Canon, 'Da ist das Werk', WoO 197 (mp3)
12 ducats would be roughly $1,600 in present day money.
The canon is for five voices, with entries after two bars at the unison. We notice that the first triplet of bar 6 is identical to the one in bar 8. This means that at this point there will always be two voices in unison. Bad counterpoint ! It shows the haste with which Beethoven must have jotted down this canon, because only the shortest of reflections is necessary to see how this can be corrected : the first beat of bar 8 should just be : C - G - E. [There is a second good reason for this correction, can you spot it? ] But of course it is the counting of the ducats that counts ! Who cares about textbook rules at such a moment of high excitement ?
Ludwig Misch, in his chapter on the canons, raises the question whether the B natural in bar 2 shouldn't be a B-flat. It is not clear whether he actually sees something resembling a flat there in the autograph, or whether he wants to see it, for theoretical reasons : this B natural clashes with the C of bar 6, and by lowering the B to B-flat the dissonant will lose much of its sharpness. However, as the current recording shows, the B natural against C does not create any problems, so Misch should not have worried.
