Answer
"Der Einsiedler", composed in 1915, is a piano piece by Richard Strauss, part of his Op. 49 collection of short pieces. It is a tonal work characterized by its introspective and contemplative mood, created through the use of a slow tempo, a simple melodic line, and sparse accompaniment. The title, translating to "The Hermit", reflects the solitary and reflective nature of the piece.
