prolix F minor fugue, the expressive weight of this movement is commensurate with<br />

its length.<br />

The subject has a certain kinship with many of the VIII Fugen in that it is<br />

rhythmically diverse, with prominent rests and appoggiaturas of varying lengths.<br />

Unlike these fugues however, which tend to make their effect through empfindsamer<br />

expressivity and melodic charm, this piece succeeds by means of its thorough<br />

command of the subtleties of fugal technique. Technically it is very sound, following<br />

his father’s mature practice of maintaining the integrity of each voice, not having<br />

voices enter with non-thematic material etc., and there are even a few ‘scholastic’<br />

fugal devices—notably the strict and very successful stretti in bb.48-54 and 90-96.<br />

More important, however, is the skill with which Friedemann handles his texture.<br />

Here he shows an ability to generate continuous counterpoint and sustain its interest<br />

over long periods, something we might not have been able to infer from the VIII<br />

Fugen alone. This continuity is not absolutely unrelieved. One factor that gives this<br />

fugue so much of its life and interest is the subtle flux in intensity from moment to<br />

moment. For example, although movement in semiquavers pervades the texture,<br />

occasional relaxations (bb.19, 28, 51, 66, and 100) create a sense of ease and<br />

confidence out of all proportion to their brevity. The fugue is in 3/4 time, and<br />

Friedemann exploits the possibilities for hemiola fully (bb.14-15, 34-35), sometimes<br />

extending the hemiola over several bars (bb.44-46, 65-69, 75-77), and at one point<br />

displacing the metre by one beat (bb.36-38). These passages of metrical instability are<br />

balanced by arrivals at passages of greater stability, articulating the form in a uniquely<br />

subtle, flexible way.<br />

If, for some reason, this piece had been transmitted without the Christian names<br />

of its composer (not at all an uncommon situation), there would be no incongruity in<br />

placing it alongside the other independent preludes and fugues for clavier of J. S.<br />
