Title: Unser Mund sei voll Lachens, BWV 110
Content:  Unser Mund sei voll Lachens (May our mouth be full of laughter), BWV110, is a church cantata by Johann Sebastian Bach. He composed the Christmas cantata in Leipzig for Christmas Day and first performed it on 25 December 1725. Bach composed the cantata in his third year as Thomaskantor in Leipzig. He used a text by Georg Christian Lehms, which was published already in 1711. The text has no recitatives alternating with arias, but instead three biblical quotations, opening with verses from Psalm 126, then a verse from the Book of Jeremiah about God's greatness, and finally the angels' song from the Nativity according to the Gospel of Luke. The closing chorale is taken from Caspar Füger's "Wir Christenleut". Bach scored the work festively for four vocal soloists, a four-part choir and a Baroque

Content:  The opening chorus is "Unser Mund sei voll Lachens" (May our mouth be full of laughter). It calls for all instruments to perform. The text "concludes with acknowledgement that the Lord has achieved great things for his people". Bach based the music on the overture to his fourth Orchestral Suite in D major, adding festive trumpets and timpani as well as flutes to the original music and embedding the voices. He followed the format of the French overture by instrumental slow sections framing the fast choral section. The French overture, normally played upon the arrival of the king to a performance, seemed suitable

Title: Unser Mund sei voll Lachens, BWV 110
Content:  Bach structured the cantata in seven movements. An opening chorus and a closing chorale frame a sequence of arias, a recitative and a duet. Bach scored the work for four vocal soloists (soprano (S), alto (A), tenor (T), bass (B)), a four-part choir and a Baroque instrumental ensemble of three trumpets and timpani (Ti), two transverse flutes (Ft), three oboes (Ob) (also oboe d'amore and oboe da caccia), two violins (Vl), viola (Va), and basso continuo including bassoon. The heading of the original parts reads: "J.J. Feria 1 Nativitatis Xsti. Concerto. a 3 Trombe, Tamburi. 3 Hautb. / Baßon. 2 Violini e Viola, 4 Voci è Continuo.", which means "Jesus help. First feast day of the birth of Christ. Concerto for 3 trumpets, timpani, 3 oboes, bassoon, 2 violins and viola, 4 voices and continuo". The duration is given as 27 minutes. In the following table of the movements, the scoring follows the Neue Bach-Ausgabe. The keys and time signatures are taken from the book on all cantatas by the Bach scholar Alfred Dürr, using the symbols for common time (4/4) and alla breve (2/2). The continuo, playing throughout, is not shown.

Content:  A bass recitative, "Dir, Herr, ist niemand gleich" (There is no one like You, Lord), is accompanied by the strings, which accompany the expressive line of the bass voice by "upward-pointing gestures".

Content:  the angels. In this early text, three biblical quotations alternate with arias. The closing chorale is the fifth stanza of Caspar Füger's hymn "Wir Christenleut". Bach led the Thomanerchor in the first performance in the morning of Christmas Day in the Nikolaikirche, repeated in the afternoon in the Thomaskirche. He led at least one more performance between 1728 and 1731. Some Bach scholars believed that the cantata was written in 1734 for the end of the War of the Polish Succession, but the discovery of the printed text showed that it was not related. The cantata was not published until 1876 when it appeared in the Bach Gesellschaft Ausgabe, the first complete edition of the composer's works.

Content:  In 1725, Bach typically composed alternating recitatives and arias in his cantatas, both on contemporary poetry. The text for this work is in an older style, with biblical texts interspersed with arias. Bach followed it, using different musical forms for the biblical quotations. The opening chorus on psalm verses is an adaptation of his overture to his fourth Orchestral Suite in D major, BWV 1069. The duet "Ehre sei Gott in der Höhe" is based on the Christmas interpolation Virga Jesse floruit from Bach's Magnificat in E-flat major, BWV 243a, of 1723, performed for his first Christmas in Leipzig.

Content:  A tenor aria, "Ihr Gedanken und ihr Sinnen" (You thoughts and musings), is accompanied by two transverse flutes. Dürr interprets the choice of the flutes as a symbol for the "lowly birth".
Title: Unser Mund sei voll Lachens, BWV 110
Content:  The bass aria "Wacht auf, ihr Adern und ihr Glieder" (Awaken, veins and limbs), is a final call to wake up and join the praise of the angels. Trumpet and oboe add to energetic music. The oboes double the strings or rest, for more dynamic effect. Virtuoso passages in the trumpets are reminiscent of the first movement. The first triad call of the trumpet is of martial character, and imitated by the voice. When the text refers to the strings, the winds have a rest.
