Charles Burney visited C.P.E. Bach in Hamburg in October 1772,
            publishing his account of the encounter in The Present State of
            Music in Germany, the Netherlands, and United Provinces
            in the following year. He observed that "Hamburg is not, at
            present, possessed of any musical professor of great eminence,
            except M. Carl Philip Emanuel Bach; but he is a legion!" For
            Burney, although he admired Bach's "vocal and miscellaneous
            compositions", Bach's genius was most evident in "his productions
            for his own instruments, the clavichord, and piano forte, in
            which he stands unrivalled". Visiting Bach at his home, Burney was
            overjoyed when Bach "was so obliging as to sit down to his
            Silbermann clavichord, and favourite instrument, upon which
            he played three or four of his choicest and most difficult
            compositions, with the delicacy, precision, and spirit, for which
            he is so justly celebrated among his countrymen. In the pathetic
            and slow movements, whenever he had a long note to express, he
            absolutely contrived to produce, from his instrument, a cry of
            sorrow and complaint, such as can only be effected upon the
            clavichord, and perhaps by himself". The experience confirmed
            Burney - no bad judge - that Bach was "one of the greatest
            composers that ever existed, for keyed instruments".
         
         
            He doesn't hold quite such a position in modern times. No doubt
            some of C.P.E. Bach's contemporary fame owed something to his own
            skills, as the passage from Burney implies. But his works for
            keyboard are, in themselves, fascinating and often remarkable. He
            was the author of the Essay on the True Art of Playing
            Keyboard Instruments (1753-62), one of the most
            important musical treatises of the eighteenth century. He had, in
            short, thought long and hard about the writing and playing of
            keyboard instruments, drawing on his own very extensive experience,
            the instruction he had received from his father and his observation
            and study of the playing and compositions of others. His own
            keyboard sonatas can, in one light, be viewed as a kind of bridge
            between his father, J. S. Bach and Haydn. Certainly there are
            places - particularly in the early works - where the influence of
            his father is readily apparent and there are others where, as he
            developed the empfindsamer Stil (the "highly-sensitive
            style"), one hears anticipations of the keyboard writing of Haydn
            (and beyond). The danger in viewing his work in this light is,
            however, that we don't pay sufficient attention to the music
            itself, rather than to where it has come from or is going to,
            stylistically speaking.
         
         
            One problem for the modern performer/listener is that Bach was
            himself devoted to the clavichord, which was very much his
            preferred instrument in the keyboard family. The intimacy of the
            instrument, its capacity for the production of distinctively
            'personal' sounds, perhaps encouraged the experimental and
            subjective sides of Bach's personality. Much of his writing for the
            keyboard eschews strict adherence to the principles of classical
            regularity; simple repetitions are often avoided, there is a
            fascination with surprising and strongly characterised sonorities.
            How adequately the modern piano can do justice to these must be a
            doubtful matter. Miklós Spányi has recorded, for BIS,
            a long series of works for the solo keyboard, played on a
            clavichord; he plays the music with great love and understanding,
            with a quasi-improvisatory intimacy and a rich palette of tone
            colours. This would, I think, be my preferred way of hearing this
            music. But we needn't exclude other alternatives - any more than we
            do with the music of Bach's father. Certainly many hearers seem to
            have enjoyed Mikhail Pletnev's flamboyant 1998 recording of
            Sonatas and Rondos by Bach (on DG), which exploits something
            like the full resources of the modern grand. Pletnev certainly
            stresses the 'romantic' anticipations in C.P.E.'s writing; I
            remember one reviewer remarking that, at times, one seemed to be
            listening to Liszt rather than C.P.E. Bach. There is also a fine CD
            by Carole Cerasi on metronome, on which six sonatas are played on
            the harpsichord.
         
         
            On this new issue from Naxos, the young Austrian pianist
            Christopher Hinterhuber we have performances which might be
            'located', as it were, somewhere between Spányi and Pletnev.
            The music is played on a modern piano, but with a sense of scale
            and sonority which is stylistically very sympathetic, and without
            the sometimes excessive flamboyance of Pletnev. I was very
            favourably impressed by Hinterhuber's playing on a recent Naxos
            disc of piano concertos by Ferdinand Ries, and that favourable
            impression is confirmed here. He plays this complex music, full of
            unexpected twists and turns, abrupt transitions of mood and
            direction, with attractive lucidity of thought and clarity of
            technique.
         
         
            If you re a devotee of C.P.E. Bach's solo keyboard music,
            Spányi's series is the place to go. If you prefer the sound
            of the modern piano, and want a sampler of this music,
            Hinterhuber's recording will serve your purposes well.
