Professor Rizzi talks about Bach and Baroque music. It is very important to pay attention to all the hints that Bach gives in the score: slurs, articulations, etc. Although we have the idea that Baroque music is a very structured and logic style, we should avoid rigidity and severity within the form. The student has to distinguish between long and short lines with the phrasing.
The Professor asks the student if he knows other pieces or movements in which Bach uses the same melodic turns. The character is a little rude and the student plays too carefully. We have always to keep the flow while playing.
Talking about phrasing, there are different possibilities when we have 6 notes, e.g. 1-2-2-1. In other passages, the phrase should be organized in pairs.
