In addition to the sax soli I wrote for my arranging class last semester, I also wrote a brass shout chorus. This assignment required parts for four trumpets and four trombones over a 12-bar blues progression. The style was to be loud, punchy, and syncopated.
As mentioned in the sax soli post, I plan to write later about the harmonizing and voicing concepts I learned during this process. Have a listen. They were sight-reading, so be nice.
