"This fugue is a unique piece. I think there is a certain humour in it."

Fugue and fugue in A

In this surprising duo, Bach – who is often so strict – shows a different side of himself.

Prelude and fugue are a practically inseparable couple, especially in Bach’s case. But here, deep in the first book of the Wohltemperirte Clavier, a different duo crops up. This prelude is actually a fugue as well, and a three-part one to boot. The ‘real’ fugue sticks to the rules, but remains a true puzzle nonetheless. The clear fugue-as-prelude, on the other hand, cheats a bit by introducing the theme and counter-theme at the same time. Through this combination, Bach emphasises the ambiguous character of the key of A major. The counter-theme in the bass with its descending chromatic line may be interpreted as sombre, while the theme in the right hand has a more cheerful feel to it, with elegant ornamentation (which soon becomes an independent motif) and a tense pause, followed by the release of a long string of notes. The helter-skelter of the runs gradually takes over the prelude, making a detour to minor and back again, to end as it began.

 But then comes a note like an exclamation, and silence! To confuse us even further, Bach follows the fugue theme with a series of unmelodious leaps, so that our ears can hardly distinguish the key. As we said, everything about this atypical fugue is correct – it is even an extremely pure one as regards musical material – but the curious theme, no more than leap and rhythm, continually puts the listener on the wrong track. Within a single bar of nine beats, Bach writes the musical equivalent of an optical illusion. Just as you have become accustomed to a regular movement in four, a strong exclamation of the theme abruptly calls you to attention. The fugue also goes over the lines, for example when the themes interrupt one another early on (this tension-raising stretto technique usually comes only at the end of a fugue). It also does so at the beginning, when Bach coolly suggests a fourth part through introducing an extra theme.

Das Wohltemperirte Clavier, BWV 846-893
Composing 48 keyboard pieces in all 24 keys was the sort of challenge Bach enjoyed. In each of the two parts of the Wohltemperirte Clavier, he brought together the musical couple prelude and fugue 24 times; twelve in minor keys and twelve in major. In the preludes, he gave free rein to his imagination and demonstrated mathematical tours de force in the fugues. In contrast to the iron discipline Bach had to apply to his church compositions, here he could abandon himself to intellectual Spielerei without worrying about deadlines.

The first part of the Wohltemperirte Clavier dates from 1722, although it contains some music that was written in the preceding five years. There is less clarity about the history of part two. Bach compiled this second manuscript only around 1740, although once again some of the preludes and fugues it contains date from a much earlier period. Bach described the target group for this collection of pieces as follows: "Zum Nutzen und Gebrauch der Lehr-begierigen Musicalischen Jugend, als auch dere in diesem studio schon habil seyenden besonderem ZeitVertreib" (For both the education of the industrious musical youngster and the enjoyment of those well-versed in this material).
