"The Music of Erich Zann" is a short story by American author H. P. Lovecraft. Written in December 1921, it was first published in National Amateur, March 1922. A university student is forced, by his lack of funds, to take the only lodging he can afford. In a strange part of the city he had never seen before, on a street named "Rue d'Auseil", he finds an apartment in an almost empty building. One of the few other tenants is an old German man named Erich Zann.
The old man is mute and plays the viol with a local orchestra. He lives on the top floor and when alone at night, plays strange melodies never heard before.
