Firstly, they talk about the cadence: Prof. Arad suggests the student playing his own cadence because it would allow him to be more connected to the work. Professor Arad also mentions several cadences from other concert pieces and he tells a story about Penderecki. It is normal and not bad to get excited when you are going to perform in a concert.
About this specific piece, the professor corrects the fingerboard zone where the first chord must be played. He also recommends the student to play as a practice exercise the Caprice No. 24 by Paganini.
Afterwards, there are musical indications about weight, notes duration, tuning, character, sound quality and contrasts, dynamics or accents. Finally, Prof. Atar Arad insists on the issue of cadences composition.
