Horn (cantrip)

Horn was a haunting cantrip that neophyte wizards could learn. It simulated the sound of a single note from a horn with some control over volume, apparent distance, and steadiness.

Effects
This cantrip produced a single horn-like note that could be clearly heard from to  away, depending on the volume chosen by the caster. The amount of echo and the perceived distance could also be chosen, and the note could be made to waver with tremolo. With practice, a wizard could imitate a horn well enough that it was indistinguishable from the real thing. The duration of the note was determined by how long the caster held their mouth in the correct shape.

Components
This cantrip required verbal and somatic components to cast. The caster first softly hummed a note to pick the pitch of the horn sound. The horn sounded when the caster opened their mouth in an O-shape and curled the fingers of one hand around their mouth. The volume was varied by opening or closing the gap formed by the circle of fingers and tremolo could be added by shaking the fingers.

History
This cantrip was one of three unique cantrips recorded in Glanvyl's Workbook, penned by the relatively unknown Glanvyl of Scornubel in the 11 century DR.
