A few months ago, I released a video on YouTube called "The Danger of Orchestration Classes in America," in which I expose some of the many pesky reasons why composers leave American conservatories without the necessary skillset to orchestrate. I am making a shorts series out of this, you can check out the first one, in which I talk about the need to orchestrate the bass (something I never heard discussed in my very expensive studies in America 😀). Best of luck with your orchestrations, Barney
