I-Metronome |

kusukela ku-Greek metron - isilinganiso kanye nomos - umthetho

Idivayisi yokunquma izinga lokushisa lomculo odlalwayo. umkhiqizo. ngokubala ngokunembile ubude bemitha. I-M. iqukethe iwashi lasentwasahlobo elakhelwe ikesi elimise okwephiramidi, i-pendulum enosinki ogudlukayo, kanye nesikali esinezihlukaniso esibonisa inani lama-oscillation enziwa i-pendulum ngomzuzu. I-pendulum enyakazayo ikhiqiza imisindo ecacile, enyakazayo. Ukushwibeka okushesha kakhulu kwenzeka lapho isisindo singezansi, eduze kwe-axis ye-pendulum; njengoba isisindo siqhubekela ekupheleni kwamahhala, ukunyakaza kunciphisa. I-Metronomic igama letempo lihlanganisa ubude besikhathi senothi, esithathwa njengokuyinhloko. isabelo semethrikhi, uphawu olulinganayo nenombolo ebonisa inombolo edingekayo yemethrikhi. ukwabelana ngomzuzu. Ngokwesibonelo, = 60 igolide = 80. Esimweni sokuqala, isisindo sisethwe cishe. ukuhlukana ngenombolo 60 kanye nemisindo ye-metronome ihambisana namanothi ayingxenye, okwesibili - mayelana nesigaba 80, amanothi ekota ahambisana nemisindo ye-metronome. Izimpawu zika-M. zinamandla. ukubaluleka kwemfundo nokuqeqeshwa; abaculi-abadlali M. isetshenziswa kuphela ekuqaleni komsebenzi emsebenzini.

Imishini yohlobo lwe-M yavela ekupheleni kwekhulu le-17. Okuphumelele kakhulu kulawa kwaba nguM. wohlelo lwe-IN Meltsel (olugunyazwe ngo-1816), olusasetshenziswa nanamuhla (esikhathini esedlule, lapho kuqokwa u-M., izinhlamvu ezithi MM – metronome kaMelzel) zabekwa ngaphambili. kwamanothi.
