This is a set of variations built over a repeating ground bass. The underlying structure is repetitive, significantly less complex than Bach's Italian Concerto. The technical and musical challenge lies in refined articulation, clear musical differentiation between sections, control of embellishments, and consistency of the recurring bass pattern. Encourage students to hear each variation as a new musical event rather than allowing the repeated material to become routine or static.
This is clearly music conceived for the harpsichord, and the articulation should pay homage to that style. Work with student on sound: encourage them to listen for clarity, buoyancy, and definition of touch rather than relying on sustained piano sonority. With each repeat of the bass, the character and sound changes, thus encourage your students to recognize these shifts aurally, so that the form remains clear in performance.
The recurring bass line should remain rhythmically steady and stylistically consistent from one variation to the next. Have students practice the bass independently so that its shape and pulse become completely secure. At the same time, strive to keep the two strands within the left hand independent and clearly differentiated. This can be achieved through a subtle combination of dynamic balance, articulation, and careful observance of longer note values. Holding longer notes for their full duration is particularly important in preserving the illusion of two distinct contrapuntal lines rather than a single block of accompaniment.
Encourage the student to “assign” different instruments or timbres to individual voices. This can be especially helpful in maintaining the illusion of independence between the bass, tenor, and upper melodic lines. A student at this level should begin to understand how imagined instrumental colors can inform texture, balance, articulation, and dynamics. If this is not yet part of the student’s interpretive vocabulary, this piece is an excellent whetstone for developing that skill.
With Baroque repertoire, the question of how closely the printed score reflects the original source is always worth considering. In the absence of a definitive Urtext edition, compare several editions when questions arise regarding notes, ornamentation, articulation, or voicing. Reputable recordings can also provide useful interpretive context, particularly when several respected performers make similar choices. This is great for a discussion about distinguishing between what is clearly supported by the score, historical performance practice and what belongs to the performer’s interpretive discretion.
Some performances introduce the texture gradually: first presenting the bass alone, then adding the tenor, and finally bringing in the remaining voices. For MMTA Contest purposes, I would not recommend altering the opening in this way if it departs from the prescribed score. In a recital, however, this kind of gradual introduction can be a historically informed and musically effective interpretive choice. It can also help students understand the underlying construction of the piece by allowing them to hear how the contrapuntal layers accumulate.
Use pedal very sparingly—more as a safety net than as an integral part of the sound. Because articulation and textural clarity are paramount, the student should be able to project the musical lines convincingly without relying on pedal. If pedal is used at all, it should support connection or resonance discreetly, never blur the independence of the voices or soften the crispness of the articulation.
Measures 6-7: These embellishments are technically intended to be realized in the same manner. However, in keeping with Baroque performance practice, beginning an ornament on the upper auxiliary can be awkward when it results in an immediate repetition of the preceding note.
To avoid this, I have altered a couple of the turns to begin from below instead. See the highlighted pencil markings in the example above. This preserves the flow of the ornament while avoiding an unnecessary repeated note.
Measure 15: To keep embellishments consistent, I am usually adding this quick turn, as shown in the highlighed image above.
Measure 20: A natural sounds wrong. All recordings here have A-flat.
Measures 32-33: C on the bottom of the RH chord on the last 16th of Measure 32 is odd, as it is not repeated on the downbeat of Measure 33. I usually just remove it.
George Malcolm, Harpsichord. Theatrical and vivid.
Alexander Malofeev. A beautifully poetic and finely layered performance, with remarkable control of voicing and color; the repeated ground never feels static, but continually changes character as the texture unfolds. Note that his performance begins with stating the bass line first, before launching into the variations.
Vadym Kholodenko. Notably faster and more technically forward than Malofeev's interpretation, it is yet wonderfully nuanced and captures the improvisatory air.
