Note 91 — THE PRELUDES AND FUGUES OF J.S. BACH TOCCATAS—FANTASIAS—THE PASSACAGLIA—THE SONATAS

Let it be remembered that Bach, imitating these same Sonatas in composing the Lamento of the "Capriccio upon the departure of his most beloved brother" (1704), employs this motif as a basso quasi ostinato, and that in the Easter Cantata written in the same year the viola sorrowfully gives expression to the same theme.
