It's not jazz. It will take some work to listen to. I think this is my favorite piece from my recital. There were two significant challenges in this prelude. First, both the melody and the counter melody existed in the right hand. The challenge was to play the melody clearly while letting the counter melody sing sweetly over it without overcoming it.
The other challenge was maintaining left hand eighth notes while playing the right hand triplet counter melody (about a third in). It's vintage Rachmaninoff, really. I think it's not a bad performance--probably the best one from my recital, and if you asked me, I could not play it for you today. I still enjoy listening to it though.
