Professor Arad gives a general explanation about the piece and the student's performance. Specially, it is interesting to keep in mind the idea to adapt themselves to any situation while playing, and not to do the same thing automatically because they have internalized the process.
Arad explains the period and the spirit of the Romanticism. They work on the tuning about the two instruments (viola and piano). The Professor treats the relation between tuning and sound and gives an explanation about why tuning the viola with A string (and not with the rest).
They also works on general aspects, such as phrasing, position (left hand), color of sound, character, bowing, dynamics (balance with the piano) and articulation.
