We randomly selected 20 pieces of music generated by MuseCoco performed with piano and our model and created a survey. 

We then enlisted 16 piano teachers to evaluate which pieces resembled human-created music more closely. The survey options were `Music 1', `Music 2', or `Similar', where Music 1 and Music 2 were randomly assigned to either the MuseCoco generation or ours.

e.g., 
1. Which music is more like human creation?
