The Sinfonia n 9 in F minor BWV 795 is undoubtedly one of J.S. Bach masterpieces and it's by far the best known of the 3-part symphonies. The heart of the piece is a relentless, weary melancholy created by a descending chromatic bass line in counterpoint with a sigh motif.
Motivic, based on two tiny motifs:
1. The “lament bass,” a descending chromatic figure, familiar from
Baroque opera and cantata and associated with grieving. Bach uses
this motif in his cantata, “Weinen, Klagen, Sorgen, Sagen”and the “Crucifixus” of his Mass in B
minor.
2. The “sigh” motif: ascending third and descending step.
