The general idea after the student's performance is to play more fluent - the flow always goes ahead- and the professor advises him to always follow the original manuscript. The professor gives indications about phrasing and articulation, about string crossing and shifting, and corrects the bow inclination - with a more circular movement of the arm.
Other corrections are dynamics, pitch duration, character, agogics, ornamentation, contact point with the string, and softer pizziccati - round position of the fingers. Moreover, the professor proposes the student to work on the bass register and points out the harmony that contributes to create a character of 'dramatic surprise' in a certain passage.
