Each analysis window result is shaded according to the output key’s tonic pitch. The resulting diagrams can be used to compare differences between key-finding algorithms at different time scales and to view the harmonic structure and relationships between key regions in a musical composi-
