On both the Schroeder #14 (Lee op. 70 #2) and the Bach Minuet #1 (Suzuki Book 2), the left hand technique is basically there, so I need to add the next layer. The next layer is conceiving of the entire piece and playing it through at a consistent tempo. Only then will I start to really hear the relationships between the parts. What I need to avoid is playing it like a series of excerpts. The same goes for my Arpeggio studies (A minor).
