: Explains the behavior of air as it reflects and interferes within different enclosures to create resonance. Tonehole Theory Sizing and Placement

Thicker instrument walls create deep chimneys, which add acoustic mass and lower the pitch.

are equally important. Undercutting reduces kinetic energy losses caused by discontinuities around the hole, lowers local non‑linear flow phenomena (such as boundary layer separation, jet formation, and vortices), and reduces harmonic distortion in the radiated signal. The result is a cleaner, more stable sound across the instrument's dynamic range. This link or copies made by others cannot be deleted

Instruments are classified by the profile of their internal bore:

Open at both ends. They produce both even and odd harmonics (1f, 2f, 3f, 4f...), resulting in a bright, pure sound. They change pitch by an octave when overblown.

Designing a wind instrument requires balancing three main factors: hole size, hole placement, and tonehole chimney height. Changing any one of these features changes how the entire instrument behaves. Large vs. Small Toneholes
