Per questa bella mano (Aria for Bass) in D major, K. 612
av Wolfgang Amadeus Mozart
Mozart’s Per questa bella mano (K. 612) is a late, highly original concert aria for bass—completed in Vienna on 8 March 1791—that pairs the singer with an unusually virtuosic obbligato double bass. In a year dominated by large projects (La clemenza di Tito, Die Zauberflöte, and the unfinished Requiem), this compact piece stands out as a witty, theatrical showcase for two specific performers and for the double bass itself.[1][2]
Background and Context
Concert arias occupy a special corner of Mozart’s output: independent vocal showpieces, often written for particular singers, that borrow operatic flair without belonging to a complete stage work. Per questa bella mano (D major, K. 612) belongs to this tradition, but with a twist that makes it instantly distinctive: the bass voice is partnered by an obbligato double bass—a featured instrumental soloist rather than a mere continuo foundation.[1][3]

Mozart’s own thematic catalogue dates the aria 8 March 1791 and indicates that it was written “for Herr Görl and Pischlberger,” generally understood as the singer Franz Xaver Gerl and the virtuoso bassist Friedrich Pischelberger—both associated with Emanuel Schikaneder’s theatrical world in Vienna.[1][4]
In that late Viennese context, the aria can feel like a glimpse of Mozart’s workshop practice: tailored music made quickly, economically, and with a keen sense for the personalities on hand. It is “minor” only in scale, not in invention; indeed, few late-18th-century vocal pieces give the double bass such unapologetic star power.
Text and Composition
The work is an Italian aria for bass in D major, composed in Vienna in 1791—Mozart’s final year (he was 35). The text begins “Per questa bella mano” (“For this lovely hand”), framing a courtly, theatrical situation: the singer addresses a beloved (or benefactor) with flirtatious gratitude and a singer’s instinct for rhetorical emphasis.[3]
Musically, the aria is typically transmitted as a single movement (often labeled Andante) and survives complete in score.[2] Its orchestration is classical and practical, but the scoring makes the point unmistakable: the double bass is not merely present—it is dramatically foregrounded.
Instrumentation (typical scoring):
- Woodwinds: 2 oboes, 2 bassoons
- Brass: 2 horns
- Strings: violins I & II, viola, and a featured solo double bass
- Voice: solo bass
(Exact listings vary slightly by edition and performance practice; the core idea—bass voice with double bass obbligato and orchestra—does not.)[2]
Musical Character
What makes Per questa bella mano worth attention is its bold reimagining of bass virtuosity. The bass singer certainly gets a display piece—warm low notes, patter-like clarity when needed, and a sense of operatic address—but the double bass is treated as an equal partner, answering, ornamenting, and at times stealing the scene with rapid figurations that would normally belong to a violin or cello.[4]
This is more than a novelty. Mozart understood how timbre shapes character: the double bass’s sonority can sound comic, grand, or slyly seductive depending on register and articulation. By putting that color into the foreground, he creates a miniature dramatic duet—voice and instrument—within the frame of a concert aria. The result feels both theatrical (as if lifted from the stage) and knowingly “concertante,” a late-classical delight in which virtuosity becomes a kind of dialogue.
Within Mozart’s late vocal catalog, the aria also illuminates his practical Viennese networks. If Die Zauberflöte reveals Mozart’s genius for large, mixed theatrical worlds, Per questa bella mano shows the same instinct concentrated into a single, unusual partnership—one that still sounds fresh precisely because few composers of the period would have trusted the double bass to sing so conspicuously.
