The performance Tone-line revolves around items of clothing hanging on a clothesline; outer garments such as sweaters, blouses and dresses. Time and again, Knowles purposefully takes up position behind a different garment, puts her arms into the sleeves and produces a tone. In her act, she not only turns the clothesline into a musical scale, but also, constantly seems to put herself into ‘someone else’s’ place for a moment, so that each tone not only expresses its position on the scale, but also her changing position with regard to the audience. With great precision, she chooses her route through the clothes. Her almost regal treatment of everyday objects lends a ceremonial character to the performance.
