 ### 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.
