No likeness of the virtuoso has survived, but contemporaries describe a tall man of good figure with black, penetrating eyes, a severe, handsome face, and a prominent though elegantly shaped nose. That he was a Jew was widely accepted, and loudly published by his rivals; there is no evidence that Visser bothered to deny the consensus. His hands, of course, were his most distinguishing feature. The first edition of Groves Dictionary states that Visser had the hands of a natural pianist: broad, elastic palms, spatulate fingers, and exceptionally long little fingers. He could stretch a twelfth and play left-hand chords such as A-flat, E-flat, and A-flat and C, but it was the hypnotically abnormal right hand that ultimately set him apart. “The two ring fingers of his right hand,” the critic Blundren wrote, “are perfect twins, each so exact a mirror image of the other as to give the effect of an optical illusion, and in action possessed of a disturbing crablike agility. Difficult it is, indeed, to repress a shudder when presented with Visser s singular hand.”
Difficult, indeed, and as is so often the case with deformity, a sight that both compelled and repelled. Visser seems not to have emphasized his singular hand during the early stages of his career, but the speed with which he played, to such cataclysmic effect, in time gave rise to unsettling stories. It was his peculiar gift to establish the melody of a piece with his thumbs in the middle register of the piano, then surround the melody with arpeggios, tremolos, double notes, and other devices, moving up and down the keyboard with such insane rapidity that it seemed as if four hands rather than two were at work. His sound was so uncanny that a certain kind of story-tentative, half-jesting at first-began to shadow the pianist: Satan himself was playing with Visser, some said, while others ventured that he’d sold the devil his soul in exchange for the extra finger, which enabled him to play with such hectoring speed.
That Visser had emerged from the mysterium of backward Eastern Europe gave the stories an aura of plausibility. “There is something dark, elusive, and unhealthy in Visser,” remarked Field, while Moscheles said that his rivals playing “does not encourage respectable thoughts.” His few surviving compositions show a troublingly oblique harmonic stance, a cracked Pandora's box of dissonance and atonal sparks, along with the mournful echoes of gypsy songs and the derailed melodies of Galician folk tunes. He became known as the Bohemian Faust, and was much in demand; neither the sinister flavor of his stage persona nor his string of love affairs seemed to diminish his welcome in fashionable salons.
In 1829, however, there was a break. Some say it was due to an incident at the Comte de Gobet’s, where Visser was accused of cheating at cards; his legendary success and extra finger had long made him an object of suspicion, though others said that he was discovered making free with the fifteen-year-old daughter of a baron. Visser was, whatever the cause, refused by society, forced out into le grand public to make his living, this at a time when there were few adequate venues for touring virtuosos and concert managers tended to have the scruples of slave traders. Visser billed himself as the Man with Eleven Fingers, the freak-show aspect of virtuosity made explicit for once, and over the next two years of playing in rowdy beer gardens and firetrap opera houses he perfected his florid stagecraft: the regal entrance, the lavender gloves portentously removed, then the excruciating pause before his hands fell on the keyboard like an avalanche. It was early noted that his audiences were disproportionately female; more remarkable was the delirium that his performances induced, a feature that grew even more pronounced with the addition of the Fantaisie pour Onze Doigts to his repertoire. Hummel, who heard it played in a ballroom in Stuttgart, called it “a most strange and affecting piece, with glints of dissonance issuing from the right hand like the whip of a lash, or very keen razor cuts.” Kalkenbrenner, who happened on it at a brewery in Mainz, compared the chill of the strained harmonies of the loaded right hand to “a trickle of ice-cold water running down one's back,” and added: “I believe that Visser has captured the very sound of Limbo.”
The effect on audiences was astonishing. From the first reported performance, in October 1831, there were accounts of seizures, faintings, and fits of epilepsy among the spectators; though some accused Visser of paying actors to mimic and encourage such convulsions, the phenomenon appears to have been accepted as genuine. Mass motor hysteria would most likely be the diagnosis today, though a physician from Gossl who witnessed one performance proposed theories having to do with electrical contagion; others linked the Fantasy to the Sistine Chapel Syndrome, the hysterics to which certain foreign women-English spinsters, chiefly- sometimes fell prey while viewing the artistic treasures of Italy. In any event, the Fantasy was a short-lived sensation. From its debut in the fall of 1831 until his death the following January, Visser performed the piece perhaps thirty times. He was said to be traveling to Paris to play for the Princess Tversky's salon-the fame of the Fantasy had, conveniently, paroled his reputation-when he was killed stupidly, needlessly, in a tavern in Cologne, knifed in a dispute over cards, so the story goes.
People naturally believed that the Fantasy died with him; even the stupendously gifted Liszt refused to attempt it, rather defensively dismissing the piece as “a waste of time, an oddity based on an alien formation of the hand.” One might study the score as scholars study the texts of a dead language, but the living sound was thought to be lost forever, until that day in 1891 when Leo and Hermine Kuhl brought their six-year-old daughter to the Vienna studio of Herr Moritz Puchel. Herr Puchel listened to the girl play Chopin's “Aeolian Harp” étude; he gave her a portion of Beethoven's A-flat Sonata to sight-read, which she did without stress; he confirmed, as her current teacher, Frau Holzer, had told him, that the child did indeed have perfect pitch. Finally he asked Anna Kuhl to stand before him and place her hands on his upturned palms.
“Yes,” he said gravely, much in the manner of a doctor giving an unhappy diagnosis, “someday she will play Visser's Fantasy.”
Herr Puchel himself had been a prodigy, a student of Czerny’s, who in turn had been a student of Beethoven’s; though he was an undeniably brilliant musician, Puchel's own career as a virtuoso had been thwarted by the misfortune of thin, bony hands. He had, instead, made his reputation as a teacher, and by the age of sixty had achieved such a degree of eminence that he accepted only those students who could answer in the affirmative the following three questions:
