[22] This name is not in Mendel, Riemann, Grove, nor Brown. Fétis, however, mentions him as Joseph Umstadt, maître de chapelle of Count Brühl, at Dresden, about the middle of the eighteenth century, and as composer of Parthien, and of six sonatas for the clavecin.
[23] See, however, the early Würtemberg sonatas.
[24] Examples to be found in Rolle, Müthel, and Joh. Chr. Bach, etc.
[25] Gluck's six sonatas for two violins and a thorough bass, published by J. Simpson, London (probably about the time when Gluck was in London, since he is named on title-page "Composer to the Opera"), have three movements: slow, fast, fast,—the last generally a Minuet.
[26] E. Bach did some strange things. One of his sonatas (Coll. of 1783, No. 1) has the first movement in G major, the second in G minor, and the third in E major.
[27] Galuppi, No. 4, first set: Adagio, Spiritoso, Giga Allegro.
[28] Sometimes the last movement was a Tempo di Menuetto, a Polonaise, or even a Fugue.
[29] Wagenseil's Op. 1, Sonatas with violin accompaniment. No. 4, in C, has Allegro, Minuetto, Andante, and Allegro assai.
[30] As this experiment of Seyfert and Goldberg, in connection with Beethoven, is of special interest, we may add that Goldberg has all the movements in the same key, but Seyfert has both the Trio of the Minuet, and the Andante in the under-dominant. This occurs in two of his sonatas; in both, the opening key is major.
[31] There is, however, one curious exception. The first of the two "Sonates pour le clavecin, qui peuvent se jouer avec l'Accompagnement de Violon, dédiées à Madame Victoire de France, par J.G. Wolfgang Mozart de Salzbourg, agé de sept ans," published at Paris as Op. 1, has four movements: an Allegro in C (with, by the way, an Alberti bass from beginning to end, except at the minor chord with organ point near the close of each section, the place for the extemporised cadenza), an Andante in F (Alberti bass from beginning to end), a first and second Menuet, and an Allegro molto, of course, in C. The brief dedication to Op. 1 is signed:—"Votre très humble, très obéissant et très petit Serviteur, J.G. Wolfgang Mozart."
