This piece by Tchaikovsky should be performed with a dancing (vals) and funny (scherzo) character, but the student makes it rather heavy and serious. That is why Professor Miriam Fried focuses on a lighter and more beautiful performance by the student. Down-bow is vertical and the rubato should be flow freer. Besides, the professor makes some corrections about phrasing, harmonic structure and chords. It is important to know the harmony of the piano in order to make decisions and show different colors. As a conclusion, Miriam Fried explains that the way to create emotion is by changing the bow speed.
