Beethoven composed works in the popular vein just as industriously as he created his most soul-searching and original masterpieces of “art” music. Every famous and not-so-famous composer of his day, as in preceding generations, considered improvising or writing sets of variations practical tools of the composer’s art. Beethoven’s skill at improvising on a theme given to him on the spot was legendary, but he was also enough of a businessman to know that writing down and publishing variation sets was a lucrative business, especially if the varied theme were a popular tune from an opera that was making the rounds. Beethoven especially admired Mozart’s operas, though he was equally adept at varying less elegant themes, thereby rescuing them from ultimate obscurity.

In the 1790s Beethoven had composed variations on tunes from three great Mozart operas: “La ci darem” from Don Giovanni for two oboes and English horn, “Se vuol ballare” from Le nozze di Figaro (The Marriage of Figaro) for violin and piano, and “Ein Mädchen oder Weibchen” from Die Zauberflöte (The Magic Flute) for cello and piano. In 1801 he was again drawn to The Magic Flute—and the same cello-piano combination—this time for a set of variations on “Bei Männern, welche Liebe fühlen” (A man who feels love), originally an exquisite duet between the comic birdcatcher Papageno and Princess Pamina. Beethoven’s immediate stimulus was probably a revival produced around that time by Emanuel Schikaneder, the opera’s librettist and original portrayer of Papageno.

Beethoven’s manuscript for the “Bei Männern” Variations shows a crossed-out dedication, probably to Countess von Fries, whose husband had just received the dedication of the Violin Sonatas, opp. 23 and 24. Evidently changing his mind, the composer inscribed the work instead to Count Johann Georg von Browne-Camus, whom Beethoven had described as “the Maecenas of my Muse” in the dedication of his String Trios, op. 9. Beethoven dedicated a number of works to the count, whose generosity extended even to presenting him with a horse for dedicating to his wife the Variations on a Russian Dance from Wranitzky’s “Das Waldmädchen.”

As in many of his variation sets, Beethoven follows tradition by including variations of contrasting tempos and characters, a minor-key variation, and an elaborate and extended final variation. He preserves Mozart’s tender quality in the presentation of the theme—even suggesting the two singing roles by switching the melody between the piano right hand and the cello. He does, however, leave the stamp of his personality by making some subtle, fascinating changes in Mozart’s rhythm and articulation.

The quiet but sprightly first variation breaks the mood and immediately shows that piano and cello are to be equal partners as they begin in counterpoint. The virtuosity for both is stepped up in the next variation, whereas the third calls for sweetness and grace. Variation 4, the minor-mode variation, presents a haunting kind of melancholy, featuring the cello in its lower range. The capricious fifth variation provides a foil both to this and to the Adagio variation that follows. Here the tenderness returns with an added layer of poignance and elegant figuration. The extended final variation offers a procession of characters from dancelike to stormy, and injects a last moment of reflection just before the energetic concluding chords.
