… At the other end of the scale of control was the concluding work of Frederick Lesemann, The Knight's Tour, in which no pitches at all are notated, but only configurations of lines or sound-types or treatments. As the title suggests, the score is analogous to squares on a chess board, different boxes indicating treatments and combinations, worked out by three performers who improvise and cue each other. With so little control by the composer, the effect of Knight's Tour depends heavily upon the performers. This version was exciting and occasionally ear-splitting.
