In 1927 the Dutch architect J. J. P. Oud designed as a wedding gift for a friend a piano lamp that was subsequently put into production and given the name "Giso 404." Oud, together with Gerrit Rietveld and Theo van Doesburg, was a prominent member of the avant-garde De Stijl movement; here, he has abandoned any suggestion of conventional design. His lamp, intended to sit on top of an upright piano, is boldly cantilevered beyond the edge in order to illuminate the keyboard and sheet music below. The weight of the cylinder floating in space, which houses the long lightbulb, is dynamically balanced by a solid metal sphere. Effectively an abstract sculpture, the lamp strongly suggests, in its geometric form, the influence of the Bauhaus, to which Oud had close ties.
