This version of Fumagalli's work emphasizes the lyrical potential of the piano as a substitute for the human voice. It is technically demanding in its requirement for precise phrasing and tonal color.
Ensure the rubato feels natural and supports the lyrical line rather than interrupting the pulse.
Comparable difficulty and character — good candidates for what to learn next.
