This piece draws upon 18th-century stylistic tropes filtered through a 19th-century lens. It is distinguished by its light, courtly character and decorative writing.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: ornaments that need to sound effortless, not squeezed in; precise articulation — the difference between crisp and blurred is the piece; and independent voices that must each sing on their own line.
Precision in the execution of baroque-style ornaments is essential for the style.
