Ach, es bleibt (Alto Trombone.Alto Voice.Organ) (The following aria, “Ach, es bleibt in meiner Liebe,” is from Johann Sebastian Bach’s Cantata: Du sollt Gott, deinen Herren, Lieben (BWV 77). It was intended to be a cantata to be sung on the 13th Sunday after Trinity. Although the text for the first movement of this work is taken from Luke 10: 27, the text for this particular aria is not biblical, but religious in nature, possibly based upon a text written by Johann Oswald Knauer of Schleiz for liturgical cantatas performed in Gotha between 1720-1721. Written for a large compliment of voices and instruments, the work was completed in Leipzig in 1723 and received its premiere also in Leipzig on August 22, 1723. The orchestration includes four vocal soloists (S A T B), chorus (S A T B), Tromba da tirarsi, Oboe I/II, Violins I/II, Viola, and Continuo. The six movements are as follows: 1) an extensive chorus for choir, strings, and tromba da tirarsi 2) recitative for bass soloist and continuo 3) aria for oboes, continuo, and soprano soloist 4) recitative for tenor soloist, strings, and continuo 5) aria for alto soloist and tromba da tirarsi 6) and a chorale for continuo and chorus. Bach’s usage of the tromba da tirarsi [slide trumpet] in this piece is unique, as it plays long melodic passages which are often pensive in nature, and not just notes played by the instrument to support the harmonic structure of the composition. As the tromba da tirarsi is played in manner similar to the trombone, that part was transcribed for alto trombone in this publication, and thus makes this very special gem available for a large audience on a very accessible and expressive performing medium.)
