"For myself, I can only say that I am astonished and somewhat terrified at the results of this evening's experiment — astonished at the wonderful power you have developed, and terrified at the thought that so much hideous and bad music may be put on record forever. But all the same I think it is the most wonderful thing that I have ever experienced, and I congratulate you with all my heart on this wonderful discovery."
— Arthur Sullivan to Edison, 1888
