Aria for Soprano, “Non curo l’affetto” in E major (K. 74b)
ヴォルフガング・アマデウス・モーツァルト作

Mozart’s “Non curo l’affetto” (K. 74b) is a brief soprano aria in E major, written in northern Italy around late 1770 to early 1771, when the composer was about fifteen. Likely intended for performance in or near Pavia (and sometimes associated with Milan), it sets a text by Pietro Metastasio from Demofoonte and shows Mozart already fluent in the stylized emotional rhetoric of opera seria [1] [2].
Background and Context
In early 1771, Wolfgang Amadeus Mozart (1756–1791) was still in the orbit of his first Italian journeys, absorbing the practical theatre culture of Milan and nearby cities. “Non curo l’affetto” (K. 74b) is a self-standing aria for soprano and orchestra—one of the many single numbers that circulated for academies or for insertion into existing stage works rather than as part of a fixed “Mozart opera” in the modern sense [1].

The text is by Pietro Metastasio and is drawn from Demofoonte (Act I, scene 7), where Creusa dismisses the “timid lover” who trembles at the sword but talks boldly of love [2]. Surviving source descriptions connect the aria with “il teatro di Pavia” and date it to 1771, while cataloguing also places it broadly in Milan between December 1770 and January 1771 [1].
Musical Character
Marked Allegro, the aria is conceived as an opera-seria “aria of disdain” (aria di sdegno), with a bright, forward E-major profile that suits its tone of derision and defiance [2]. The orchestration is compact but pointed—soprano with strings plus two oboes and two horns—typical of the Italian theatre palette available to the teenage Mozart [1] [2].
Within this conventional frame, the vocal writing is reportedly demanding: extended runs and display passages do much of the dramatic work, turning contempt into virtuoso energy rather than sustained lyric reflection [2]. One also hears the young composer testing contrast—sources describe a more inward minor-key middle span accompanied by strings alone, a quick shift of colour that sharpens the character’s sarcasm before the bright surface returns [2].
