Chorus “Viviamo felici” (lost), K. 615
de Wolfgang Amadeus Mozart
Mozart’s Viviamo felici in dolce contento (K. 615) is a lost stage chorus entered in his personal catalogue in Vienna on 20 April 1791. No score is known to survive, leaving only its title, function, and a brief identification of its source as the basis for what can be said with confidence.
What Is Known
The chorus Viviamo felici in dolce contento (K. 615) is documented solely through Mozart’s own thematic work-catalogue (Verzeichnüß aller meiner Werke), where he describes it as a setting “with orchestral accompaniment” of the final chorus from Giuseppe Sarti’s opera Le gelosie villane; Mozart dates the entry 20 April 1791 in Vienna [1] [2] [3]. No autograph, copyist’s manuscript, or early print is presently known, and the music is therefore unavailable for performance.

Placed in the intensely productive Vienna of Mozart’s final year—between court duties, public concerts, and major commissions—K. 615 suggests a practical, theater-adjacent piece: a fresh orchestral dressing of an existing operatic number, likely intended for a specific event rather than posterity [1].
Musical Content
Beyond the text incipit and Mozart’s description of “orchestral accompaniment,” no musical material survives (no melodic incipit, harmony, scoring details, or formal outline). Accordingly, the work’s key, forces, and musical character cannot be responsibly reconstructed from the extant evidence [1] [3].
