Kael watched as she carved more holes, but he noticed they weren't all the same size. "Why is that one tiny and the other wide?" I can tell you about the , which lack modern key mechanisms

Instruments are classified by the profile of their internal bore:

A larger hole vents more efficiently, making the "effective length" closer to the hole's physical location. Harder to cover with bare fingers; requires complex

Harder to cover with bare fingers; requires complex mechanical keys.

Strategic hole placement allows for chromatic notes without a key for every half-step. Whether you are a budding instrument maker or

Use acoustic impedance modeling to place holes where fingers or key mechanisms can realistically reach them.

Whether you are a budding instrument maker or a curious musician, here are the fundamental principles governing air columns and toneholes. 1. The Physics of the Air Column

High-frequency waves bypass the open toneholes and travel all the way to the end of the instrument bell.
