Inspired by her outdoor installation Pink Rayon (1955), Tanaka created Bell in 1955.Kato, Mizuho. "Atsuko Tanaka's 'Paintings', as Seen Through Work (Bell)." In Tanaka Atsuko: The Art of Connecting, edited by Jonathan Watkins and Mizuho Kato, 39-47. Birmingham: Ikon Gallery, 2011. It consisted of a string of twenty electric bells and a button with the sign "Please feel free to push the button, Atsuko Tanaka". In early versions of Bell, the bells were laid at two-meter intervals with each other to surround a gallery room. Once visitors pressed the button, it would make the bells ring in sequence for two minutes. The arrangement of the bells was adapted to different spaces at later exhibitions.
