The cast of Tomorrow's Cantabile keeps growing and growing, and now we have a first look at four members of Cha Yoo Jin (Joo Won)'s orchestra. 

First, we have Yoo Il Rak (Go Kyung Pyo) playing the violin. Yoo Il Rak is a freewheeling, outgoing character who thinks classical music is too stuffy and old fashioned. He only plays classical music to please his father. 

Second is Ma Soo Min (Jang Se Hyun), the master of percussion. He has a crush on Cha Yoo Jin, so he competes with Seol Nae Il (Shim Eun Kyung) for attention. Jang Se Hyun is a rookie actor.

In the next set of stills, we have Lee Yoon Hu (Park Bo Gum) as the star cellist of the group. A prodigy who graduated from Julliard, he almost quits because of a slump until he meets Cha Yoo Jin and Seol Nae Il.  

Last, but not least, is Choi Min Hee (Min Do Hee), who seems adorable, but still knows how to handle her giant contrabass. She has a unique, off-the-wall personality.
