A. Weimar Period.
1. Four Fantasias, in D, A minor, G minor, and B minor (211, p. 28; 215, pp. 3, 30; 216, p. 9):[26]
2. Four Toccatas, in E minor, D minor, Gr minor and major (210, pp. 3, 30; 211, p. 4; 215, p. 17):
3. Six Fugues, two in A, and two in A minor (212, p. 10; 216, p. 20; 212, p. 14; the fourth in MS. at Berlin), together with two, in A and B minor, on subjects taken from Albinoni (216, p. 25; 214, p. 12):
4. One Prelude and Fugue in A minor (211, p. 14): to these we may perhaps add the well-known one in B flat of which the subject is on the (German) notes contained in the name Bach (B flat, A, C, B natural) but of which the genuineness is suspicious (212, p. 24).
B. Coethen Period.
1. A Fantasia in C minor (212, p. 2).
2. Four Fantasias and Fugues, in D minor (the famous Chromatic Fantasia), B flat, and D (207, p. 20; 212, pp. 28, 32).
3. Two Toccatas, in F sharp minor and C minor (210, pp. 10, 20.)
