Although the results suggest that human-composed music received higher ratings
than the proposed model in terms of quality, groove, and coherence, the subjects
perceived greater creativity in the music generated by CRG. It is a valuable tool
for arrangement or style transfer. Furthermore, the CRG’s ability to generate creative
responses can potentially inspire and complement human creativity during the composition
process.

It's evident that every type of knowledge plays a part in performance improvement. Notably, knowledge candidates sharing similar composition attributes
seem to exert a more pronounced influence on enhancing model performance compared to the remaining knowledge types.
