This piece is a romantic transcription of Schubert's famous lied, re-imagined as a display of piano color. Loder imbues the work with rich textures that highlight the delicate, avian character of the original melody.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing.

Developing a singing tone that carries through the surrounding filigree is the primary technical hurdle.
