Just some ideas:I would personally play the Schumann as the first piece. Of course it may not be comfortable to play such a big piece first, but I have heard it done by Zimerman and Pollini ( and maybe Cziffra but I can't really remember for sure) and it worked out really well.Then (and this is just an idea):BachChopin RachLisztBach is often considered good as a first piece. And Liszt would work (imo) well as an ending piece because it has much bravura.Is all of this for one recital? It seams quite big!
I feel this order:Schumann Sonata in F# min op 11JSBach Partita in G Major No. 5Rachmaninoff Corelli VarsChopin BarcarolleLiszt Spanish RhapsodyRavel PavaneLovely program btw, the Schumann is imo the most difficult to play convincingly (I have been bored to tears listening to poor interpretations in concert and fought to remain awake) and if you play it well you will have them eating out your hands throughout the rest. It is a huge ask of an audience a Schumann Sonata, huge demands on the performer to keep the audience with them because it is so easy to lose them (it is easy to drone on and on while playing some of Schumann's lines).
