It is significant that in the whole of the “48” Bach included just one (E minor in the first book). The problems are those of creating enough harmonic substance (there are fewer voices than there are notes in the triad) and – more acutely – of maintaining continuity satisfactorily. Every time that one inserts a breathing space for one of the voices, the texture reduces to a single, unsupported line, and this can be dangerous. Another problem is that of creating length. Perforce, if the voices are only two, an exposition with one entry per part is over quickly. So one has to be enterprising about the number of keys visited and generous with codettas and episodes in order to write a reasonably long movement. Bach’s four Duetti in the third part of his Clavier-Übung are inimitable monuments to this kind of spinning-out. Why this fugue is “exemplary” (to which I add the subtitle of Solfeggio – a contrapuntal exercise, usually for the purpose of vocal training) is that it is a little severe and didactic in tone, as if conceived as a demonstration piece for the schoolroom. It will remind players of Bach’s Inventions in two parts, particularly in its relentless pursuit of equality between the two voices, in which every scrap of significant thematic material in one voice (not only the subject and countersubject but also episodic motives) makes its way at some point into the other. It is unnecessary to write an extended analytical commentary on this brief movement. The modulating subject has a tonal answer. The “middle entries” are appropriately in related major keys. The subdominant appears in the final exposition. Little snatches of canonic imitation occur. There are a few very short divagations to add interest and novelty. This is not a very clever or complex fugue, but what pleases me most about it most is that it keeps up its momentum to the end, aided by a liberal use of syncopation. In a two-part fugue, to sustain momentum has to be the prime goal to which all other considerations are secondary. I have always found syncopation a marvellous way of breathing life into even slowly moving music. Let me take this opportunity, since the author himself – the creator and manager of this site – would be embarrassed to do this on his own behalf, to cite Andrea Bornstein’s three-volume study of the early (up to 1744) two-part “didactic duo”, entitled Two-Part Italian Didactic Music (Bologna, Ut Orpheus Edizioni, 2004). Here one can find the historical and musical background to this austere kind of fugue, which stretches back far beyond the beginnings of fugue proper in the seventeenth century. Let this little fugue also be a tribute to him and to that study. The pdf and midi files of this piece may be downloaded HERE
