I have only played the Ghost Trio Op.70 No.1, and it was pretty straightforward. I would say the Beethoven's piano trios are rather generally straightforward to play.Especially if you compare them to the massive trios like Tchaikovsky! If you want really easy though, then Op.1 No.1 is quite easy.Edit: I meant playing the trio has a whole, and not specifically referring to the piano parts. I was the cellist.
Actually, I'm looking for a piano trio that has an "easy" piano part, because bothe the violinist and cellist are REAALLY good
OK - well try the one by Max Reger, then (Op. 102 for piano, violin and cello, not Op. 2 for piano, violin and viola, that is)...Best,Alistair
