“A pioneer in video art since the 1960s, Paik believes he may be  particularly suited to this medium by his training in music. “I think I  understand time better than the video artists who came from  painting-sculpture,” says Paik, because “music is the manipulation of  time… . As painters understand abstract space, I understand abstract time“—and  time is integral to video art, which must unfold in a temporal  duration. Paik’s art often uses or refers to music and musical  instruments. Meanwhile he has also built structures out of or  incorporating television sets, so that his video images become elements  in an overall sculptural configuration.
Paik is a veteran of the  Dada-inspired Fluxus group, and his work can be cheerfully anarchic.  This untitled piece, though, is elegiac in tone. An upright player piano  is piled with fifteen televisions. Wired to these sets are small  closed-circuit cameras trained on the instrument’s mechanism, so that as  the piano, unmanned, plays ragtime, its workings appear on the screens.  We also see, on one monitor at the sculpture’s top and on another at  its foot, the image of the late John Cage. A composer and aesthetic  thinker who embraced chance, accident, and a certain playfulness of  approach, Cage was influential for many postwar artists, including Paik.” - MoMA Wall Label
