I loved this drama. The music gets a 10, of course. The music was amazing. The music makes you want to learn how to play an instrument if you don't already. Acting/Cast also a 10. I admit I watched this because of Jang Geun Suk, and he was fantastic. The viewer could feel his love of music through his performance. There was so much good acting in this drama that it is impossible to mention everyone. Kim Myung Min as Kang Gun Woo was the person you wanted to hate because of his abrasive attitude, but at the same time you couldn't help loving him and admiring his talent. All of the actors pretending to play instruments that they don't play in real life and doing it so convincingly was impressive. There were a lot of side stories in this drama, real life problems and struggles that keep people from pursuing their dreams. I would like to mention all the actors that I believe were amazing but that would take forever, so let me just mention one more..Hyun Jyu Ni as Ha Yi Deun (the flute player). I shed a lot of tears with her. She did a great job Rewatch Value..had to give this a 10 because I believe this is one of those dramas that you can watch over and over and get something new from it each time
