Singet dem Herrn ein neues Lied, BWV 190
' (Sing a new song to the Lord), ', is a church cantata by Johann Sebastian Bach. He wrote it in Leipzig for the New Year's Day and first performed it on 1 January 1724 as part of his first cantata cycle. He adapted it in 1730 to , for the celebration of the bicentennial of the Augsburg Confession. History and words. Bach wrote the cantata in 1723, his first year as "Thomaskantor" in Leipzig, for New Year's Day, which is also the Feast of the Circumcision of Christ. The prescribed readings for  the feast day were from the Epistle to the Galatians, by faith we inherit (), and from the Gospel of Luke, the circumcision and naming of Jesus eight days after his birth (). The unknown poet, possibly Picander, refers only in a general way to the readings: he mentions the naming at the end of movement 4, "" (name of Jesus), and he starts every line in the following aria with "Jesus". Otherwise the text stresses praise and thanks for the gifts of the past and prayer for further blessings. The poet compiled for the opening chorus a verse from Psalm 149 (), three  verses from Psalm 150 (), and in between the first two lines of Martin Luther's "" (German Te Deum) "" (Lord God, Thee we praise). The words from the "Te Deum" appear again in the second movement, interspersed by recitative. The closing chorale is the second stanza of Johannes Hermann's "" (1591). Bach first performed the cantata on 1 January 1724. He performed it again in the second half of the 1730s. Probably in Bach's revision process, parts of the original music got lost: for the first two movements only the vocal parts and the violin parts survived. Reconstruction of the  missing parts was attempted by Bernhard Todt (1904), Walther Reinhart (1948), Olivier Alain (1971), Diethard Hellmann (1995), Ton Koopman and Levente Gyöngyösi, Masaaki Suzuki and Masato Suzuki (2012). In his "Christmas Oratorio" of 1734, Bach dedicated the complete Part IV for New Year's Day to the naming of Jesus, told in the one verse from the Gospel of Luke, first performed on 1 January 1735. Scoring and structure. The cantata in seven movements is festively scored for alto, tenor and bass soloists, a four-part choir, three trumpets, timpani, three oboes, oboe d'amore, two violins, viola, and basso continuo  including bassoon. The instrumentation is known from the extant closing chorale, although most parts for the first movements are lost. Music. The opening chorus on three psalm verses and two lines from Luther's "Tedeum" is a complex architecture in three sections. A concerto is concluded by the liturgical melody of "" in unison, a choral fugue "" (Everything that has breath) is concluded by a similar "", the final section "Halleluja" is a shortened reprise of the first. In the second movement, the liturgical melody is set four-part and interrupted by recitatives. The following alto aria is dance-like and simple , the duet is accompanied by an obbligato instrument which may be oboe d'amore or violin. Gardiner tried both, but then chose a viola d'amore instead. Neither movement has a da capo. The strings intensify the prayer of the last recitative. The choir of trumpets marks the ending of every line in the closing chorale.
