"Ein Mara weicht von dir" Stauffer, however, entertains the possibility that it may be new music. Osanna (da capo) As above. Agnus Dei Aria for alto in G minor with violin obbligato, no autograph tempo marking, time signature. Parody of an aria, "Entfernet euch, ihr kalten Herzen" ("Withdraw, you cold hearts"), from a lost wedding serenade (1725). Bach also re-used the wedding aria for the alto aria, "Ach, bleibe doch", of his 1735 Ascension Oratorio Lobet Gott in seinen Reichen, BWV 11; Alfred Dürr has demonstrated that Bach adapted both "Ach, bleibe doch" and the Agnus dei directly from the lost serenade's aria, rather than from one to the next. Four-part chorus in D major, no autograph tempo marking, time signature. The music is almost identical to "Gratias agimus tibi" from the Gloria. Recordings , 237 recordings are listed on bach-cantatas, beginning with the first recording by a symphony orchestra and choir to match, conducted by Albert Coates. Beginning in the late 1960s, historically informed performances paved the way for recordings with smaller groups, boys choirs and ensembles playing "period instruments", and eventually to recordings using the one-voice-on-a-vocal-part scoring first argued for by Joshua Rifkin in 1982.
