No arranger was named on the 1793 first edition of this piano version of the slow movement from Mozart's last chamber work for strings, but Alfred Einstein was so impressed by the adaptation that in his Mozart biography he ventured, "it is so masterly that one might even imagine the hand of Mozart to be present". The many dynamic, tempo and articulation markings added by the arranger not only make this fine music particularly suitable for fortepiano or clavichord, but will also be of interest to modern string players performing the original version.

“Whoever was ultimately responsible for the arrangement has been successful in the transference from strings to keyboard, creating a piece that offers much recreation and not a few challenges, which would make a most felicitous addition to a concert.”
