This tune is misattributed to Johanna Kinkel. She was a musician who composed a tune to her husband's (Johann Gottfried Kinkel) poem, "Des Lehnsmanns Abschied" or "Ritters Abschied", first line: "Weh dass wir scheiden müssen." Otto Plötz also composed a tune to this poem in 1859. Plötz's tune is used with Martin Meyer's translation of Kinkel's poem ("The Knight's Farewell," first line: "Hark! trumpets far off sounding") published by Root & Cady in 1863. It is the same tune used with the text "O Lord, Remember Me" adapted in 1873 by George Root in his The Männerchor
