Carnegie Hall has some great online videos of piano and string quartet masterclasses and learning sessions.
The first video is a Masterclass with Leon Fleisher. Students in this class perform the late Schubert Sonatas. When you “Launch the Guide” you can choose to either watch the entire masterclass or just choose the technique that you want to see discussed. Techniques include:
- Practice Methodologies
- Macro vs. Micro
- Espressivity
- Dynamics
- Basic Techniques
- Arms and Fingers
The second masterclass/online learning guide is a discussion with the Emerson String Quartet about the Bartok quartets. The performances are inspiring and the discussion about the quartets is thought-provoking and good for all musicians, and especially for those performing the quartets.
