Sharp practice

04 Prelude C#

This Prelude and Fugue has, as you can see, a considerable number of sharps; in fact it has seven, moving every note of the scale up a semitone.  In ‘just’ tuning the results of performing in such an exotic key (or, even worse, F#!) would have been, to say the least, rather unpleasant. But for Bach – set on demonstrating that his well-tempered keyboard could be effective in no matter how many sharps or flats – the far reaches of the tonal system held no such terrors.
