Max Dahlin. To kill the necromancer (№ 170660)

Powers of necromancy, say, like an ear for music. Perhaps.
Some passionately want to be singers and musicians, call the teachers, pay them gold per hour, spend a lot of time and efforts to make the most of the lute or flute in any harmonious sound, to no avail. Torment the ears of others. And their lackey hums, rubbing plates, and passers-by outside the window stopped to listen. A gift from above.
