It is in the 2nd volume of Piano Sonatas, as Anhang II Nr.1 (page 173).
Briefly stated this 25 measure movement in C stands on the first page of the autograph with the later composed final chorus of the Grabmusik K42/35a, however the piano movement is crossed out--apparently by Mozart himself. According to Wolfgang Plath its probable origin time is 1771 in Salzburg. In a 1986 article Wolfgang Rehm states the fragment is in connection with the 4 Piano Sonatas known only by their incipits (K.Anh 199-202/K6 = K33d-g).
