Tvash-Prull was first and foremost a bard and composer. Secondly he was a spellcaster and the two facets came together when he composed his only symphony. Integrated into the symphony are his own researched bardic spells, but they are woven into the music and are far from obvious, even to other spellcasters.
The symphony itself usually appears as a large folio that contains several dozen sheets of music for a full orchestra of instruments. Copies of the symphony typically appear on high-quality sheets of parchment or paper and are beautifully illuminated. The artistic quality of this complete symphony in sheet music form is of such mastery that it is worth 2,500 gp to a collector on the merits of its workmanship alone. To a collector who knows the symphony's secret it is worth considerably more.
One of the little-known facts about this symphony is that several of Tvash-Prull's unique spells are cleverly encoded in the sheet music. Read Magic, deciphers the magic, as does a successful Spellcraft check (DC 22 + spell level), but the spells can not be cast directly from the sheets.
Tvash-Prull's symphony was created with bardic spellcasters in mind, and thus the spells hidden there are only open to them. A bard who successfully studies the symphony's spells may exchange any spells they currently know of an equal level for any of the spells encoded in the sheets. They can also select any of these spells as new spells in the future when they increase their bard spellcaster levels.
