289 They are all printed in Novello bk. 19, and are three in number, on the melodies “Christ, der du bist der helle Tag”, “O Gott, du frommer Gott,” and “Sei gegrüsset, Jesu gütig.” The pedal is only required in one movement of the first, in none of the second, and considerably in the third. Without question all three date from Bach’s earliest period, but whether they were written at Arnstadt or Lüneburg cannot be stated. 290 The fullest collection of these miscellaneous Organ Choral Preludes is in B.G. XL. Not counting variant readings they number fifty-two, besides two fragments and thirteen of doubtful authenticity, of which two are sets of Variations. The Novello edition contains fifty-two in bks. 18 and 19. To these must be added the “Eighteen” Preludes on Choral Melodies, which Forkel nowhere mentions, as well as the third Part of the _Clavierübung,_ the _Schübler Chorals,_ and the Variations on _Vom Himmel hoch,_ to which he has already made reference in the first section of this chapter. As he does not mention it specifically, it is to be inferred that Forkel was ignorant of the existence of the _Orgelbüchlein_; otherwise he could hardly have failed to introduce it in this section. All Bach’s Choral Preludes, miscellaneous and in collections made by himself, are in Novello’s edition, bks. 15-19. A useful key to their melodies is provided by bk. 20. For more detailed information see Terry, _Bach’s Chorals,_ Part III. 291 The large number of MSS. of many of the miscellaneous Preludes is made evident in the introduction to B.G. XL. 292 The Sonatas in E flat major, C minor, and D minor are in N. bk. 4; E minor, C major, G major in N. bk. 5. 293 The so-called “Sonatas” were actually written for a Clavicembalo with two manuals and a pedal. Bach’s Autograph of them belonged to his second son and an earlier copy of them to Wilhelm Friedemann. Both are now in the Berlin Royal Library. Friedemann went to Dresden as Organist in 1733 and Spitta is of opinion that the whole of the six Sonatas were in existence by or soon after 1727. If so, they must be regarded as the outcome of Bach’s early years at Leipzig. See Spitta, iii. 212 ff. and Schweitzer, i. 278. 294 None are extant. Spitta, iii. 213 n., conjectures that Forkel refers to the Trios in D minor and C minor (N. bks. 2 p. 54, 12 p. 108) and the Pastorale in F major (N. bk. 12 p. 102.) His incomplete knowledge of the Organ works is revealed by Appendix V. infra. 295 This is a pure conjecture and Schweitzer scouts it (i. 416 n.).
