Johann Sebastian Bach - Martin Luther - Chorale: "Gelobet seist du, Jesu Christ" (BWV 91 No. 1)

Bach's chorale setting from Cantata BWV 91 masterfully transforms Martin Luther's 1524 Christmas hymn into a rich polyphonic tapestry. Composed for Christmas Day 1724 in Leipzig, it features the soprano carrying the original melody while lower voices and instruments create intricate counterpoint. The opening movement uniquely employs four distinct choirs (voices, horns, oboes, strings), with Bach using chromatic lines for "human poverty" and angelic coloraturas for "divine abundance" in later movements.
