Knowing, as we do, Franklin’s versatility, it is nevertheless somewhat of a surprise to find him venturing into the sphere of music. He is said to have been able to play on the harp, the guitar, and the violin, but probably only in a philosopher’s way and not well on any of them. Some people in England had succeeded in constructing a musical instrument made of glasses, the idea being taken from the pleasant sound produced by passing a wet finger round the brim of a drinking-glass. When in England Franklin was so delighted with these instruments that he set about improving them. He had glasses specially moulded of a bell-like shape and ground with great care until each had its proper note. They were placed in a frame in such a way that they could all be set revolving at once by means of a treadle worked by the foot, and as they revolved they were played by the wet fingers pressed on their brims. He gave the name “Armonica” to his instrument, and describes its tones as “incomparably sweet beyond those of any other.” It is said to have been used in public concerts, and it was one of the curiosities at his famous Craven Street lodging-house in London, where he also had a fine electrical apparatus, and took pleasure in showing his English friends the American experiments of which they had heard so much. He seems to have studied music with great care as a science, just as he studied the whirlwinds, the smoke, and the lightning; but he was unalterably opposed to the so-called modern music then becoming fashionable, and which is still to a great extent the music of our time. The pleasure derived from it was, he said, not the natural pleasure caused by harmony of sounds, but rather that felt on seeing the surprising feats of tumblers and rope-dancers. “Many pieces of it are mere compositions of tricks. I have sometimes, at a concert, attended by a common audience, placed myself so as to see all their faces, and observed no signs of pleasure in them during the performance of a great part that was admired by the performers themselves; while a plain old Scotch tune, which they disdained, and could scarcely be prevailed upon to play, gave manifest and general delight.” In a letter to Lord Kames which has been often quoted he explained at length, and for the most part in very technical language, the reasons for the superiority of the Scotch tunes.
