Why singers seize up on high notes, and what to do about it. John Henny on fascia, biotensegrity, and imagery that actually connects to function.

Your student knows exactly what to do - and their body locks up anyway. In this IVTOM conference session John Henny explains why: fascia behaves like a non-Newtonian fluid, hardening under sudden force and flowing under slow, sustained pressure. He demonstrates it with oobleck and a gummy worm, then shows how the same principle governs a clenched jaw, a high larynx, and a note you try to "hit." From there he rebuilds imagery as a teaching tool - visual, tactile and metaphor-to-function cues, the pipe organ, the floating parachute, the melting ice cream larynx - and the noticing-assessing-experimenting loop that tells you whether a cue is working. For voice teachers.
