2 (return) [ This rondo (373 K.) was composed, according to the autograph, on April 2, 1781, for Brunetti; it is in C major (allegretto grazioso 2-4,) accompanied by the quartet, two oboes, and two horns, and is simple and graceful without much demand of execution.]
3 (return) [ The unfinished allegro movement in B flat major (372 K.), begun on March 24, 1781, probably belongs to this sonata, which was not afterwards written down.]
4 (return) [ The words of the rondo (374 K., Concertarien, No. 5), "A questo seno," appear to have been taken from an opera called "Zeira." A short recitative introduces the rondo, of which the theme is thrice repeated and closes with a coda. The song is simple throughout, without any passages, and for a voice of moderate compass; the accompaniment (the quartet, two oboes and two horns) is also easy. It is plain that Ceccarelli was a singer of no pretensions. The cantilene, however, is expressive, and there are some original harmonic touches.]
5 (return) [ The mother of the composer, at that time prima donna at the German Theatre (Jahrb. d. Tonkunst, 1796, p. 69).]
6 (return) [ "The Imperial Councillor, Von Braun, is one of our greatest musical connoisseurs. He thinks very highly of the compositions of the great Ph. Emanuel Bach; and here he is opposed by the majority of the public in Vienna." (Nicolai, Reise, IV., p. 556.)]
7 (return) [ There was a chorus of 200 voices for Dittersdorf s "Esther," 1772 (Selbst-biogr., p. 203). K. R[isbeck] speaks of 400 assistants (Briefe, I., p. 276).]
8 (return) [ At his concert in Leipzig he played these variations again after an improvised fantasia (354 K.).]
9 (return) [ Neue Wien. Musikzeitg., 1852, No. 35.]
10 (return) [ So it had been promised (Vol. II., p. 65); but Mozart asserts repeatedly that he only had a salary of 400 florins (Vol. II., pp. 176, 181).]
11 (return) [ The representations of Aloysia's mother, which Mozart afterwards learned to receive with caution, may have had some influence on his judgment of Aloysia. The account given by her husband, Jos. Lange, is very different. He narrates in his autobiography (p. 116) that they conceived an attachment for each other soon after Aloysia's arrival in Vienna: "She had the misfortune to lose her father by a fit of apoplexy. Her inconsolable grief, and my care for her family, drew us closer together; my sympathy lightened her sorrowing heart, and she consented to marry me, hoping to find in her husband the friend she had lost in her father. As she had contributed to the support of her family by the exercise of her talent, she continued to make her mother an annual allowance of 700 gulden, and paid her an advance of 900 gulden which had been made to the family by the court."]
