# Enhancing MusicGen with Prompt Tuning
## 4 Experimental Results
### Result
#### 4.4.1 CLAP Score  
For prompts containing traditional Korean instrument names, the proposed method produced music that closely matched the characteristics described in the text, with the largest improvement observed with the prompt \"Create a cheerful melody with the high-pitched kkwaenggwari,\" achieving a CLAP score increase of 0.3691 compared with the baseline and an average improvement of approximately 0.1270 in this category. Similarly, for prompts referencing traditional Korean musical genres, the proposed method exhibited substantial improvements, with the most significant enhancement seen with the prompt \"Design a variation based on the classic boheosa,\" achieving a CLAP score increase of 0.3941 and an average improvement of 0.1613 across all prompts in this category. In the remaining groups, while the average improvements were not as pronounced in the story-based prompts and traditional cultural theme prompts due to the dataset being biased toward genres and instruments, individual prompts containing Korean traditional vocabulary showed improvements (see Table 6).

In conclusion, across a total of 80 data points, the cosine similarity value increased by an average of 0.0752. The proposed method demonstrated the ability to address the limitations of traditional approaches by capturing the unique aspects of traditional Korean music, showing remarkable improvements, particularly in traditional Korean instruments and genres. By strengthening the semantic alignment between text and music, the proposed method broadened the possibilities for generating culturally enriched and contextually accurate music.
