Oklahoma Bandmasters Association
State champions
OBA finals winners by class, largest class first.
2000 to now
Finals winners only: where a class had prelims and finals, the finals winner is the champion (the contest pages show both). Before 2014, 6A was one class, shown under 6A1. A dash means the class didn't exist that year.
Before 2000
Classes were combined until 2000, so these years have their own columns.
