摘要

我们发展了一种在音乐作品中建立音乐模式的调性背景的方法。这随后被整合到音乐模式识别系统中。使用Krumhansl(1990)的寻键算法作为基础。它输出的最大相关序列用三次样条平滑，并用于确定感知和绝对音高误差的权重。使用统计上显著的最大相关性来创建分配的键序列，然后对其进行中值过滤，以改进键查找算法的输出结构。

Establishing the tonal context for musical pattern recognition

We develop a method for establishing tonal contexts of musical patterns in a musical composition. This is subsequently incorporated into a system for recognition of musical patterns. Krumhansl's (1990) key-finding algorithm is used as a basis. The sequence of maximum correlations that it outputs is smoothed with a cubic spline and is used to determine weights for perceptual and absolute pitch errors. Statistically significant maximum correlations are used to create the assigned key sequence, which is then median filtered to improve the structure of the output of the key finding algorithm.
