), giving the instrument its characteristic hollow, woody sound and causing it to overblow at the twelfth rather than the octave.

): Larger holes let more air escape, making the reflection cleaner and closer to the physical location of the hole. Smaller holes restrict air movement, forcing the acoustic wave to "peak" further down the tube. Tonehole Height/Chimney Depth ( ), giving the instrument its characteristic hollow, woody

An instrument plays most easily at frequencies where its acoustic impedance peaks. At these frequencies, minimal effort from the player yields maximum acoustic pressure inside the bore. Tonehole Height/Chimney Depth ( An instrument plays most

No wind instrument is perfect. Designers must balance: giving the instrument its characteristic hollow

The internal diameter expands continuously from the mouthpiece to the bell (e.g., oboes, saxophones, bassoons). Boundary Conditions and Acoustic Behavior

Toneholes allow a musician to change the length of the air column without physically cutting the pipe.
