I have found the inharmonicity is to found in all stringed instruments, harps, fortepiano, pianos, harsichords and others. The inharmonicty goes down with tension and wire sizes such that a low tension instrument with fine wires will have least inharmoncity. I have found that two cents is about right for a harpsichord.
