Composed in 1915, it's the only Cello Sonata that Debussy left us. It expresses beautiful harmonic progressions and utilises a rich palette of different timbres. Peter Szabo comes along many topics recursively in the three tutorial, and the main goals are: 
1. Melodies on one string 
2. Fingers posture 
3. Technical problems solving 
4. Style for the Cadenza 
5. Balancing Piano and Cello
