The eight year old Wolfgang Amadeus Mozart received a comission on these sonatas K.10-15, "Op.3", from King George III's consort Queen Charlotte of Mecklenburg-Strelitz (1744-1818). Mozart was granted for these sonatas, which possibly where written before Mozart recieved rhe commission, 50 guineas.
As the basis of the my retypestting of these sonatas I´ve used the 1885 edtion by Breitkopf&Härtel. However, because is seems that most editions excludes the cello part, wich is a addition possibly made for the cello playing King himself, I had to use the Neue Mozart Ausgabe Edition from 1966 (Plath/Rehm) to include this part. I have only used dashed legato slures in cello part to mark that the part is taken from another editon and that it´s optional.
All wedges are replaces by regular stacctato dots as they are in the Breitkof&Härtel edtion.
Concerning the differences in the ranges of the flute and the violin: Since I am definitely not a professional musician myself, and don´t want to tamper with the music, I have left it up to the eventual performers to do whatever he or she wishes.
