In his recording of Bach's 48 Colin Tilney, unlike his fellow competitors in the same repertory, plays both a clavichord (Book 1) and a harpsichord (Book 2). Why not? Bach's title for the first book of 24 preludes and fugues, The Well-tempered Clavier leaves both this issue and that of tuning wide open. The clavichord was a favourite instrument of Bach's, so was the harpsichord and the organ; indeed, I am sorry that Tilney does not include a chamber organ since some of the pieces, the E major Prelude and Fugue (Book 2), for instance, seem well-suited to it. Tilney's performance of the 48 differs again from almost if not all others in the sequence which he adopts in playing the preludes and fugues. But an apparently random approach is in fact nothing of the kind, but one that is directly linked with tuning. We know that Bach himself was a master in matters of tuning as he was in all other aspects of his craft. What we do not know is the exact nature of his tuning.
Essential: a masterpiece of folk music
Planxty begins its remarkable sophomore release The Well Below the Valley with the pipe-led "Cunla," an engaging round sung by founder Christy Moore. Impeccably played dance tunes, soulful laments, and rollicking narratives follow, allowing listeners access to the full breadth of the group's many talents.
Although not quite at the level of profundity of his teacher Gustav Leonhardt's recording, Kenneth Gilbert's 1983 recording of Book 1 of Bach's The Well-Tempered Clavier does have a style and polish that Leonhardt's too often lacked. Thus, while Leonhardt goes further into some of the minor-key fugues to find intellectual and spiritual depths that Gilbert does not plumb, Gilbert's playing is so much more elegant and graceful than Leonhardt's that it is difficult to choose between them. For listeners who approach The Well-Tempered Clavier as a volume of virtuoso works whose success depends on the effortless refinement of the player, the Gilbert, with its superbly remastered sound, will be the one to get. For listeners who approach The Well-Tempered Clavier as a volume of prayers written as preludes and fugues, the Leonhardt will be preferable. Both are superb and both belong in any Bach collection.
