Melody in F Anton Rubinstein

Anton Rubinstein - Melody in F

I have listened to this piece, people playing piano, flute, orchestra, trumpet, organ etc. And everyone have their own way in choosing tempo, some very slow, some very fast…..
I made tempo changes to make it more interesting to listen to. I tried to play it slow but to me it was boring….I don’t know much about the art of musical interpretation and how to apply it, but I played as I felt, feeling creative.
The sounds at the end is a celesta and church bells (from Pianoteq).
