This waltz is characterized by its flowing, expansive melodic lines typical of the late 19th-century salon style. It demands a expressive approach to phrasing and rubato.
At Henle 2 this is a beginner-level piece, where steady coordination between the hands is the main hurdle. The main demands: a waltz lilt that needs charm and a flexible left hand; sweeping arpeggio figures that must stay smooth across positions; and a true singing tone, with the melody floating above the accompaniment.
The challenge is to connect the wide-span arpeggiated figures smoothly without breaking the melodic flow.
