Fist of all I must ask, is this your composition? If so, Beautiful orchestration.. Beautiful arrangement.. Are you a fan of Josef Haydn? I'm hearing a lot of that in your work.
Year late on the response—sorry. Yes, it's my work. Mostly I just post scraps here or projects I write for practice. This falls under the latter category. I don't have any particular fondness for Haydn above any other composer, but it's easy (and good practice) to ape the elements of his style.
Please contact me if you would like to use this in a project. We can discuss the details.
