The txalaparta (zaldi-parta / horse-walking sound) reflects the resounding, irregular but balanced, haughty and nimble movement of a horse. It is also an eminently Basque percussion instrument, a primary musical object, played by two musicians, like the two legs of a same person, a living being that moves, walks and runs, four wooden makilas or sticks of wood sharing a magical and evocative trot awakening the most liberal and wildest of intimate and collective emotions.
