The research objective is to study the influence of the social media platform TikTok on piano teaching, to compare the comprehensive piano level between students who use TikTok and students who learn normal teaching and to compare the comprehensive piano level between pre-test and post-test. The sample is 82 piano students and ten teachers from JiXiang Music School. Research tools such as tests and questionnaires were used in this study. The results show teachers' mixed perceptions of teaching efficiency and social media's role, alongside strong endorsement of traditional methods and teacher-student interaction for educational quality. Student outcomes were further contextualized through comparative experimental analysis. Students improved their knowledge level, the decrease in mean scores at the skill level may indicate a need for more practice or more effective teaching instruction in practical playing skills. The standard deviations before and after the experiment showed fluctuations in student performance, which may be related to students' study habits, teaching methods, personal interests, and other external factors. There was no significant difference between the pre- and post-experimental results of the knowledge and skill levels of the students in the two groups. Accept average of the piano comprehensive level of the TikTok post-test is equal to the average of the TikTok pre-test. The findings indicate that TikTok can enhance students' foundational knowledge and interest in piano, although it does not significantly contribute to developing their fundamental piano skills. Furthermore, the quality and accuracy of piano lessons available on TikTok may vary, posing a challenge for students to discern reliable sources. However, these concerns can be mitigated by incorporating TikTok as a supplementary rather than a primary teaching tool. This can help educators develop comprehensive and effective teaching strategies that integrate the strengths of both traditional and digital tools.
