266 The true explanation seems to be that the Prelude of the first Suite (A major) is based upon a Gigue by Charles Dieupart (d. circ. 1740), a popular teacher and composer in England. The words fait pour les Anglois, which head the A major Suite in an early MS., have been wrongly interpreted as applying to the whole set of six. They merely indicate Dieupart’s borrowed Gigue. See Grove, vol. i. 701, and Parry, _J. S. Bach,_ p. 463. A copy of the work exists, of date 1724-27, made by one of Bach’s pupils. But the composition of the Suites may certainly be assigned to the Cöthen period. They are published in P. bks. 203, 204. 267 The French Suites undoubtedly date back to the Cöthen period, since they figure, though incomplete, in the _Notenbuch_ of A. M. Bach (1722). They are published in P. bk. 202. 268 Forkel’s incomplete catalogue may be compared with the Bachgesellschaft volumes III., XIV., XXV. (1), XXXI. (2), XXXVI., XLIL, XLIII. (1 and 2), XLV. (1). See generally Schweitzer, ch. 15, and Pirro, pp. 218 ff. 269 P. bks. 205, 206, 208, 212 (fragment in F minor), 214, 215, 1959. 270 P. bks. 200, 210, 211, 212, 214, 215, 1959. 271 For the most part these youthful works will be found in B.G. XXXVI. 272 P. bk. 207 p. 16. 273 In C minor (P. bk. 200 p. 10). 274 In P. bks. 232, 233. 275 Suite in A major (P. bk. 236), Sonata in E minor (P. bk. 236), Fugue in G minor (P. bk. 236), four Inventions (P. bk. 2957), Sonata in G minor (BG. ix. 274; not in P.), Sonata in C major for 2 Violins and Clavier (P. bk. 237). 276 There are six Sonatas for Flute and Clavier, in B minor, E flat major, A minor, C major, E minor, E major (P. bks. 234, 235). 277 There are three Sonatas for Clavier and Gamba, in G major, D major, G minor (P. bk. 239). 278 Forkel omits two Sonatas for Violin, Flute, and Clavier, in G major and C minor (both in P. bk. 237). 279 As Forkol mentions in secs. 4, 5, 6 the Concertos for two, three, and four Claviers, perhaps he had in mind here seven Concertos for Clavier and Orchestra (P. bks. 248-254). A Concerto for Clavier, Violin, Flute, and Orchestra (P. bk. 255 p. 4) in A minor also should be mentioned. Also an Overture, in G minor, for Clavier and Strings (B.G. XLV. (1) p. 190; not in P.) 280 P. bk. 257 p. 4. 281 P. bk. 256 p. 4.
