Isikali semvelo |
Isilinganiso semvelo se-harmonic siwuchungechunge lwamathoni ayingxenye ahlelwe ngokulandelana okukhuphukayo, okungukuthi, okuyinhloko. amathoni namathoni, amathoni osn. amathoni avela eqinisweni lokuthi umzimba ozwakalayo (intambo, ikholomu yomoya, njll.) awuguquguquki nje kuphela, kodwa futhi izingxenye (1/3, 1/3, 1/4, njll.) . Ama-Overtones awathathwa njengazimele. imisindo; zizwakala eyodwa ne-main. iphimbo, futhi kuye ngohlobo lomthombo womsindo nesikhala sensimbi, ukugqama kwamathoni athile athile kunquma umbala ne-timbre yomsindo. Isilinganiso semvamisa ye-oscillation yamathoni ayingxenye N. h. kuvezwe uchungechunge lwezinombolo zemvelo; ukuze lezi zinombolo zihambisane nenombolo ye-ordinal yama-overtones, okuyinhloko. ithoni N. h. ngokuvamile kubhekwa njengento yokuqala:
Amathoni ayingxenye, avalelwe kubakaki esibonelweni, ngaphakathi kwendawo yawo ahluka ngandlela-thile kufrikhwensi yokudlidliza kusukela kumisindo efanayo yesistimu epholile; imisindo emakwe ngokuthi minus iphansi, futhi ngokuhlanganisa iphakeme kunemisindo ehambisanayo yesikali somoya. Amathoni ayisithupha aphansi N. h. ziyingxenye ye-triad enkulu, enquma i-acoustic yayo. ungwaqa. Lokhu kukhombisa ukuthi imithetho yokuhlanganiswa kwemisindo evumelanayo ihambisana nemvelo yokwakheka komsindo; isebenza njengesisekelo esingokomzimba sawo wonke umculo. izinhlelo.
Izinsimbi zomoya, ngosizo lokuphefumula, ezifinyelelwa ngokushintsha ukungezwani kwemisipha ye-labial namandla okuphefumula komoya, ngaphandle kokusebenzisa ama-valve namanye amadivaysi ashintsha ubude bekholomu yomoya, enze kube nokwenzeka ukukhipha imisindo yangempela, okuthi ngokuhlangene kwakheke ukufana kokuphelele noma okungaphelele (kuye ngobukhulu nokwakheka kwensimbi) AD - inombolo yemisindo yazo yemvelo.
