A ney is a matter of measurement more than craftsmanship. The same reed can yield different tunings; hole placement and bore size decide.
1. Selecting and cutting
The cane must be straight, with even nodes and a diameter close to target. After cutting it cures for months; cracked or warped reeds are discarded.
2. Measuring nodes
Tuning depends on where holes fall relative to nodes.
3. Drilling
Six front holes and one back hole, widened while checking pitch. Irreversible.
4. Tuning
Tested at 440 Hz concert pitch; if it will not hold tuning, it is not sold.
5. Headpiece and finish
Buffalo horn, wood or delrin; the joint is machined precisely.
6. Final check
Last play test for sound, tuning and body integrity.
