What I did succeed in doing was to overhear the nocturnal playing of the dumb old man. At first I would tip-toe up to my old fifth floor, then I grew bold enough to climb the last creaking staircase to the peaked garret. There in the narrow hall, outside the bolted door with the covered keyhole, I often heard sounds which filled me with an indefinable dread—the dread of vague wonder and brooding mystery. It was not that the sounds were hideous, for they were not; but that they held vibrations suggesting nothing on this globe of earth, and that at certain intervals they assumed a symphonic quality which I could hardly conceive as produced by one player. Certainly, Erich Zann was a genius of wild power. As the weeks passed, the playing grew wilder, whilst the old musician acquired an increasing haggardness and furtiveness pitiful to behold. He now refused to admit me at any time, and shunned me whenever we met on the stairs.
Then one night as I listened at the door, I heard the shrieking viol swell into a chaotic babel of sound; a pandemonium which would have led me to doubt my own shaking sanity had there not come from behind that barred portal a piteous proof that the horror was real—the awful, inarticulate cry which only a mute can utter, and which rises only in moments of the most terrible fear or anguish. I knocked repeatedly at the door, but received no response. Afterward I waited in the black hallway, shivering with cold and fear, till I heard the poor musician’s feeble effort to rise from the floor by the aid of a chair. Believing him just conscious after a fainting fit, I renewed my rapping, at the same time calling out my name reassuringly. I heard Zann stumble to the window and close both shutter and sash, then stumble to the door, which he falteringly unfastened to admit me. This time his delight at having me present was real; for his distorted face gleamed with relief while he clutched at my coat as a child clutches at its mother’s skirts.
Shaking pathetically, the old man forced me into a chair whilst he sank into another, beside which his viol and bow lay carelessly on the floor. He sat for some time inactive, nodding oddly, but having a paradoxical suggestion of intense and frightened listening. Subsequently he seemed to be satisfied, and crossing to a chair by the table wrote a brief note, handed it to me, and returned to the table, where he began to write rapidly and incessantly. The note implored me in the name of mercy, and for the sake of my own curiosity, to wait where I was while he prepared a full account in German of all the marvels and terrors which beset him. I waited, and the dumb man’s pencil flew.
It was perhaps an hour later, while I still waited and while the old musician’s feverishly written sheets still continued to pile up, that I saw Zann start as from the hint of a horrible shock. Unmistakably he was looking at the curtained window and listening shudderingly. Then I half fancied I heard a sound myself; though it was not a horrible sound, but rather an exquisitely low and infinitely distant musical note, suggesting a player in one of the neighboring houses, or in some abode beyond the lofty wall over which I had never been able to look. Upon Zann the effect was terrible, for, dropping his pencil, suddenly he rose, seized his viol, and commenced to rend the night with the wildest playing I had ever heard from his bow save when listening at the barred door.
