Tonal consonance theory assigns a level of dissonance to any pair of pitches played simultaneously. This theory connects timbre with tuning and proposes that tunings must use local minima of dissonance. The timbre of the marimba de chonta produces a broad minimum, a sharp maximum, and some sharp minima of dissonance. Here we show that the combined effect of the traditional tunings and the musical practices of this instrument only allows the use of the broad minimum, leading to special features of this music as a transposition practice that keeps geometrical distances instead of musical intervals.

马林巴德琼塔音乐中音乐练习和调音之间的相互作用

音调协和理论为同时演奏的任何一对音高分配了一定程度的不协和。该理论将音色与调音联系起来,并建议调音必须使用不和谐的局部最小值。marimba de chonta 的音色产生了一个广泛的最小值、一个尖锐的最大值和一些尖锐的不和谐最小值。在这里,我们展示了传统调音和这种乐器的音乐实践的综合效果只允许使用广泛的最小值,导致这种音乐的特殊特征作为一种保持几何距离而不是音程的移调练习。
