Full length and harmonic = length reeds are a balance between the reed oscillation frequency and the = resonator oscillation frequency. When regulating such a pipe you use the reed and resonator adjustments to get the loudness and desired timbre when you are terracing and regulating. Quality reeds are almost always correctly on frequency at the wire. The temperature change in an organ that causes = tuning drift effects the air enclosed in the resonator much more so you tune the resonator first. Only when the reed is off do you start with the wire. Shading the pipe and other tricks determine this.   Al Sefl
