When used to play even a single note (a standard action), this musical instrument imprints the rest of an alien melody on the mind of all listeners. Once heard, the melody makes it difficult to concentrate for the rest of the duration (1d6 rounds). No save is allowed against this effect. Listeners suffer a -4 penalty on concentration checks and skill checks and must attempt concentration checks to cast spells (DC 15 + spell level).
