Professor Rainer Schmidt ponders on the tempo of this movement: maybe it is so fast because Mendelssohn was looking for a powerful and brilliant character, with large quantities of sound. Regarding the beginning, Schmidt highlights a change of articulation and he asks the students for playing with different vibrato quantity and speed to achieve the best effect.
Rainer Schmidt also talks about the type of articulation and phrasing, the tempo and the dynamics. Then, they focus on the sforzati in a certain passage and they work on it with detail.
After training in order to improve the rapport and bow issues, Professor Schmidt comments the difficulty of Mendelssohn's string quartets and he encourages the students to think about the way of achieving a better performance.
