I disagree with you, the student does sound excellent and is well prepared! Kashkashkian just has such a large resonate sound and helps guide the ear with excellent direction.
Maybe what you were expecting to learn is way below the level that you see here. She is also not in a performer role here so the focus is different, she is a high level teacher.
@@Ro3581 you are right,"but", I also would think, she has an "excellent Instrument ", than the Student has, his is not bad, buuut: she as the "famos Violist like Tabea Zimmermann, Nobuko Imai, Yuri Bashmet" has an "help Foundation of top Instruments". He certainly needs to continue studying,but is doing it really good, Chapeau!!!
