J. S. Bach's cantata Bleib bei uns, denn es will Abend werden, BWV 6, is first performed in Leipzig on Easter Monday.

Johann Sebastian Bach was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the cello suites and sonatas and partitas for solo violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been widely regarded as one of the greatest composers in the history of Western music.

Bleib bei uns, denn es will Abend werden, BWV 6, is a cantata by Johann Sebastian Bach for use in a Lutheran service. He composed it in Leipzig in 1725 for Easter Monday and first performed it on 2 April 1725.

Easter Monday is the second day of Eastertide and a public holiday in more than 50 predominantly Christian countries. In Western Christianity it marks the second day of the Octave of Easter; in Eastern Christianity it marks the second day of Bright Week.
