Chipangizo chodziwira tempo ya nyimbo yomwe ikuimbidwa. prod. powerengera molondola kutalika kwa mita. M. imakhala ndi makina a mawotchi a masika omwe amapangidwa ndi piramidi yooneka ngati piramidi, pendulum yokhala ndi sinki yosunthika, ndi sikelo yokhala ndi magawo omwe amasonyeza kuchuluka kwa ma oscillations opangidwa ndi pendulum pamphindi. Pendulum yogwedezeka imatulutsa mawu omveka bwino, omveka. Kuthamanga kwachangu kumachitika pamene kulemera kuli pansi, pafupi ndi olamulira a pendulum; pamene kulemera kumapita kumapeto kwaufulu, kuyenda kumachepa. Metronomic kutchulidwa kwa tempo kumakhala ndi nthawi yolemba, yomwe imatengedwa ngati yayikulu. metric share, chizindikiro chofanana ndi nambala yosonyeza nambala yofunikira ya metric. gawani pa mphindi imodzi. Mwachitsanzo, = 60 golidi = 80. Poyamba, kulemera kumayikidwa pafupifupi. magawo omwe ali ndi nambala 60 ndi mawu a metronome amafanana ndi theka la manotsi, chachiwiri - pafupifupi magawano 80, zolemba za kotala zimagwirizana ndi phokoso la metronome. Zizindikiro za M. zili ndi mphamvu. mtengo wamaphunziro ndi maphunziro; oimba-oyimba M. amagwiritsidwa ntchito atangoyamba kumene ntchito.

Zida za mtundu wa M zidawonekera kumapeto kwa zaka za zana la 17. Opambana kwambiri mwa awa adakhala M. ya dongosolo la IN Meltsel (lovomerezeka mu 1816), lomwe likugwiritsidwabe ntchito masiku ano (kale, popanga M., zilembo MM - metronome ya Melzel) zidayikidwa patsogolo. za zolemba.
