-Firstly, **Fig. 1** illustrates the number and proportion of audio clips in each category. The category with the largest proportion is Upward Portamento, accounting for 19.0% with 536 clips. The smallest category is Tremolo, accounting for 8.1% with 228 clips. The difference in proportion between the largest and smallest categories is 10.9%. Next, **Fig. 2** displays the total audio duration for each category. The category with the longest total duration is Upward Portamento, with 14.11 minutes, consistent with the results shown in the pie chart. However, the category with the shortest total duration is Plucks, with a total of 5.06 minutes, which differs from the ranking in the pie chart. Overall, this dataset is comparatively balanced within the database. Finally, **Fig. 3** presents the number of audio clips distributed across specific duration intervals. The interval with the highest number of clips is 0-2 seconds. However, the number of audio clips decreases sharply for durations exceeding 4 seconds.
