Overtone Throat

Sing one steady note and play its hidden overtone ladder: the throat listens to your timbre, then a drone bank blooms and sustains the partials you emphasize — a bright cursor walking up the harmonics like a Tuvan throat singer.

Each row is one overtone; density = its live energy, scrolling right to left like an oscilloscope. Hold a vowel and slowly brighten it — the ► emerald cursor marks the partial you are shaping toward, and it sustains after your voice softens.
