Isiginci se-Electro-acoustic: ukwakheka kwezinsimbi, isimiso sokusebenza, umlando, ukusetshenziswa

Ama-Bards, abaculi be-pop, ama-jazzmen bavame ukuthatha isiteji bephethe isiginci ezandleni zabo. Umuntu ongaziwa ngobuqili kanye nezici zokwenza amasu angase acabange ukuthi lokhu kuyi-acoustics evamile, efana ncamashi nezandla zabafana egcekeni noma abaculi be-novice. Kodwa empeleni, laba baculi badlala insimbi yomculo ekhokhelwayo ebizwa ngokuthi isiginci se-electro-acoustic.

Idivayisi

Umzimba ufana ne-acoustics yakudala - ukhuni olunama-wavy notches kanye nembobo eyindilinga ye-resonator ngaphansi kwezintambo. Intamo iphansi ohlangothini olusebenzayo futhi igcina ngekhanda elinezikhonkwane zokulungisa. Inani lezintambo liyahlukahluka kusuka ku-6 kuye ku-12.

Umehluko ngesiginci se-acoustic usezicini zesakhiwo sokubunjwa, ukuba khona kwezingxenye zikagesi ezinesibopho sokuguqulwa komsindo kanye nekhwalithi yomsindo. Lo mehluko ukuvumela ukuthi ukhiqize kabusha umsindo ocacile wesiginci se-acoustic ngevolumu ekhulisiwe.

I-piezo pickup ene-pickup ifakwa ngaphansi komngcele ngaphakathi kwekesi. Idivayisi efanayo itholakala kuziginci zikagesi, kodwa isebenza kumafrikhwensi ahlukene futhi isetshenziselwa kuphela izinsimbi ezinezintambo zensimbi.

Indawo yebhethri ifakwe eduze kwentamo ukuze umculi akwazi ukusebenza esiteji esingaxhumene namandla kagesi. I-timbral block iphahlazeka endaweni eseceleni. Unomthwalo wemfanelo wokulawula umsindo we-electroacoustics, ikuvumela ukuthi ulungise i-timbre, wandise amakhono obuchwepheshe bensimbi.

Isimiso sokusebenza

Isigingci sikagesi se-acoustic siyilungu lomndeni wezintambo. Umgomo wokusebenza uyafana nowe-acoustics - umsindo ukhishwa ngokuhlwitha izintambo noma ukuzishaya. Ubuhle be-electroacoustics kumakhono anwetshiwe wethuluzi. Ingadlalwa ngaphandle kokuxhunywa kugesi, okungenakwenzeka ngesiginci sikagesi. Kulokhu, umsindo uzofana nama-acoustics. Noma ngokuxhuma ku-mixer nemakrofoni. Umsindo uzosondela ku-elekthronikhi, ukhulume kakhulu, ujule.

Lapho umculi eqala ukudlala, izintambo ziyavevezela. Umsindo okhiqizwa yibo udlula kunzwa ye-piezo eyakhelwe esihlalweni. Itholwa yi-pickup futhi iguqulelwe kumasignali kagesi athunyelwa kubhlokhi yethoni. Lapho zicutshungulwa futhi zikhishwe nge-amplifier enomsindo ocacile. Kunezinhlobo ezahlukene zensimbi enezintambo ze-electro-acoustic ezinohlu oluthile lwezingxenye. Lawa angaba amashuna akhelwe ngaphakathi, imithelela yomsindo, isilawuli sokushaja ibhethri, ama-preamplifiers anezinhlobo ezahlukene zokulawula ithoni. Izilinganisi nazo ziyasetshenziswa, ezinamabhendi okushuna afika kwayisithupha amafrikhwensi afunekayo.

Umlando wesenzeko

Ukuqala kwekhulu lesi-XNUMX kwaphawulwa izivivinyo eziningi mayelana nokukhulisa ugesi kokudlidliza kwezintambo zomculo. Zazisekelwe ekuzivumelaniseni nezimo zama-transmitter ocingo kanye nokuqaliswa kwazo ekwakhiweni kwemishini. Ukuthuthukiswa kuthinte i-banjo ne-violin. Abaculi bazame ukukhulisa umsindo ngosizo lwemibhobho ye-push-button. Zazixhunywe kumbambi wezintambo, kodwa ngenxa yokudlidliza, umsindo wawuhlanekezelwe.

Isiginci se-electro-acoustic savela ngasekupheleni kweminyaka yama-30s ngaphambi kokuvela kwesiginci sikagesi. Amakhono ayo athakazelelwa ngokushesha ngabaculi abangochwepheshe abangenayo ivolumu yomculo okhiqizwe kabusha wokudlala “bukhoma”. Abaklami bathole izici ezifanele ngokuzama ngemibhobho ehlanekezele umsindo futhi bafake izinzwa zikagesi esikhundleni sawo.

Izincomo zokukhetha

Kunezinhlobo eziningi zeziginci ze-acoustic zikagesi. Kwabaqalayo, kungcono ukuqala ukufunda nge-acoustic yezintambo ezingu-6 ezivamile. Ochwepheshe basekelwe kulokho abakuthandayo, izici zokusetshenziswa, isidingo sokusebenza esiteji noma ku-studio yokuqopha. Ukuze uqonde ukuthi ungakhetha kanjani isiginci se-electro-acoustic, udinga ukwazi izici zedivayisi yayo. Umehluko omkhulu usezinzwa ezifakiwe. Bangaba:

• esebenzayo - inikwe amandla ngamabhethri noma ixhunywe ngentambo kagesi kusilawuli kude;
• i- passive – ayidingi amandla engeziwe, kodwa izwakale ithule.

Ngokwenziwa kwekhonsathi, kungcono ukuthenga insimbi ene-piezoelectric pickup esebenzayo. Lapho ukhetha, kufanele futhi ucabangele izinhlobo ezisetshenziswa ezinhlotsheni ezahlukene:

• i-jumbo - esetshenziswa "ezweni", inomsindo omkhulu;
• i-dreadnought - ehlukaniswa ngokuyinhloko kwamafrikhwensi aphansi ku-timbre, efanelekile ukwenza izingoma ezinhlotsheni ezahlukene kanye ne-solo;
• abantu - kuzwakala kuthule kune-dreadnought;
• i-ovation - eyenziwe ngezinto zokwenziwa, ezifanele ukusebenza kwekhonsathi;
• ihholo - ihlukile ezicini zekhwalithi zezingxenye eziyedwa.

Abadlali abazethembayo bangashintshela kusiginci esinezintambo ezingu-12. Kudinga ukufunda amasu okudlala athile, kodwa kunomsindo omkhulu, ocebile.

Ukusebenzisa

I-Electroacoustics iyithuluzi lokusetshenziswa kwendawo yonke. Ingasetshenziswa kokubili uma uxhumeke kunethiwekhi, futhi ngaphandle kwayo. Lona umehluko omkhulu phakathi kwelungu lomndeni wezintambo kanye nesiginci sikagesi, okungenakwenzeka ukudlala ngaphandle kokuxhunywa kwamandla kagesi.

Iziginci ze-Electro-acoustic zingabonakala ezandleni zika-Andrei Makarevich, u-Boris Grebenshchikov, u-frontman we-ChiZh ne-K band u-Sergei Chigrakov kanye no-soloist we-Nautilus u-Vyacheslav Butusov. Ayephethwe ngobuchule izihlabani ze-hard rock uKurt Cobain, uRitchie Blackmore, i-immortal Beatles. UJames nabaculi bomculo wesintu bathanda insimbi, ngoba, ngokungafani nesiginci se-acoustic, ikuvumela ukuthi uhambe ngokuthula esiteji, ungadali umculo kuphela, kodwa futhi nombukiso ogcwele.
