Music -$0. We have all music on hand and most is in the public domain.
Drill - $12 - I have to spend $12 on the drill pad to write our drill on. I write the drill myself.
Uniforms - $0 per year. We own uniforms.
Props - $0. I'm Military, what are props?
Electronics - $0. See above answer.
I say all this in jest, but seriously, some schools in my area spend $10k+, and I'm only a 4A.
Perhaps we divide the band world into Division 1 and Division 2, with the line of demarcation between a certain budget amount in each class? Say over $8k for 1A, over $10k in 2A, $12k in 3A, $14k in 4A, $18k in 5A, and $25k in 6A, total expenditures on music, drill, props, choreography, etc? Excluding travel?
