Kazhinji shandisa K. mutoni a1 (la yekutanga octave). Vaimbi nekwaya. makondukita anoshandisawo K. mutoni c2. Kune zvakare chromatic K., matavi ayo ane huremu hwenhare uye anochinjika neinosiyana frequency zvichienderana nenzvimbo yezviremu. Iyo referensi oscillation frequency a1 panguva yekugadzirwa kwaK muna 1711 Eng. muimbi J. Shore aive 419,9 hertz (839,8 nyore oscillations pasekondi). Zvadaro, zvishoma nezvishoma yakawedzera pakati. 19th century yakasvika kudhipatimendi nyika kusvika 453-456 hertz. In con. Muzana remakore rechi18 pamusana pemunyori uye kondakita J. Sarti, akashanda muSt. Petersburg, "Petersburg tuning fork" ine frequency yea1 = 436 hertz yakaunzwa muRussia. Muna 1858, Paris Academy yeScience yakaronga izvo zvinodaidzwa. zvakajairika K. ine frequency a1 = 435 hertz (kureva, inenge yakafanana neSt. Petersburg). Muna 1885 paIntern. musangano muVienna, iyi frequency yakagamuchirwa seyepasirese. mwero wenzwi uye wakagamuchira zita. mimhanzi kuvaka.
