About this model

Helmonica — a chorused vessel-flute you play like a harmonica One supportless print. No hardware. Pitch set by geometry. Every parameter in an OpenSCAD customizer. Slide your lips along the front and you get a pentatonic row where every neighbour is a fourth or a fifth, every note shimmers like a musette accordion, and a drone sits under it all. There is no fingering and no wrong note. Hand it to someone who has never played anything and they will be making music in ten seconds. How it works Each note is a Helmholtz resonator (the physics of blowing across a bottle) with its own recorder-style fipple. Pitch depends only on the chamber volume and the window, so the generator solves the chamber depth from the target frequency: `` f = (c / 2π) · √( A_window / (L_eff · V) ) ` Every note is act…
