Note 110 — THE PRELUDES AND FUGUES OF J.S. BACH TOCCATAS—FANTASIAS—THE PASSACAGLIA—THE SONATAS

The first part of the sonata in D minor undoubtedly dates from the year 1722; the adagio and vivace of the sonata in E minor are transcribed from the cantata Die Himmel erzählen (1723), B.-G. xviii. The last movement of this sonata was originally intended to serve as an interlude between the prelude and the fugue in G major (P. ii, 2. B.-G. xv, p. 169. The theme of the fugue is, in major, that of the first chorus in the cantata Ich hatte viel Bekümmerniss, performed in 1714), composed, according to the water-mark of the autograph, in 1724 or 1725.
