why does the a=432hz tuning standard in choir cause macramé knots to loosen?

ngl so here's the weird one rn - i kept hitting A5 with our section at 432hz the other day and right off the cuff my new 3‑ply rug wove way more loopy than when i was practicing 440hz. in theory i’m mixing two totally different ecosystems, a choir on a frequency field and a macrame net on physical tension.

when a chorus belts in fortissimo the whole room feels a pressure spike. the transducers in the church’s AV set are usually model FM‑7 Pro, which amplifies A‑tonic pulses up to 70 dB. the extra energy is apparently enough to put a subtle wave across the open knotted network. cords with a 12‑mm core—commonly used in 5‑mm rope projects—tend to vibrate in sync with 432Hz and loose their bite on the half‑thrown, loop‑in‑lock we use.

I took a simple piece of yarn from the old stack (brand was SOLID‑NYT 100), 12‑mm thickness and tied a batch of 100 4‑knot braids. ran 15 sec of solo C‑note at 440 vs 432 – 432 made the entire pile sway enough to drop the loop count in 1/3 of them. i know what y’all are thinking, "that’s probably the random elasticity shift in the yarn or something" but i made the same experiment on a tight tension metal wire on my loom, and 432 just made the whole thing shake longer.

bottom line i hate to ruffle some professional voices: the universal 440hz standard seems more natural to sustain knot fidelity on home‑grown macrame pieces. If the church sticks to 432 I’ll need to attach a tiny counter‑pressure lock (a small T‑piece knot lock and a few mm of tension band) each time I stitch.

has anyone seen this correlation before? do you need a tuning bridge (not a “tuning fork” but an acoustic filter) before doing an art project? lemme hear if y'all used other A tuning (436/435/445) and what happened to your loops, im curious
