Tesla Tune (2014) is dedicated to the inventor Nikola Tesla. The piece emits sound that comes from an alternating current transformer, which is lead through a programmer (time-adjusted frequency equalizer and switch box) to channel the sound through eight different outputs—pipes. These eight pipes of different lengths hang from a ceiling, producing what seem to be different sounds, but the frequency is always the same, 60 Hz. The lengths of the pipes affect the pitch.

Finnbogi Pétursson, born in Reykjavík, Iceland, has been exhibiting since 1980 and is one of Iceland's most prominent light and sound artists. He is known for works that fuse sound, light, sculpture, architecture, and drawings. Sound—a crucial element—is typically incorporated into spare sculptural installations. Pétursson represented Iceland at the Venice Biennial in 2001 with his monumental sound installation Diabolus. His artworks are held in numerous private collections as well as at the Thyssen-Bornemisza Art Contemporary, Vienna, Austria, and the National Gallery of Iceland, Reykjavík, Iceland. Permanent installations are at Landsvirkjun, Vatnsfellsvirkjun (an electric power plant) Reykjavík University, and the Reykjavík Energy Headquarters. Finnbogi lives and works in Reykjavík, Iceland.
