Persichetti Exercise 7 - 47 for Brass Sextet

Continuing with the polychordal exercises in Persichetti's "20th Century Harmony" I wrote this Brass Sextet.  The prompt was "2.  Harmonize the following first-trumpet melody in six part brass harmony (three trumpets and three trombones).  Use a predominantly polychordal texture with occasional unison relief."

I chose to use two trumpets, two horns and two trombones instead of the suggested instrumentation.  Thanks for listening and I would appreciate any of your comments!
