when the hammer strike the string,the string tension will be increased. as a result, the frequencies of all of the partials will be raised at different level,depends on how the pianist play and how the hammer/string is. General speaking,a heavy hammer can raise the lower partial frequencies more and raise the higher partials frequencies less. When we check the inharmonicity,any tuning machine simply assume that the first partial(fundamental)has none inharmonicity.in the real world,any partial,including the fundamental, has imharmoniucity.in other words,the tuning machine check the "relitive inharmonicity",not the real one.
