This is the single most important concept in tonehole design. The is the upper limit above which open toneholes no longer behave like simple length-shorteners; instead, they become inefficient radiators.
The design of wind instruments is a constantly evolving field, with new materials and technologies being developed to improve instrument performance and playability. Some potential future directions for wind instrument design include: This is the single most important concept in tonehole design
: Acts as a pipe open at both ends (flute) or closed at one end (clarinet). This is the single most important concept in tonehole design
