This version (S.309) is the first of Liszt's two settings of the poem, emphasizing a delicate, song-like simplicity. It is notable for the way Liszt uses the register of the piano to mimic the loneliness described in the text.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a true singing tone, with the melody floating above the accompaniment; chord voicing — bringing out one note inside a handful of others; and careful pedaling — clarity depends on the foot as much as the fingers.
Beyond that, expect several simultaneous layers, each needing its own dynamic level.
Achieving an even, singing tone throughout the melodic lines is essential.
