A few months ago, at Manhattan’s Yamaha studios, a large black piano stood onstage—minus any pianist—playing what was billed as a “re-performance” of Glenn Gould’s 1955 mono recording of J.S. Bach’s Goldberg Variations. The feat was accomplished with a MIDI (Musical Instrument Digital Interface) file containing vastly detailed information about Gould’s old record, including such matters as volume and tempo, fed through a Disklavier Pro piano, one of the few concert grands that can play such files.
But why bother? This bestselling record—Gould would rerecord the “Goldbergs” in stereo in 1981—has remained in print ever since it was first published by Sony Classical (now Columbia) in 1956. Why this staged display for a pianist who famously loathed concert performance, retiring at 31 from live recitals to devote himself entirely to recording, films, and radio? The event’s real protagonist, of course, was Zenph Studios, a North Carolina software company, which developed this technology.
Listening to the Zenph re-performance, it is immediately clear that no musician’s fingers are actually hitting keys. The notes may be faithfully replicated in terms of the duration of notes and their intensity, but the physical presence of a pianist is sadly missing. What is a piano without a pianist, except an odd-looking piece of furniture? When Franz Liszt began the tradition of piano recitals in the 19th century, one audience member was heard to ask quizzically, “A piano recital? How can a piano recite?” The question today—thanks to Zenph—becomes “Should a piano recite?”
