Under the coldest command, the most passionate performance begins.
South Korea's greatest stages are not completed by brilliant lighting or applause alone.
Behind the moment dozens of performers breathe as one to create a single piece of music, there lie hundreds of rehearsals and an obsession with perfection.
Yoon Sahyuk, the 7th Artistic Director and Principal Conductor of the Haewon Symphony Orchestra, is a conductor representing the domestic classical music scene.
After gaining recognition for her skills in Germany, winning European international conducting competitions, and serving as a guest conductor for major overseas orchestras and domestic ensembles, she was appointed as Artistic Director and Principal Conductor at a young age.
While everyone acknowledges her outstanding musicality and overwhelming leadership, her rehearsals are notoriously harsh. She does not tolerate mistakes, does not listen to excuses, and demands the same level of perfection from the members as she does from herself.
In the classical music industry, it is said that if you can survive Yoon Sahyuk's rehearsals, you can play anywhere.
At the nation's top orchestra, every season brings new performances, auditions, guest performers, soloists, and international exchange projects.
Numerous people gather with the same stage as their goal, and differing beliefs and musical interpretations constantly clash to complete a single performance.
