I have no idea which the most beautiful melodies are, but Schubert and Chopin are the first to spring to mind in the context. Rach and Mendelssohn certainly had the gift too.
I think most of my favourite melodies would not come from 88 music. Considering just piano rep, the only thing that comes immediately to mind is the middle section theme of Chopin op 54.
Yeah, I’ve cunzidahed doing one, tbh. There’s an American mofo who isn’t famous but has quite a lot of POOCH parasheeyatz written out, and they’re decent. I can’t remember his name though.
Festin’s got Puccini covered, but why is there a grand total of 1 parazheeyat on Carmen? I saw it on TV a week back, and it just lines up hit song after hit song.
