Definition from Wiktionary, the free dictionary
tightwire (plural tightwires)
- A tightrope.
1988 April 8, Cerinda Survant, “The Man Who Made History Dance”, Chicago Reader:
- The Chinese Conjurer's dramatic jumps, flexed wrists, and endless fingers are fascinating; the Acrobats, whose dance suggests tumbling, juggling, and walking on the tightwire, display a breathtaking virtuosity; the Little American Girl's pyrotechnical performance is pretty and pert; and the two men in a horse suit almost inevitably reduce the audience to helpless laughter.
