On another occasion I brought him [Ignace Mascheles], for his criticism, a pianoforte composition of my own of which he had accepted the dedication. After he had made a slight change or two I asked him if I now should play to him the corrected version. "My dear sir," he said with a smile, "there's no need of that, I hear it all in my mind's ear-- I really must tell you a little story about that. When I wrote my concerto with three kettle-drums"-- he seemed to feel a particular pride and satisfaction in remembering this then almost unheard-of boldness and revolutionary innovation-- "when I wrote my concerto with three kettle-drums, I came to a 'tutti' which I wanted rather fully and noisily orchestrated. Well-- will you believe, I heard that tutti and the noise of the different instruments so distinctly whilst I was writing it, that-- that I got a headache!".
