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.
This is a superb recording of the Two-Part and Sinfonias (Three-Part Inventions) of Johann Sebastian Bach. Kenneth Gilbert is a wonderful interpreter of Bach's keyboard music and in this recording plays an instrument made in 1671 by Jan Couchet that was subsequently enlarged in 1778. The Two-Part Inventions and Sinfonias consist of 15 parts; they were written as technical exercises and as composition demonstration pieces originally for his son Wilhelm Friedemann. The various pieces were probably written separately and were gathered together by Bach in major/minor key sequence and published in 1723. The recording is clear and well balanced. Kenneth Gilbert plays beautifully; the music is lively without being ostentatious.
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.
The Amsterdam Bach Soloists comprise an ensemble of ten or so musicians. They play modern instruments but base their musical approach on ''an undogmatic use of authentic interpreting practice, so that the rich potentialities of the modern instruments can be combined with the baroque way of performing, which is in keeping with the accomplishments of Nikolaus Harnoncourt with the Concertgebouw Orchestra''. Most of the players are, in fact, drawn from the Concertgebouw, though there are some from Frans Bruggen's Orchestra of the Eighteenth Century. Nowadays Bach's didactic but very beautiful The Art of Fugue, is widely regarded as a work for solo harpsichord. Bach himself left no precise indication concerning instrumentation but the music was engraved in open score which places each individual voice or strand of the texture on a separate stave. This practice was not uncommon in contrapuntal keyboard works and is one of several features pointing towards the solo harpsichord as being Bach's most likely intention. Nevertheless, since 1924, when the Swiss musician Wolfgang Graeser set the canons and fugues for various combinations of instruments, the practice of performing The Art of Fugue with a mixed ensemble has remained popular.
Even though Angela Hewitt's repertoire is quite extensive and diverse, encompassing the Baroque, Classical, Romantic, and modern eras, her true specialty is the music of J.S. Bach, which she has recorded almost exclusively for Hyperion since the 1980s. With this recording of The Art of Fugue, Hewitt completes her long-running series of piano renditions of the solo keyboard works, and while not everyone is convinced that Bach composed this study of fugal techniques for the keyboard, Hewitt's performance is credible and satisfying. She controls the often unwieldy counterpoint by regarding the lines as if they were vocal parts, and her phrases are shaped by natural breathing points, as well as the different emotional qualities she brings to each fugue and canon. The Art of Fugue can be daunting for both performer and listener because its persistent tonality of D minor and monothematic material can be quite tedious in the wrong hands.
