150+ Native American style wooden flutes built between roughly 2018 and 2021, plus the parametric design table covering G3 to A4 and the build registry tracking each flute's wood species, key, dimensions, and build outcomes. Methodology learned from Blue Bear Flutes.

Stave-built didgeridoo design — 2013 acoustic study covering 25 musical keys (C1-C3, with build lengths from ~27" at C3 to ~107" at C1), frequency-to-length calculations, stave geometry across L:D aspect ratios 22:1 to 26:1, and design brainstorming for internal-rib patterns. Sister project to djembe and ashiko-drum-workshop.
