Musical Offering - C.P.E.B.: The Piano Quartets Music CD

"Absolutely lovely!" "Focused" "The best performance of the Hamburger Sonata I've ever heard." Album Liner Notes by Matthew Hall Copyright c 2013 Ad Parnassum, Inc. The importance of Carl Philipp Emanuel Bach's chamber music for late eighteenth-century and early nineteenth-century musical culture is enormous. Throughout his writings, C.P.E. Bach repeatedly acknowledged his debt to his father. But it is C.P.E. Bach, not J.S. Bach as is often misstated, of whom Mozart, speaking for his generation, said, "He is our father; we are all his children. Whatever we may do rightly we learned from him; and whatever he has not taught us is not worth knowing." Haydn and especially Beethoven were avid collectors of C.P.E. Bach's music. The young Mendelssohn first encountered the music of the Bach clan through his great-aunt Sara Levy, a long-time patron of Emanuel and Wilhelm Friedemann Bach as well as a collector of the music of J.S. Bach and several of the farther-flung Bach sons. It was for Sara Levy's Berlin salon that Emanuel Bach's quartets were almost certainly written. While Mendelssohn's 1829 revival of the St. Matthew Passion looms large in the story of his connection with the Bachs, it is equally worth remembering that Mendelssohn's first published works are his three piano quartets, op. 1-3, modeled on Bach's own quartets, Wq 93-95. Thus Emanuel Bach's output is at once a summing-up of High Baroque traditions, a model for Classic idioms, and even a jumping-off point for the early Romantics. Despite his central importance for the musical culture of his own time, C.P.E. Bach's music plays only a small-but happily growing-part of our modern concert life. Perhaps some of his obscurity is attributable to his idiosyncratic musical language: it is soaked through with asymmetrical melodic writing, extreme and sudden harmonic shifts, and elaborately embroidered textural and contrapuntal writing, which together produce the drastic expressivity which perplexes as many listeners as it delights. Charles Rosen has described this idiom as "arbitrary" and even "incoherent"; consider, for example, the sudden stoppages and changes of affect in the first movement of Wq 77. To be sure, Bach's language is a far cry from the exquisite simplicity and restraint of that of the Viennese classicists; but surely Rosen's indictment amounts to little more than the observation that C.P.E. Bach is not a Viennese classicist. One could just as easily say that Mozart's music, considered from a Rococo perspective, is "four-square and boring," which of course it is not: within the given constraints of the musical idiom, as much imposed by the surrounding musical culture as it is chosen by the composer, Mozart explores infinite and sublime variety and expression. This is all the more true of C.P.E. Bach: for if Mozart probed the widest possible breadth within his musical idiom, Bach sought actually to coalesce a new musical language at a time of swift development in musical taste, all while producing pieces of music within this ever-evolving style. In this way Bach's trailblazing outlook-his desire to capture novelty and expressivity, form and fantasy, learnedness and songfulness, pairs which are always in tension-make him rather more like the modernist composers of the twentieth century than like his contemporaries. C.P.E. Bach's Berlin style in particular, exemplified by the quartets, attains a precarious balance between the light, tuneful character of purely galante music, as is heard in Wq 133, and the traditional (and by 1740 or so, archaic) contrapuntal practice exemplified by J.S. Bach's style. The Berlin style distinguishes itself from the musical styles of Hamburg and Dresden, cities which had Italian opera houses since the late seventeenth century-whereas Berlin's Hofoper was inaugurated only in 1742-and whose instrumental styles were suffused with Italian operatic influences. (Here again, Wq 133 is a prime example.) The Berlin style is therefore perhaps the only purely instrumental eighteenth-century style. By imbuing the traditional contrapuntal practice with galante melodiousness, the style is at once progressive and conservative, but neither reactionary nor archaic. This is the musical language that made possible the notion of "absolute music" which dominated the aesthetic outlook of the nineteenth century, and which to a great extent still characterizes our modern concert life. The affinity between our modern musical values and those embodied by C.P.E. Bach's music perhaps best explains the composer's relative obscurity for much of the nineteenth and twentieth centuries and the resurgence of interest in his music of the past fifty years or so. If Emanuel Bach's music was temporarily forgotten in the nineteenth century, his role as an early promoter of the piano was not. Indeed, Bach's most lasting legacy was his treatise on keyboard playing, Versuch über die wahre Art das Clavier zu spielen (1753), the text that revolutionized Baroque keyboard technique and provided the basis for modern pianism. Baroque keyboard fingering is purposefully unequal: the technique cultivates the third (longest) finger as the strongest for use in strong metrical positions. The second and fourth fingers are commonly used but in weaker metrical positions, while the little finger and especially the thumb are not used preferentially, but rather only in the necessary cases of stretches or many-note patterns. This is in sharp contrast to the principle of nineteenth-century fingering that each of the five fingers of the hand should be equally strong. Central to this manner of even fingering is the use of the "thumb-under" technique, in which the thumb is crossed under the other fingers to facilitate a smooth and inaudible change in hand position. The thumb-under technique was first laid out systematically by Clementi in his Introduction to the Art of Playing the PIanoforte (1801), through which it became the basis of Czerny's pedagogy and the bane of young pianists everywhere. But Clementi did not invent the technique: if we believe the Versuch, J.S. Bach did. In his discussion of the use of the thumb, C.P.E. Bach reminisces: My father of blessed memory told me that in his youth he heard old masters who never used the thumb except in large stretches in which it was absolutely necessary. But he lived in an age which witnessed great changes in the development of musical style, and so was obliged to reconsider the practice of fingering, in particular the use of the thumb. And, not able to resist a double pun, he concludes: And so now the thumb may be at a stroke elevated from complete inactivity to the place of the pivotal finger. The persistent use of the thumb is the first necessary step towards the development of the even, modern style of fingering. The musical ramifications of this are obvious: it facilitates the long phrasing of melodies so evident in Bach's slow movements (especially the slow movement of Wq 77), the fantasia-like arpeggiando textures of the keyboard which the composer favors in developmental passages as in the first movements of Wq 93 and 95, and fast, lengthy scales such as those in the first movement of Wq 94 and last movements of Wq 93 and 95. More importantly, however, Bach's pioneering use of the piano does more than simply enable new kinds of idiomatic keyboard writing; the impact of the piano's presence is felt by all the members of the ensemble. In the Versuch, Bach had reaffirmed the traditional continuo team of harpsichord and 'cello; yet the original prints of the score and parts of the quartets, dating from Bach's last year 1788, lack a separate line or part for a 'cello. Of course, that falls short of demonstrating that the inclusion of the 'cello was not envisioned; in fact, there is ample iconographic and documentary evidence for the practice of part-sharing between keyboard and bowed bass players. What it does show, subtly but incontrovertibly, is that the use of th
