Much of the interest in works of C.P.E.Bach, the fifth child and second surviving son of Johann Sebastian Bach and Maria Barbara Bach, revolves around a certain number of compositions for solo keyboard and his orchestral works. His vocal works and a large part of his chamber music have received surprisingly little attention. Carl Philipp Emanuel Bach (1714–1788), a renowned keyboard player himself, was an extremely prolific composer, enjoying a prestigious reputation during his lifetime, with the result that his music became known far and wide. Unlike his father Johann Sebastian, who primarily concentrated on sacred vocal settings for the church, Emanuel, unburdened by cantorial responsibility, composed mostly chamber music for the court. He was particularly attracted to the trio sonata form, to which he devoted some of his finest writing. Highly experimental, composed at a time of change, these works span from the Baroque trio sonata model to the accompanied keyboard sonata, to the Classical keyboard trio…and beyond! As to the trio sonatas written in a style closer to that of Johann Sebastian, C.P.E. revisited and revised those later in his life in order to distance himself from the Baroque style as much as possible, his own approach becoming stylistically more akin to the lighter, more florid manner of his father’s contemporary, G.P. Telemann. Indeed, it is in his trio sonatas, now written in a lighter style, free from the complex counterpoint and harmony of his father and independent of contemporary fashions, that we follow Carl Philipp Emanuel developing his own style. Some sonatas are revisions of older compositions. Most of the originals are lost. Indeed, in a letter from 1786, Emanuel wrote that he had burnt a large number of older compositions. Concurrent with revising some early trio sonatas (in the 1740’s, when in Berlin, in the employ of Frederick the Great) he composed some new trios which were much more personal in style and clearly different from his older pieces. Performing on two harpsichords, "Bach à Deux Carl Philipp Emanuel Bach Trio Sonatas", DuoChord artists Emer Buckley and Jochewed Schwarz perform a representative selection of these unique works, offering examples of earlier- and later trio sonatas.
Trio sonatas Wq71 and 72, as well as Wq143,
performed here, were written in 1731 when Emanuel was 17, dating back to
the years of study with his father. Emanuel revised them in 1746 and 1747. They exhibit his remarkable creative will, such as in the placement of sudden
pauses, the use of surprising harmonic successions, melodic embellishments,
continuous transformation of a particular motif and abrupt dynamic transitions. Schwarz and Buckley's playing calls attention to J.S.Bach's influence on the works, at the same time,
giving expression to Emanuel's typical fluidity of style, contrasting ideas,
hearty dance rhythms and introspective slow movements. The artists' inclusion
of ornamentation (some written out, some their own) adds much allure to their
playing. The full-blown distinctive stylistic hallmarks of the C.P.E Bach style
– the language of feeling, the essence of the north German aesthetic of Empfindsamkeit,
with the application of the principles of rhetoric in his works and new
ventures into the realm of harmony is obvious in the four Sonatas of Wq75-78.
Here was music that catered to a new public eager for personal expression.
Performing Trio Sonata in C minor Wq78 (1763), Buckley and Schwarz take
on board its conversational dialogue and the composer's personal idiom with
its stylistic daring. They maintain the intensity of the large opening
Allegro moderato with vibrancy and feeling, weaving the Adagio's different
wandering melody and chordal motif elements into one entity of poignancy, then
to give a fiery, vigorous rendering of the challenging Presto, a movement
wrought of long, dovetailed phrases. Their affection for the music is evident
throughout.
And no less affection filters through the
artists' reading of Trio Sonata in D-major Wq151 (1747), originally scored for
flute, violin and continuo. Schwarz and Buckley's playing of the opening
Allegro is exciting, as they maintain the tension of its lively course
throughout, to be followed by a well-disposed, finely balanced reading of the
Largo and culminating with the joyful, playful energy they infuse into the
final Allegro. Wq162 in E major (1749) marks a particularly exemplary case of
Emanuel's mature sonata style and of the fact that he had, indeed, discarded
any and every concession to the then-ruling musical taste, yet still retaining
his ability to compose under the restraints of the court. Buckley and Schwarz's
playing addresses the "otherness" of C.P.E's personal expression,
from the Allegretto's unpredicted twists and turns, through the chromatic
odyssey of the Allegro Di Molto and winding up with the infectious mirth and
cheerfulness of the Allegro Assai.
In his Essay on the True Art of Playing
a Keyboard Instrument (1778), C.P.E. Bach writes: “Play from the soul, not
like a trained bird! …. A musician cannot move others unless he too is
moved…" Jochewed Schwarz and Emer Buckley's articulate playing of
Bach's trio sonatas is bold, articulate, tasteful, intelligent and
discerning. It endorses the growing importance of the composer's personal
feelings and emotions, displays his light, florid and imaginative style and fulfills
the music's call for opulent embellishment. Engaging their undeniable technical
prowess, the artists' playing invites the listener to join them on this journey
through Bach's array of shifting moods, their performance reactive,
conversational and moving.
"Bach à Deux Carl Philipp Emanuel Bach
Trio Sonatas" was recorded at the Paris atelier of Reinhard von Nagel in
2023. Playing from the online edition of the Complete Works of C.P.E.Bach, the
artists perform on two double-manual harpsichords built by Reinhard von Nagel,
each instrument reflecting a distinct historical model and sound world. One is
after an instrument by Christian Kroll, a German-born maker active in Lyon in
the 1770s; it offers a clear, bright and slightly incisive sound. The other,
inspired by two early 18th-century instruments by the German builder Michael
Mietke, features a warmer, rounder tone and a more blended resonance. Together,
the instruments create subtle contrast of colour and character, shaping the
dialogue between the two parts.
