2) Umthombo womsindo, ogobile futhi omisiwe phakathi kwensimbi. induku lapho iziphetho zayo zikhululekile ukugoqa. Isebenza njengendinganiso yephimbo lapho usetha umculo. izinsimbi kanye nokucula. Ngokuvamile sebenzisa u-K. ngethoni u-a1 (la we-octave yokuqala). Abaculi namakhwaya. abaqhubi baphinde basebenzisa u-K. ngephimbo c2. Kukhona futhi i-chromatic K., amagatsha afakelwe izisindo zeselula futhi aguquguquka nefrikhwensi eguquguqukayo kuye ngendawo yezisindo. Ireferensi ye-oscillation frequency a1 ngesikhathi sokusungulwa kuka-K ngo-1711 Eng. umculi u-J. Shore wayengu-419,9 hertz (839,8 oscillations elula ngomzuzwana). Kamuva, kancane kancane anda phakathi. Ikhulu le-19 lafinyelela emazweni omnyango kuze kufike ku-453-456 hertz. Ngokuvumelana. Ikhulu le-18 ngesinyathelo somqambi nombhidisi u-J. Sarti, owayesebenza e-St. Petersburg, "i-Petersburg tuning fork" ene-frequency ye-a1 = 436 hertz yethulwa eRussia. Ngo-1858, i-Paris Academy of Sciences yahlongoza lokho okubizwa ngokuthi. evamile K. ene-frequency a1 = 435 hertz (okungukuthi, ecishe ifane neSt. Petersburg). Ngo-1885 ku-Intern. engqungqutheleni e-Vienna, le mvamisa yamukelwa njengeyamazwe ngamazwe. izinga lephimbo futhi wathola igama. isakhiwo somculo. E-Russia, kusukela ngo-1 Jan. 1936 kukhona indinganiso ene-frequency a1 = 440 hertz.
