You know how to use music to inspire courage and counter hostile musical effects.
Benefit: You can use the power of music to either inspire courage or countersong for a number of rounds per day equal to 2 + your Charisma modifier as if you are a 1st-level bard using the bardic performance ability. If you have at least 10 ranks in Perform the number of rounds per day increases by 2. Each round, you can choose to use either one of inspire courage or countersong.
Starting a performance is a standard action, but it can be maintained each round as a free action. Changing a performance from one effect to another requires you to stop the previous performance and start a new one as a standard action. A performance cannot be disrupted, but it ends immediately if the you are killed, paralyzed, stunned, knocked unconscious, or otherwise prevented from taking a free action to maintain it each round.
