Bach's sacred cantata, Gottes Zeit ist die allerbeste Zeit BWV 106 (Actus tragicus), composed in Mühlhausen, was likely intended for the 1708 funeral of Adolph Strecker. Though Bach's original manuscript is lost, a copy titled Actus tragicus survives, created by Christian Friedrich Penzel in 1768. The cantata explores themes of death and finitude, featuring a symmetrical structure around a turning point. It was published in 1876 as part of the Bach-Gesellschaft-Ausgabe. This piano transcription predates the more famous ones by composers like Busoni and Siloti, showcasing Fanny Mendelssohn's innovative ideas and placing her work ahead of its time.
