The Tate Modern yesterday launched its fifth commissioned installation in the Turbine Hall.

Part of the annual Unilever series within the Turbine Hall, the new installation is sound-based and called Raw Materials.

The exhibition combines 21 audio tracks with the hall’s vast space and illustrates how language, via speech, inhabits the world and how the spoken word reveals moving insights into the human condition.

The installation is organised so that visitors encounter bands of sound that run across the width of the entire hall.

On their way through the exhibition, visitors will encounter an array of different forms of human speech – from jokes and poems to instructions – which are either sung, whispered, chanted or growled.

Created by US-born Bruce Nauman, Raw Materials will remain at the Turbine Hall until 28 March.
