Emanuel Bachʼs character piece "La Böhmer" (Wq. 117/26) is an elegant and lyrical work included in the 1765 collection "Character Pieces." It is set in C major and is characterized by its gentle and sophisticated melody. The title is believed to be derived from a specific person or theme, and the piece is notable for its intimate and emotionally rich expression. It exemplifies the Empfindsamer Stil (sensitive style), with inventive harmonies and ornamental notes used attractively within its brief form. Performers are required to have delicate skills to express the poetic nuances of this piece carefully.
