The Wind Pipes are a simple soundequipment which enables the person„playing them“ to experience physicallythe relation of cause and effect. Thethree, ground level integrated see-sawbeams can be moved independently fromeach other. Due to the movement of thebeams, the air pressure which is requiredfor playing the pipes is produced. Bymeans of shifting the weight or movingfrom one beam to the other, differentsimple sequences of notes are produced.Six different notes are possible. Childrenenjoy very much making „music“ withthe whole body or producing „beautiful“(dreadful) sequences of notes by usingthe see-saw effect of the beams.
