Dataset Card for Erhu Playing Technique

The original dataset is sourced from ErhuPT and all performances are conducted by professional erhu players. These clips are categorized by annotators with proficiency in erhu performance into 11 classes, namely: split bow, pad bow, overtone, legato & glissando & slur, strike bow, plucked string, throw bow, staccato bow, tremolo, and vibrato. For certain playing techniques, multiple audio clips are available, each played at different dynamics. This dataset was created and has been utilized for erhu playing technique detection. The label system is hierarchical and contains three levels in the original dataset. The first level consists of four categories: trill, staccato, slide, and others; the second level comprises seven categories: trill/short/up, trill/long, staccato, slide up, slide/legato, slide/down, and others; the third level consists of 11 categories, representing the 11 playing techniques described earlier.

After organizing the aforementioned data, we constructed the default subset of the current integrated version dataset based on its 11 classification data and optimized the names of the 11 categories. The data structure can be seen in the viewer. Although the original dataset has been cited in some articles, the experiments in those articles lack reproducibility. In order to demonstrate the effectiveness of the default subset, we further processed the data and constructed the eval subset to supplement the evaluation of this integrated version dataset. The results of the evaluation can be viewed in the erhu_playing_tech. In addition, the labels of categories 4 and 7 in the original dataset were not discarded. Instead, they were separately constructed into 4_class subset and 7_class subset. However, these two subsets have not been evaluated and therefore are not reflected in our paper. The following are the statistical charts for the 11_class (Default), 7_class, and 4_class subsets:

Dataset Summary

The label system is hierarchical and contains three levels in the raw dataset. The first level consists of four categories: trill, staccato, slide, and others; the second level comprises seven categories: trill\short\up, trill\long, staccato, slide up, slide\legato, slide\down, and others; the third level consists of 11 categories, representing the 11 playing techniques described earlier. Although it also employs a three-level label system, the higher-level labels do not exhibit complete downward compatibility with the lower-level labels. Therefore, we cannot merge these three-level labels into the same split but must treat them as three separate subsets.
