This piece is an alternative labeling of the first entry in the cycle, presenting the same contemplative musical material. It is distinctive for its minimalism and heavy reliance on color over complexity.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: chord voicing — bringing out one note inside a handful of others; careful pedaling — clarity depends on the foot as much as the fingers; and rubato that must breathe naturally without losing the pulse.
The primary focus should be on the resonance and decay of each chord.
