Evaluation criteria table.

Index	Metrics	Formula
Accuracy	The accuracy measurement standard refers to the ratio of the number of correct music types to the number of all music types [24]. The larger the index value, the more accurate the recognition result
Recall rate	The recall rate standard refers to the proportion of the theoretically largest number of hits that recognize musical characteristics [25]. The larger the index value, the more accurate the recognition result
F1 measurement	The F1 measurement index can effectively balance the accuracy rate and the recall rate by favoring the smaller value. The larger the index value, the more accurate the recognition result
