Glockenspiel Build Packet

A C5-C7 chromatic metal-bar idiophone packet with a 10-bar pentatonic variant, free-free beam math, node-support gates, metallurgy checks, and tuning validation paths. Current readiness is a V5 build-packet candidate, not a measured or build-ready release.

Status

Primary target
25 bars C5-C7Chromatic 6061-T6 aluminum flat-bar glockenspiel.
Variant
10 bars pentatonicC-major art-fair build using the same stock and support logic.
Readiness
V5 candidateNo bars cut, mounted, struck, measured, or tuned yet.
Authority
Design-table firstMeasured K, node-support sustain, and framed tuning remain blockers.
Release boundary: use this packet for design review and pilot planning. Do not treat the bar lengths, node supports, metallurgy constants, SVGs, PDF, site, or Wolfram source as build-verified until the validation rows carry measured evidence.
