Most Baroque works we call "trio sonatas" were (it seems) called "sonatas" by their composers, and absent good evidence that "trio" was a contemporary name for them and not a later attachment, this is how we tag them. The early (18th-century, judges the Library of Congress) copy that does in fact so name it is probably sufficient to the task, though; the ca.1763 copy made partially by his brother Johann Christian, partially by an anonymous Halle copyist, held by S.A. Berlin, even moreso. - Schissel (note: the Zimmermann edition is mentioned as having been used for a concert in 1935 or so, in a contemporary (that is, 1935-or-so) issue of "The Sinfonian of Phi Mu Alpha".)
