Solfeggios for Voice (K. Anh.H 20,01–12)
de Wolfgang Amadeus Mozart
Mozart’s Solfeggios for Voice (K. Anh.H 20,01–12) are a small group of short vocal exercises traditionally dated to Vienna in 1782, when the composer was 26. The set is transmitted in several tiny, practical-looking pieces—some with a bass line—and is best understood as studio material rather than a public concert work.
Background and Context
The designation “twelve solfeggios” (K. Anh.H 20,01–12) brings together brief vocal exercises associated with Mozart’s first Viennese years—precisely the period of his marriage to Constanze Weber (1782) and his rapid consolidation as a freelance composer and keyboard virtuoso. Yet the group label can be misleading: the best-documented nucleus is a smaller cluster of Solfeggi catalogued as K. 393 (K³ 385b), preserved in autograph sources and described as “for one voice (and bass)” in the online Köchel catalogue [1] [2]. One leaf even bears the intimate dedication “Solfegio. per la mia Cara Costanza,” suggesting domestic use—practice, teaching, or a singer’s warm-up—rather than publication plans [1].

In other words, even when Mozart’s authorship is secure for individual numbers, the “set of twelve” functions chiefly as a catalog grouping of small-scale pedagogical items circulating under Mozart’s name. The Neue Mozart-Ausgabe’s online platform is the appropriate point of reference for how such pieces are edited and discussed in modern scholarship (musical text alongside critical commentary) [3].
Musical Character
On the page, these solfeggios are compact: single-phrase or short-binary spans designed to drill essentials of vocal line—stepwise motion, arpeggiation, and quick shifts between registers—often with clear tonal orientation (for instance, C major and F major are explicitly given for two numbers in the Köchel catalogue) [1] [2]. When a bass is present (S, B), it is typically functional rather than concertante: a harmonic underpinning that helps a singer internalize cadence patterns and intonation, and that keeps the ear oriented as the soprano line traces scales and broken chords [2].
Musically, the interest lies in how “ordinary” material is shaped with Mozart’s instinct for singability: balanced phrases, clean cadences, and occasional decorative turns that resemble operatic vocal writing in miniature. Heard in this light, the solfeggios sit naturally beside Mozart’s intense preoccupation in 1782 with the voice on stage—most famously in Die Entführung aus dem Serail—but they do so from the workbench, as drills and building blocks rather than as finished theatre.
