| 抄録: | Time-span tree is a stable and consistent representation of musicalstructure since most experienced listeners deliver the same one, almost independentlyfrom context and subjectivity. In this paper, we pay attention to the reductionhypothesis of the tree structure, and introduce the notion of distance asa promising candidate of stable and consistent metric of similarity. First, we designa feature structure to represent a time-span tree. Next, we regard that when abranch is removed from the tree the information corresponding to its time-span islost, and suggest that the sum of the length of those removed spans is the distancebetween two trees. We will show that the distance preserves uniqueness in multipleshortest paths, as well as the triangle inequality. Thereafter, we illustrate howthe distance works as a metric of similarity, and then, we discuss the feasibilityand the problem of our methodology. |
