A twisting frame 1, and a method of twisting yarn 11 in which a twist is applied to the yarn by signals having a 1/f fluctuation to yield a yarn 11 in which the yarn count varies with a 1/f fluctuation. The first aspect is a twisting method that applies twist to a single yarn or a plural number of yarns, in which a twist is applied to the yarn or yarns by setting the twist count to correspond to the strengths of serial signals having a 1/f fluctuation.

A spinning method and a spinning frame are provided that yields spun yarn, with the comfortable feel of a hand-spun yarn, on an industrial scale. In spinning frame 1, rovings 11 are drafted with signals derived from a numerical sequence of having a 1/f fluctuation or signals derived from a melody or other sound having a 1/f fluctuation to yield a spun yarn 13 in which the diameter varies with said 1/f fluctuation, thus providing a natural, comfortable feel.
