He grew up listening to the Alban Berg Quartet and the Amadeus Quartet, but at the moment, he says, his "absolute favorite group" is Quatour Ebene of France.

"Their complete Beethoven string quartet Album is simply stunning", Yu says.

Unlike a symphony orchestra, a chamber music group can be played anywhere-"it can be at the 2,800-seat-Carnegie Hall, or at someone's living room", Yu says.

It is much easier for chamber musicians to connect with the audience in live concerts because it is much more intimate compared to symphonies, he says.

Yu, one of the Mila quartet's teachers, says the group hardworking and professional.

"Even though they are still new as a string quartet, they have made rapid progress in a short time. They devote themselves to a lot of practice and rehearsal."

MILA Quartet has obtained a contract with Wu Promotion, one of the major agent companies in China promoting classical music, which is supporting their current tour.

"Such tours give young artists an incredible opportunity to engage with audiences in live concerts," Yu says. "I'm proud to be their teacher."
