28 Eldest son of Heinrich Bach (see Table VI.). Whether he was Court as well as Town Organist at Eisenach cannot be stated positively. 29 The _Alt-Bachische Archive_ is a collection of the compositions of various members of the family, before and after Johann Sebastian, formed largely by the latter. From C. P. E. Bach it passed to G. Pölchau and from him to the Berlin Royal Library. 30 Johann Christoph composed several Motets (see them discussed in Spitta, i. 75 ff.). The daring work to which Forkel alludes was written about 1680 and is lost. Though the augmented sixth was then and remained unusual, Johann Christoph’s is not the earliest use of it. Spitta finds it in Giacomo Carissimi (1604-74). 31 The Cantata (“And there was war in heaven”) is analysed by Spitta (i. 44). The score is unusually full: two five-part choirs; Vn. 1 and 2, 4 Violas, Contrabasso, Fagotto, 4 Trombe, Timpani, Organ. In 1726 Johann Sebastian Bach wrote a Cantata for Michaelmas on the same text (Rev. xii. 7). 32 Spitta (i. 101 n.) characterises the statement as “a mythical exaggeration.” In a chapter devoted to the instrumental works of Johann Christoph and his brother he instances a collection of forty-four Organ Chorals by the former, not one of which is in five parts. 33 In the Bach genealogy already referred to C. P. E. Bach designates Johann Christoph a “great and impressive composer.” 34 A _Lamento_ published under Johann Christoph’s name seems actually to have been composed by his father Heinrich (see Pirro, _J.-S. Bach,_ 9 n.). Johann Christoph, however, is the composer of the Motet _Ich lasse dich nicht,_ so often attributed to Johann Sebastian. 35 See Table VI. He was the father of Johann Sebastian’s first wife. 36 See note, p. 4 supra. 37 Spitta (i. 59 ff.) mentions twelve Motets by Michael Bach. Several of them are for eight voices. Forkel probably refers to the most remarkable of Michael’s Motets, in which he detects the romantic spirit of Johann Sebastian. It is set to the words _Unser Leben ist ein Schatten,_ (_Life on earth is but a shadow_). The first choir consists of 2 S., A., 2 T., B., and the second choir of A. T. B. only. Spitta analyses the work closely (i. 70-72). Novello publishes his five- part Motet _Christ is risen_ with an English text. 38 He succeeded his cousin Johann Christoph at Eisenach in 1703. 39 Spitta (i. 24 ff.) mentions four Suites, or Overtures, Clavier pieces, and Organ Chorals as being by him. That Johann Sebastian Bach highly esteemed the Suites is proved by the fact that he copied the parts of three of them with his own hand at Leipzig.
