Like many of Strauss's works, this waltz is defined by its sweeping, lyrical lines and sophisticated harmonic colorations within a traditional dance framework. It is an excellent study in melodic projection.
The technical difficulty lies in layering the cantabile melody over the varied and often syncopated accompaniment patterns.
Comparable difficulty and character — good candidates for what to learn next.
