Ear Syrinxing Stephen Chase

Affix at least three poster tubes of differing lengths in a row where all tubes are level at one end , thus resembling a set of panpipes

Invite others to use instrument with the following text attached to the instrument or placed nearby*:

Pick up tubes slowly raise to ear listen at the end of one tube after a while listen at the end of the neighbouring tube after a while listen at the end of the remaining tube compare and contrast sounds heard through the different tubes

*Optional: feed a low to medium volume soundtrack of white or brown noise into the room to assist perception of the different resonant pitches of the tubes
