gitala Electro-acoustic: zida zikuchokera, mfundo ntchito, mbiri, ntchito

Bards, oimba a pop, jazzmen nthawi zambiri amatenga siteji ndi gitala m'manja mwawo. Munthu amene sadziwa zobisika ndi peculiarities wa luso luso angaganize kuti ndi mawu wamba, chimodzimodzi monga m'manja mwa anyamata pabwalo kapena novice oimba. Koma kwenikweni, akatswiriwa amasewera chida choimbira chodziwika bwino chotchedwa electro-acoustic guitar.

chipangizo

Thupi ndilofanana ndi ma acoustics apamwamba - matabwa okhala ndi ma wavy notches ndi dzenje lozungulira la resonator pansi pa zingwe. Khosi ndi lathyathyathya kumbali yogwira ntchito ndipo limatha ndi mutu wokhala ndi zikhomo zowongolera. Chiwerengero cha zingwe zimasiyanasiyana kuchokera 6 mpaka 12.

Kusiyanitsa ndi gitala lamayimbidwe kumapangidwa ndi mawonekedwe ake, kukhalapo kwa zida zamagetsi zomwe zimayang'anira kutembenuka kwa mawu komanso kumveka bwino. Kusiyanaku kumakupatsani mwayi wotulutsanso mawu omveka bwino a gitala lamayimbidwe ndi voliyumu yokwezeka.

Chojambula cha piezo chokhala ndi chojambula chimayikidwa pansi pa khomo mkati mwa mlanduwo. Chipangizo chofananacho chimapezeka pa magitala amagetsi, koma chimagwira ntchito mosiyanasiyana ndipo chimangogwiritsidwa ntchito pazida zokhala ndi zingwe zachitsulo.

Chipinda cha batri chimayikidwa pafupi ndi khosi kuti woimbayo azitha kugwira ntchito pa siteji yomwe sichikugwirizana ndi mphamvu zamagetsi. Chophimba cha timbral chimagwera m'mbali mwake. Iye ali ndi udindo wowongolera phokoso la electroacoustics, amakulolani kusintha timbre, kukulitsa luso lachidacho.

Mfundo yogwirira ntchito

Gitala yamagetsi yamagetsi ndi membala wa banja la zingwe. Mfundo yogwira ntchito ndi yofanana ndi ya ma acoustics - phokoso limachotsedwa podula zingwe kapena kuzimenya. Ubwino wa electroacoustics mu mphamvu zowonjezera za chida. Itha kusewera popanda kulumikizidwa ndi magetsi, zomwe sizingatheke ndi gitala lamagetsi. Pankhaniyi, phokoso lidzakhala lofanana ndi ma acoustics. Kapena polumikizana ndi chosakaniza ndi maikolofoni. Phokoso lidzayandikira pafupi ndi zamagetsi, mokweza, juicier.

Woimba akayamba kuimba, zingwe zake zimanjenjemera. Phokoso lopangidwa ndi iwo limadutsa mu sensa ya piezo yomangidwa mu chishalo. Zimalandiridwa ndi kujambula ndikusinthidwa kukhala zizindikiro zamagetsi zomwe zimatumizidwa ku block tone. Kumeneko amakonzedwa ndikutuluka kudzera mu amplifier ndi mawu omveka bwino. Pali mitundu yosiyanasiyana ya zida za electro-acoustic zokhala ndi mndandanda wazinthu zina. Izi zitha kukhala ma tuner omangidwira, zomveka, kuwongolera kwa batire, ma preamplifiers okhala ndi mitundu yosiyanasiyana yowongolera ma toni. Ma Equalizer amagwiritsidwanso ntchito, okhala ndi magulu asanu ndi limodzi osinthira ma frequency omwe mukufuna.

Mbiri yazomwe zachitika

Kumayambiriro kwa zaka za zana la XNUMX kudadziwika ndi zoyeserera zingapo pakukula kwamagetsi kwa kugwedezeka kwa zingwe za zida. Zinakhazikitsidwa pakusintha kwa ma transmitter amafoni komanso kukhazikitsidwa kwawo pamapangidwe a zida. Kuwongolera kudakhudza banjo ndi violin. Oimbawo anayesa kukulitsa mawuwo pogwiritsa ntchito maikolofoni okankha batani. Anamangidwira ku chogwirizira chingwe, koma chifukwa cha kugwedezeka, phokosolo linasokonezedwa.

Gitala ya electro-acoustic idawonekera kumapeto kwa zaka za m'ma 30s kale gitala lamagetsi lisanawonekere. Mphamvu zake zidayamikiridwa nthawi yomweyo ndi akatswiri oimba omwe analibe nyimbo zomwe zidapangidwanso kuti ziwonetsedwe "zamoyo". Okonzawo adapeza mikhalidwe yoyenera poyesa maikolofoni omwe amasokoneza mawuwo ndikuyika ma sensor a electromagnetic.

Malangizo pakusankha

Pali mitundu yambiri ya magitala apamagetsi. Kwa oyamba kumene, ndi bwino kuyamba kuphunzira ndi ochiritsira 6-zingwe acoustic. Akatswiri amatengera zomwe amakonda, mawonekedwe ogwiritsira ntchito, kufunikira kogwira ntchito pa siteji kapena mu studio yojambulira. Kuti mumvetse momwe mungasankhire gitala la electro-acoustic, muyenera kudziwa mawonekedwe a chipangizo chake. Kusiyana kwakukulu kuli mu masensa omwe adayikidwa. Iwo akhoza kukhala:

• yogwira ntchito - yoyendetsedwa ndi mabatire kapena yolumikizidwa ndi chingwe chamagetsi ku chiwongolero chakutali;
• kungokhala chete - sikufuna mphamvu zowonjezera, koma kumveka chete.

Paziwonetsero zamakonsati, ndikwabwino kugula chida chokhala ndi chojambula cha piezoelectric. Posankha, muyenera kuganiziranso mitundu yomwe imagwiritsidwa ntchito m'mitundu yosiyanasiyana:

• jumbo - yogwiritsidwa ntchito mu "dziko", imakhala ndi phokoso lalikulu;
• dreadnought - yosiyanitsidwa ndi kuchuluka kwa ma frequency otsika mu timbre, oyenera kuyimba nyimbo zamitundu yosiyanasiyana ndi solo;
• anthu - amamveka chete kuposa dreadnought;
• ovation - zopangidwa ndi zipangizo zopangira, zoyenera kuchita masewera olimbitsa thupi;
• holo - amasiyana mu mawonekedwe amtundu wa solo.

Osewera odzidalira amatha kusintha kukhala gitala lazingwe 12. Zimafunika kuphunzira luso lamasewera, koma zimakhala ndi mawu abwino, olemera.

kugwiritsa

Electroacoustics ndi chida chogwiritsidwa ntchito padziko lonse lapansi. Itha kugwiritsidwa ntchito polumikizidwa ndi netiweki, komanso popanda izo. Ichi ndicho kusiyana kwakukulu pakati pa membala wa banja la zingwe ndi gitala lamagetsi, zomwe sizingatheke kusewera popanda kugwirizana ndi magetsi.

Electro-acoustic guitars zitha kuwoneka m'manja mwa Andrei Makarevich, Boris Grebenshchikov, mtsogoleri wa gulu la ChiZh ndi K Sergei Chigrakov ndi woyimba solo wa Nautilus Vyacheslav Butusov. Iwo anali mwaluso kwambiri ndi akatswiri a rock olimba Kurt Cobain, Ritchie Blackmore, The Immortal Beatles. Jamen ndi oimba nyimbo zamtundu wamtunduwu adakonda chidacho, chifukwa, mosiyana ndi gitala lamayimbidwe, amakulolani kuti muziyenda mozungulira siteji, osapanga nyimbo zokha, komanso chiwonetsero chathunthu.
