Zvemukati
Kuti ruzha runonzwisiswa se zvakakomba kanaacute zvinoenderana nehuwandu hwekudengenyeka kwaunoita pachikamu chenguva. Iyo inowanzoitika kudedera (yakakwira frequency), iyo inowedzera ruzha. Kana kudengenyeka kusingawanzoitika (low frequency) kurira kwacho kunenge kwakanyanya.
Ruzha rwakaderera kana rwakakwira zvichienderana nekuwanda kwaro. Kuwanda kwenzwi kunoyerwa muHertz (Hz) inova nhamba yemafungu ekuzunguzirwa pasekondi.
Mheremhere inogona kucherechedzwa nenzeve yemunhu iri pakati pe20 Hz kusvika 20 000 Hz. Iyi amplitude inonzi "inonzwika spectrum".
Nekudaro, nenzira yehunyanzvi, mhere yakawanikwa isinganzwiki kuvanhu asi iyo mhuka dzakasiyana dzinoona kana kuburitsa senzira yekutaurirana. Semuenzaniso, mhando dzakasiyana dzehove dzinoburitsa uye dzinoona dzakadzika kwazvo (ine frequency ye10 Hz) uye yakanyanya kukwirira (ine frequency ye325 kHz kana 325,000 Hz) mhere. Izvi zvinoreva kuti mamwe marudzi ehove anotaurirana nemanzwi ari pasi pechiratidziro chinonzwika kuvanhu, nepo vamwe vachidaro nemanzwi ari pamusoro patinogona kunzwa.
- Tatu. Mhere-mhere yakakwira inowanzoonekwa seiya inodarika 5 kHz, inoenzana ne5,000 Hz.
- Makuva. Bass ruzha runowanzo fungidzirwa idzo dziri pazasi pe250 Hz.
- Zvepakati.Iyo iri pakati pe250 Hz ne5,000 Hz inoenderana nenzwi repakati.
Iyo frequency yezwi haifanire kuvhiringidzwa nevhoriyamu. Ruzha rwakakwira-runogona kuve rwakakwira-simba (yakakwira vhoriyamu) kana yakaderera-simba (yakaderera vhoriyamu) isingakanganise kuwanda kwemafungu.
Vhoriyamu inotsanangurwa sehuwandu hwesimba hunopfuura nepasi pechipiri.
Nziyo dzekuMadokero dzinoshandisa manotsi akarongedzwa kuita "octave" zvichibva pawo wave frequency. Kubva pakadzika kusvika kumusoro, zvinyorwa zve octave yega yega zvakarongedzwa seizvi: Ita, re, mi, fa, sol, la, si.
Onawo:
- Mheremhere yakasimba uye isina kusimba
- Natural uye zvekunyepedzera manzwi
Mienzaniso yebass kurira
- Kutinhira. Kutinhira kunoburitsa manzwi akaderera zvekuti mamwe haagone kunzwisiswa nenzeve yemunhu (pazasi pe20 Hz).
- Inzwi remurume mukuru murume. Kazhinji, izwi rechirume riri pakati pe100 ne200 Hz.
- Inzwi rebass. Vaimbi vechirume vanosarudzwa se "bass" ndeavo vanogona kuendesa zvinyorwa pakati pe75 ne350 Hz.
- Inzwi rebhesoni. Iyo bassoon chimbo chehuni chinogonesa ruzha rwakaderera se 62 Hz.
- Kurira kwetrombone. Iyo trombone chishongo chendarira icho chinowana manotsi akadzika se 73 Hz.
- C yeiyo octave 0. Ndiro ruzha rwepasi pasi rwakashandiswa mumumhanzi wekuMadokero. Kuwanda kwayo ndeye 16,351 Hz.
- Kana kubva paoctave 1. Kunyangwe paine angangoita mairi octave pamusoro peC ye octave 0, iyi B ichiri yakaderera kwazvo kurira, iine frequency ye 61.73 Hz.Iri iri kunyange pazasi pechinzvimbo chemuimbi webass.
Mienzaniso yemanzwi akakwirira
- Kurira kwevhayolini. Iyo violin chiridzwa chine tambo icho chinozadzisa imwe yeakanyanya kurira rwiyo mune orchestra (mushure mepiyano, iyo ine dzakasiyana siyana ruzha).
- Izwi revana. Vana vanowanzo kuve nemanzwi ari pamusoro pe250 kana 300 Hz. Kunyangwe iri renji risingapfuure zviuru zvishanu zveHz zvinowanzo fungidzirwa pamitinhimira yepamusoro, tinoona manzwi aya seakakwira-achienzaniswa nemanzwi evakuru.
- Izwi re soprano. Vaimbi vechikadzi vanozivikanwa se "sopranos" vanogona kuburitsa zvinyorwa pakati pe250 Hz ne1,000 Hz.
- Kana wechishanu wechisere. Ndiyo imwe yenzwi riripamusoro pane soprano yakadzidziswa inogona kusvika, iine frequency ye987.766 Hz.
- Rwiyo rwe shiri. Iko kushomeka kwekubuda kwakawanda kweshiri yehuswa ndeye1,000 Hz uye inosvika ma12,585 Hz.Kunyange iwo mafambiro akaderera ari pakati peanonyanya kurira achienzaniswa nezwi remunhu.
- Muridzo. Inowanzoita kutenderedza 1,500 Hz.
- Enderera ne: 10 Ruzha Unhu
