Your songs continue to inspire allies long after your words have faded.
Prerequisite: Perform (any one) 25 ranks, bardic music class feature.
Benefit: The effects of your bardic music inspiration abilities last for ten times as long as normal after you stop singing. This has no effect on inspiration abilities that have no duration after you stop singing (such as inspire competence).
