Although organ pipes are very sensitive to minute variations, that does not mean they have inharmonicity. In a piano string, the partials have the freedom to ring at their own independent pitches because after the initial impulse from the hammer, they have no connection with each other. No so with an organ pipe. In place of an initial impulse you have a continuing series of impluses formed by the oscillations at the fundamental frequency. This forces the harmonics to remain locked to the fundamental, hence no inharmonicity. Bob Scott Ann Arbor, Michigan
