After Cinderella and Prince Charming meet, Terra spots some Unversed on top of the balcony, overlooking the ballroom. As Terra travels up towards the balcony, he comes across an Unversed known as the Symphony Master.
The Unversed summons three massive instruments, a cello, trumpet, and drum, to attack Terra with their sound waves. After being hit by a resulting explosion of energy, Terra engaged the Symphony Master.
After a long battle, Terra was able to defeat the Symphony Master.
