Emanuel Bachʼs character piece "La Caroline" (Wq. 117-39) is an accessible and charming work included in the 1765 collection of character pieces. It is set in G major and is characterized by its lively rhythm and bright melody. The title suggests a specific person or intimate sentiment, and the piece exudes a warm atmosphere throughout. Within its concise structure, it incorporates delicate ornaments and nuances of the empfindsamer Stil. Performers are required to have flexible technique to express both the lightness and emotional depth of the piece.
