115: Cello Suite 4

 Johann Sebastian Bach’s *Cello Suite No. 4 in E-flat major*, BWV 1010, represents one of the most distinctive and conceptually challenging works within the set. Where the Third Suite in C major projects outward with brilliance and resonance, the Fourth turns toward a more complex and, at times, enigmatic sound world. The choice of E-flat major—a key less naturally aligned with the cello’s open strings—immediately alters the instrument’s response, producing a denser, more veiled sonority. This shift is not merely technical; it shapes the suite’s entire expressive character. The music feels more constructed, more deliberate, and often more introspective, even in its moments of grandeur. Bach seems to be testing not only the limits of the instrument but also the performer’s ability to sustain coherence within a less naturally resonant tonal environment.

The technical demands of BWV 1010 are inseparable from its musical identity. The suite frequently requires extended use of higher positions, complex string crossings, and sustained control over tone in less comfortable registers. Chordal writing and implied polyphony take on a more intricate role, often requiring the player to articulate multiple voices within a compressed and sometimes resistant texture. Unlike the more idiomatic fluency of the earlier suites, here the difficulty itself becomes expressive: the sense of effort and negotiation is embedded in the music’s character. The performer must not only overcome these challenges but integrate them into a convincing musical narrative, preserving continuity where the instrument does not naturally provide it.

Composed, like the other suites, during Bach’s Köthen period, BWV 1010 reflects a deepening engagement with the possibilities of solo instrumental writing. Yet rather than expanding outward in purely extroverted terms, Bach turns inward, exploring how complexity and constraint can generate new forms of expression. The suite occupies a unique position within the cycle: it neither retreats into the stark austerity of the Second Suite nor embraces the open resonance of the Third. Instead, it inhabits a middle ground where density, abstraction, and structural rigor come to the forefront.

The Prelude immediately signals this departure. Its opening gestures are bold yet harmonically intricate, unfolding in a series of broken chords that feel less like natural arpeggiation and more like deliberate construction. The range is wide, and the movement frequently ventures into higher registers, creating a sense of vertical expansion that contrasts with the more grounded sonority of earlier preludes. As the music progresses, sequences build tension through repetition and variation, but the resolution often feels deferred or subtly obscured. The performer must carefully articulate these structures, ensuring that the harmonic direction remains perceptible despite the complexity of the surface.

The Allemande continues this sense of intricacy but in a more restrained and introspective manner. Its lines are dense and often highly ornamented, requiring precise control to maintain clarity. Unlike the flowing ease of the Third Suite’s Allemande, this movement feels more deliberate, with phrases that unfold through careful negotiation of the instrument’s limitations. The rhythmic profile is steady, but the internal subdivisions create a subtle sense of tension. Expressively, the movement balances dignity with introspection, inviting a reading that emphasizes its underlying structural coherence rather than overt lyricism.

The Courante introduces a more animated character, though it retains the suite’s overall complexity. Its rhythms are lively, often incorporating hemiola-like patterns that blur the sense of metric stability. The lines are intricate and require a high degree of precision, particularly in navigating rapid passages that span multiple strings. Despite its energy, the movement does not feel carefree; instead, it conveys a kind of controlled vitality, where motion is constantly shaped by the demands of articulation and balance.

The Sarabande stands as the emotional center of the suite, notable for its relative sparseness. In contrast to the richer textures of the surrounding movements, Bach pares down the writing to a more austere, almost exposed line. This simplicity, however, is deceptive: the implied harmonies are subtle, and the expressive weight falls heavily on the shaping of each note. The emphasis on the second beat is present but understated, integrated into a broader sense of stillness and reflection. The performer must sustain a sense of continuity and depth with minimal material, allowing the music’s quiet intensity to emerge without exaggeration.

The Bourrées provide a contrasting pair that reintroduces a more grounded, dance-like character. Bourrée I is assertive and rhythmically clear, offering a sense of stability after the introspection of the Sarabande. Its phrases are more direct, though still shaped by the suite’s overall density. Bourrée II, typically set in a contrasting tonal area, lightens the texture and introduces a more transparent, almost pastoral quality. The return of Bourrée I restores the initial character, creating a structural symmetry that reinforces the suite’s architectural balance.

The Gigue concludes the suite with a movement that is both lively and structurally intricate. Its rhythmic patterns are animated, often emphasizing compound groupings that propel the music forward. At the same time, the lines are tightly constructed, requiring careful articulation to maintain clarity. Unlike the more exuberant Gigues of the earlier suites, this one retains a sense of restraint, its energy shaped by the same underlying complexity that defines the work as a whole. The conclusion feels decisive, but not overtly triumphant; it resolves the suite’s tensions without fully dispelling its introspective character.

BWV 1010 occupies a distinctive place within Bach’s cello suites, representing a turn toward greater abstraction and structural density. It challenges both instrument and performer to operate beyond the boundaries of natural resonance, transforming technical difficulty into expressive substance. In this sense, the Fourth Suite deepens the trajectory established by its predecessors, demonstrating how limitation can become a source of creative expansion. The cello, here, is not merely a vehicle for resonance or brilliance but a medium through which Bach explores the interplay between constraint, complexity, and expressive depth.

54: Trills in the Baroque vs. Classical Periods

Image
Baroque music is known for its incredibly technical and ornamented style. The most common and fundamental of those ornaments is our focus today: the trill. Most simply, a trill is a very fast, repeated alternation of two notes. In the vast majority of cases, those notes are adjacent, but that is not a requirement. Given how fast and common they are, regardless of what you play—whether it’s a string, wind, or keyboard instrument, or your voice—they have a reputation for being quite tiring to play. The period matters when considering a trill. Classical and later composers treat trills, in a sense, in the opposite manner than Baroque composers do. Let me show you two examples: First, the Baroque way of thinking. This is a PAC:   and especially in the Baroque era, when the plucked harpsichord dominated over the hammered piano, it was hard to sustain sounds for long since the sound of the plucking decays quickly. The trill was developed in response, out of a need both to ornam...

35: Figured Bass

Image
  There’s a system of notating harmonies that’s rather unique to the Baroque era, but which is so frequently used there, and so important to it, that no discussion of theory would ever be complete if we did not cover it. This is the notation of figured bass: “figured,” in the sense of using figures (numbers) to notate the bass. Figured bass was, in a sense, its own notation completely separate from the five lines and four spaces of the staff, which was nearly exclusively the purview of cellists, bassists, harpsichords, and organists.  Figured bass, fair warning, can be intimidating at first. But, just as with anything else we’ve covered so far, the more you practice reading it, the better you’ll get.  In this system, we use numbers to indicate intervals above the bass. We stack them, and this is how we build chords. If you can’t stack them, nowadays, it’s perfectly fine to use slashes and write the numbers horizontally.  Let’s start with the easiest figured bass nota...

102: Wagner (who was terrible, in case you didn't know), Tristan, and French Sixths

Image
 Let’s turn our attention to one chord—yes, one literal chord, not one class: F-B-D#-A. The original context that made this “The Chord” that everyone talks about—the reason this opera is as famous as it is—is its inclusion in Richard Wagner’s “Tristan and Isolde.” The whole opera lasts just shy of four hours, but it’s most remembered for this one chord. Here it is, in red, from the Wikipedia article about the opera, during which a hugely significant amount of time is spent just talking about this single chord. It almost cannot be overstated how important this chord was to the development of music in the late 1800s and early 1900s.  Some have said—again, referring to quotes in the Wikipedia article—that the power of this one chord in the late 1800s was the same as the transformative power of Beethoven 3 or 9 in the first part of the 1800s; I don’t think that’s hyperbole in the slightest. Deplorable as his personal politics were (he was violently antisemitic and the favorite com...
