Tuned Slit Drum Bank Explorer

Blueprint Thesis

Keep all twelve resonator boxes dimensionally identical, then tune the chromatic octave through tongue length and small tip-mass corrections. Prototype C3, F#3, and B3 first so the full bank inherits measured root-stiffness corrections.

C3-B312 chromatic primary tongues.

200 x 100 x 80Millimeter steel boxes.

3 sMinimum sustain after rack mounting.

Packet Files

design.md

Private-review chromatic slit-drum bank: twelve identical folded boxes, tuned by measured tongue length corrections.

bom.csv

Core items: 1.5 mm cold-rolled steel, rack isolation strips, M4 retainers, soft mallets, and temporary tuning masses.

validation.csv

Pass gates: 12 primary pitches within +/-10 cents, sustain at least 3 seconds, adjacent cross-talk below target, and ergonomic chromatic sweep.

tuning-notes.md

Leave tongues long, measure raw pitch, trim in small steps, and avoid root grinding.

risks.md

Main risks: root heat damage, weld warp, model mismatch, secondary tongue cross-talk, and rack damping.
