Harpsichordist Martha Cook here records Bach's Kunst der Fuge, BWV 1080 (The Art of the Fugue), with a specific interpretive framework in mind. The work, Cook believes, was devotional and intimate in intent; it is, she writes, a "musical prayer," and it embodies the parables and exhortation found in the biblical Book of Luke, 14:27-35. Interested readers are invited to consult the booklet for more details. Making the supposition work involves discarding the version of the work published after Bach's death by C.P.E. Bach and others, and it also involves some of the numerology that so often seems to crop up in connection with Bach's larger works. There's some justification in earlier German music for regarding Bach's instrumental music in this programmatic way; Bach would have known the Biblische Historien keyboard sonatas of 1700 by one of his key predecessors, Johann Kuhnau. But what's missing is any evidence of why Bach, by the end of his life a revered figure, might have wanted to embed secret messages in Die Kunst der Fuge. The unalloyed good news is that you can disregard the stated method of interpretation and listen to the performance in the abstract. It's very powerful.
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.
