Johann Sebastian Bach’s Goldberg Variations stand as one of the most searching journeys in all keyboard music, a work in which intellectual rigour, dance, humour, and spiritual introspection coexist within a single unfolding arc. The piece invites listeners to experience transformation not through changing keys or overt drama, but through the reimagining of a single harmonic pattern over the course of an evening.

Bach’s “Keyboard Exercise,” not a legend
Published in 1741 as the fourth and final volume of Bach’s Clavier-Übung (“Keyboard Exercise”), the Goldberg Variations appear under the modest description “an aria with diverse variations for the harpsichord with two keyboards,” composed “for the delight of the souls of lovers of music.” The familiar anecdote that Bach wrote the work to soothe the insomnia of Count Keyserlingk, with the young Johann Gottlieb Goldberg playing at the count’s bedside, surfaces only decades later in a biographical account and remains impossible to verify.

Whatever the truth of that story, the music’s nocturnal, reflective character in certain variations has encouraged generations of listeners to imagine it in intimate, late-night surroundings. Yet the work is just as much a public monument as a private solace: it crowns Bach’s lifelong engagement with variation technique, counterpoint, and large-scale musical architecture.

Architecture: order inside freedom
At its core, the Goldberg Variations are not variations on the surface melody of the opening Aria, but on its 32-bar bass line and harmonic progression. This ground bass—derived from patterns that were common currency in the Baroque and closely related to basses known from Handel and others—runs unchanged through all thirty variations, acting as a silent structural spine even when it is not explicitly stated.
​

The work consists of 32 movements in total: the initial Aria, thirty variations, and the return of the Aria at the end. Bach arranges the variations in ten groups of three, with every third variation a canon, and with the interval between the canonic voices expanding systematically from unison (Variation 3) to the ninth (Variation 27). Between these canons are character pieces of astonishing variety—toccatas, dances, fughettas, and hand-crossing showpieces—that together create a sense of both inexhaustible fantasy and underlying order.

Aria — A serene, ornate sarabande in G major that provides the harmonic foundation for everything to come. Its melody floats above a steady, purposeful bass.
Variation 1 — A sprightly, syncopated opening that contrasts sharply with the Aria’s tranquility — like drawing back a curtain.

Variation 2 — Three interweaving voices in a compact, elegant dance; two parts converse playfully over a steady bass.

Variation 3 (Canon at the Unison) — The first canon: one voice follows the other at the same pitch, a beat later, in a lilting 12/8 dance rhythm.

Variation 4 — A lively passepied-style dance in quick triple time, with imitation between the parts.

Variation 5 — The first of the “arabesques”: a dazzling, rapid-fire piece featuring spectacular hand-crossing, as one hand leaps constantly over the other.

Variation 6 (Canon at the Second) — A tender, nostalgic canon where the following voice enters a step higher. Kirkpatrick called it “almost nostalgic tenderness.”

Variation 7 — A gentle gigue — a French-style dance with dotted rhythms, unhurried and graceful.

Variation 8 — More virtuosic hand-crossing, this time in the French style, with both hands occupying the same register simultaneously.

Variation 9 (Canon at the Third) — The canon entries are now a third apart, with a slightly more active bass adding warmth.

Variation 10 (Fughetta) — A miniature four-voice fugue, the subject winding through bass, tenor, soprano, and alto in turn.

Variation 11 — A brilliant toccata in compound time: scales, arpeggios, and trills cascade across both hands.

Variation 12 (Canon at the Fourth, inverted) — A canon in contrary motion — the follower moves in the opposite direction to the leader.

Variation 13 — A slow, richly decorated sarabande for two manuals; the right hand sings a long, ornate melody while the left accompanies gently.

Variation 14 — Rapid toccata featuring enormous leaps between registers; Glenn Gould called it “one of the giddiest bits of neo-Scarlatti-ism imaginable.”

Variation 15 (Canon at the Fifth, inverted) — G minor — The emotional turning point of the first half: the only minor-key variation so far, slow and achingly melancholic. Gould likened it to “a perfect Good Friday spell.”

Variation 16 (French Overture) — A grand, ceremonial opening to the second half, featuring bold dotted rhythms and a fugal contrapuntal section — unmistakably French in character.

Variation 17 — Another lively toccata for two manuals — light, skittish, and brilliantly keyboard-idiomatic.

Variation 18 (Canon at the Sixth) — A confident, tightly argued canon full of suspensions; Nicholas Kenyon called it “among the most supremely logical pieces of music ever written.”

Variation 19 — A dance-like piece in 3/8 with a flowing sixteenth-note figure passed gracefully between three voices.

Variation 20 — A virtuosic toccata for two manuals, one hand plucking short notes against the other’s long lines, in rapid hand-crossing.

Variation 21 (Canon at the Seventh) — G minor — The second minor-key variation, somber and almost tragic; a slow lament bass underlies the two canonic voices.

Variation 22 (Alla breve) — A stately four-voice movement, almost fugue-like in texture; the foundational bass line of the whole work is heard here more plainly than almost anywhere else.

Variation 23 — The hands chase each other in rapid, playful interplay — scales shooting up and down, alternating between hands in sparkling bursts.

Variation 24 (Canon at the Octave) — A lilting canon in 9/8; unusually, the leader alternates between voices mid-section.

Variation 25 — G minor, Adagio — The emotional pinnacle of the entire work. Wanda Landowska called it “the black pearl.” Chromatic, wistful, and achingly beautiful, it is the longest and
slowest variation, and the third and final one in minor.

Variation 26 — A sudden burst of joy after the introspection: a racing sarabande in two simultaneous time signatures, the melody sparkling over a rhythmic accompaniment.

Variation 27 (Canon at the Ninth) — The final canon, and the only one written without a bass line — pure, stripped-down, two-voice counterpoint.

Variation 28 — A dazzling toccata filled wall-to-wall with written-out trills in both hands, the two voices glittering in and out of each other.

Variation 29 — Grand and declaratory: heavy chords alternate with brilliant arpeggios shared between the hands, building a sense of majesty and resolution.

Variation 30 (Quodlibet) — Instead of the expected final canon, Bach surprises us with a quodlibet — a cheerful medley of popular folk tunes woven over the bass line. The two songs embedded here translate roughly as “I’ve been away from you so long” and “Cabbage and turnips have driven me away — had my mother cooked meat, I’d have stayed!” It was a favourite party game of the Bach family, and feels here like a warm, affectionate farewell.

Aria da Capo — The opening Aria returns, note for note — but after everything we’ve heard, it sounds transformed: familiar yet distant, like returning home after a long journey.
