Thank you for the great feedback!
Interesting feedback, perhaps I'm more open to a style like this, however it would be described. Certainly influence from composers such as Stravinsky as well as many others and jazz harmony influence. Someone on another forum described the piece as a ballet, I thought that was flattering, it was kind of that idea I had although the term ballet never entered my mind. It's true the idea of making a kind of symphonic poem around a tennis match may sound strange, but that was the challenge, and I must admit if I didn't play the sport, it wouldn't be the same, the passion I have for the sport was the main driving force in the creation process. I'm only a club player though and my backhand is not as impressive as what we hear in the piece. :) I think it might be a fun piece for orchestra to perform, despite the massive percussion section.
ps I will also be doing a screencast.
