As of right now, I am only 6 chapters away from completing A Course on Band Orchestration. The initial draft should be complete within the next few weeks. All that’s lacking now are chapters where I need to do full band transcriptions, which will take some time to complete.
If you haven’t done so already, please support the project at https://www.gofundme.com/bandestration
Not only will this help me out, it will reserve your copy of the book before I publish it.
