My pianist Luke was delighted with the K411 adaptation - loves the piece
The next piece I'd like to have a go at is this one. I can dig out / download a copy of the orchestral score online if you like but I realise not only can you but you will understand the slight differences in scores there appear to be (scored for 14 instruments scored fo 13 etc). This copy of the barenreiter seems easy to read https://dme.mozarteum.at/DME/nma/nma_contaudio.php?vsep=113&p1=11&idwnma=5595&drid=7366&pnr=56238
You can even see the original autograph online if you fancy ttps://mmc.kdl.kcl.ac.uk/souvenirs/souvenir-and-expression-in-mozarts-music/w-mozart-masonic-mourning-music-k477/index.html
Same principles - it's about finding a way of preserving the intense moving harmonies for what is an underlying simple melody.
