Suite No. 4 in D major, BWV 1069

• Ouverture
• Bourrée I/II
• Gavotte
• Menuet I/II
• Réjouissance

Instrumentation: Trumpet I/II/III, timpani, oboe I/II/III, bassoon, violin I/II, viola, basso continuo

The opening movement of this suite was reused by Bach as the choral opening to his cantata Unser Mund sei voll Lachens, BWV 110. The voices come in at the opening of the fugal gigue, so that their singing of Lachen (laughter) sounds like "ha ha ha", a technique Bach used a few times in his vocal works.
