My friend Wayne Markworth, retired band director from Centerville HS (OH) and a member of the BOA Hall of Fame, recently updated his web site, Shadow Lake Music. He also has an attached blog and on it he talks about marching band show planning. If you are engaged in such a process right now, you will certainly want to check it out. His book, The Dynamic Marching Band, is also excellent, and I recommend it to you very highly.
Oh, and some guy I know wrote this book on marching band arranging you might want to take a look at, as well. Even if you don’t arrange, there is a lot there about show planning and what to tell your arranger. If you buy stock charts for your show, you may want to review the book anyway so that you can choose wisely.
Don’t be that guy.
