"…the concert began. I heard it through the door - some serenade - at first only vaguely…but presently the sound insisted - a solemn Adagio in E flat. It started simply enough: just a pulse in the lowest registers - bassoons and basset horns - like a rusty squeezebox. It would have been comic except for the slowness, which gave it instead a sort of serenity. And then suddenly, high above it, sounded a single note on the oboe. It hung there unwavering, piercing me through, till breath could hold it no longer, and a clarinet withdrew it out of me, and sweetened it into a phrase of such delight it had me trembling. The light flickered in the room. My eyes clouded! The squeezebox groaned louder, and over it the higher instruments wailed and warbled, throwing lines of sound around me - long lines of pain around and through me. Ah, the pain! Pain as I had never known it. I called up my sharp old God, ‘What is this?…What?!' But the squeezebox went on and on, and the pain cut deeper into my shaking head, until suddenly I was running, dashing through the side door, stumbling downstairs into the street, into the cold night, gasping for life.”
Maybe the characterization of Salieri in Amadeus is not entirely inaccurate? The above is an account by Salieri upon hearing Mozart’s Serenade for Winds in B flat major, K. 361.
