Professor Silverstein begins this masterclass with some explanations about playing on the beat and not before the beat, because in this way the chords would be divided. Joseph Silverstein shows it by playing and he points out that fingers should be placed sooner. He also plays the first measures from the Fugue (second movement).
Afterwards, they talk about the tempo: it is related to the movement between one harmony and the next one. Professor Silverstein also makes some indications about attacks, sound preparation, metrics and phrasing, among others.
