How do woodwind instruments change pitch?

In woodwind instruments, the effective length is changed by opening and closing finger- holes or keyholes along the side. This is the way pitch is changed within the same register of the instrument: all holes closed gives the lowest note, and opening the holes successively from the bottom end gives a chromatic scale.
