Emerald Sparrow had already attempted both rhythms for her, and they were double-edged swords. The former could indeed boost morale, but if it affected her too deeply, she would act more recklessly in battle, increasing the consumption of magic power and physical energy; the latter, though it could make someone more focused, would, similarly, if too profound, cause one to forget oneself while completely ignoring the dangers in battle, often getting injured without realizing it.
