Sound off

Sound Off is the trooping of the line done by the band during a military parade or review. Sound Off music is a three- chord ( tonic, dominant seventh, tonic) cadence that precedes and follows the march performed for the Sound Off sequence. The preceding Sound Off chord cadence is performed in the same key as the beginning of the music. The second Sound Off chord cadence is performed in the key of the music at the time of the cut off.
