-Based on the aforementioned raw dataset, we have constructed the `default subset` of the current integrated version of the dataset, and its data structure can be viewed in the [viewer](https://www.modelscope.cn/datasets/ccmusic-database/bel_canto/dataPeview).

-Since the default subset has not been evaluated, to verify its effectiveness, we have built the `eval subset` based on the default subset for the evaluation of the integrated version of the dataset. The evaluation results can be seen in the [bel_canto](https://www.modelscope.cn/models/ccmusic-database/bel_canto). Below are the data structures and invocation methods of the subsets.
