Undersong

Undersong was a bardic transmutation spell that conjured a soothing and familiar tune within the mind of the caster.

Effects
As long as the bard kept this song in their head, and hummed along with the melody, they experienced a sensation of focused concentration. Its effects lasted for a matter of minutes, depending on their experience and skill as a performer.

Components
This spell only required verbal utterances to cast.

History
Tvash-Prull developed spells for bards. In his one and only symphony he magically embedded this and other spells in the sheet music for it to be discovered by bardic spellcasters who had the ability to detect and decipher the spells.
