Designing wind instruments is a balance between acoustic physics, ergonomics, manufacturing constraints, and artistic goals. Mastery requires combining analytical models (lumped-element, transmission-line), numerical simulation (FEM/BEM), empirical measurement (input impedance), and iterative craftsmanship (voicing and pad adjustment). Toneholes are central control points: their placement, size, and geometry mediate the effective acoustic length, influence timbre and tuning, and interact with bore shape and excitation to produce the instrument’s characteristic voice. numerical simulation (FEM/BEM)
