In this video, Zoltan Kocsis comments on the last movement of Beethoven's Sonata No. 18 the projection of the sound in sforzato and forte, the importance of certain notes depending on if they belong to the melody or if they are pedal notes, a more marcato or 'alla italiana' articulation, etc.
Afterwards, they work on issue related to the dynamics, accents, and the metrical freedom or rigor. The professor also explains that he should not use the pedal in some 'non legato' parts and points at the climax of the melody.
