Zweig MS 45

Both incomplete. Autograph score. Written in ink on systems of four staves. A single leaf, originally part of a bifolium, with the page nos. ‘1’ at top left of the recto and ‘4’ at top right of the verso, apparently not in the composer’s hand. Contents:

Recto. The first 18½ bars of ‘Treuer Gott’. Tempo direction ‘Largo’. Headed ‘Choral. Treuer Gott ich muss dir klagen. a Hautbois d’Amour. 2 Clavier et Pedale. di J. L. Krebs’ in the upper margin. The oboe d’amore is notated in C. The first two systems cancelled with a single stroke in brown crayon.

Verso. The concluding 36 bars of ‘Wie schön leuchtet der Morgenstern’, with at the end ‘S.D. Gloria. d[ie] 4 octob. 1746.’. The second instrument, which like the oboe d’amore in ‘Treuer Gott’ simply plays the chorale melody, is notated in A. Systems 2-4 and 5 cancelled with single strokes in ink.

Number in H. Hinterberger, Vienna, cat. IX added in pencil at foot of recto.

The separation of the two halves of the original bifolium has resulted in Zweig MS 45 containing the beginning of one work and, on the verso, the conclusion of another. The two leaves of the bifolium may have become separated by wear and tear. In any case, they were offered as two separate items in Hinterberger cat. IX. Zweig MS 45 does not appear in Hinterberger cats. 18 and XX of 1937, but the second leaf of the bifolium is also listed in cat. 18, and was one of a number of items from that catalogue purchased by Martin Bodmer. The description of the other leaf of the original bifolium in Seebass gives the heading ‘Wie schön leuchtet der Morgenstern. a Hautbois d’Amour & [recte 2?] Clavier et Pedale di J.L. Krebs’, which is followed by the note ‘in Dis transp: con Oboe ord: Fr. [sharp].’ in another hand (see McLean, Krebs Collected Works, p. xix for note on key notation for oboe d’amore and oboe); the verso, the continuation of ‘Treuer Gott ich muss dir klagen’ (identified by Seebass , Musikhandschriften der Bodmeriana, by the alternative text for the chorale melody, ‘Freue dich sehr, o meine Seele’) from Zweig MS 45, has at the end ‘S.D. Gloria’. The publication of ‘Treuer Gott’ by Herzog has the tempo direction ‘Largo’ as in the present manuscript. McLean (p. xxi) includes ‘Wie schön leuchtet der Morgenstern’ in his appendix of missing works; it apparently remains unpublished.
