twelve parts, under the title _Oeuvres mêlées_ (twelve books, each
containing six sonatas), was published by Haffner at Würzburg,
somewhere between 1760 and 1767. And another collection of symphonies
and sonatas, principally by Saxon composers, was published at Leipzig
in 1762 under the title _Musikalisches Magazin_. We will give the
names of some of the chief composers, with titles of their works,
adding a few other details. It is difficult in some cases to ascertain
the year of publication; and it is practically impossible to say when
the sonatas were actually composed:--

BACH, Wilh. Friedemann. Sei sonate, No. 1,[19] D
major (Dresden, 1745). Sonata in C (published in Litolff's
_Maîtres du Clavecin_), and others in D and G (autographs),
and in F, A, and B flat (manuscripts).

BACH, Joh. Ernst. Two sonatas (in _Oeuvres
mêlées_).

NICHELMANN, Christoph. Sei brevi sonate, etc., Op.
2; Nuremberg (between 1745-1756).

HASSE. Two sonatas in E flat and B flat
(manuscript; on one is the date of 1754). Two sonatas, one
in D minor (only one Lento movement); the other in D major
(only one Allegro movement in old binary form). These are
both in the Leipzig collection named above.

BENDA, Georg. Sei sonate (Berlin, 1757). Sonatas in
G, C minor, and G, also seven sonatinas (Vermischte
Clavierstücke, Gotha, 1780).
