Yuav nrhiav dab tsi thaum xaiv hneev nti?

Ntxiv nrog rau qhov zoo ntawm cov cuab yeej thiab kev xaiv cov hlua uas tsim nyog, hneev taw yog qhov tseem ceeb rau tus nqi ntawm lub suab. Ua ntej tshaj plaws, nws cov khoom ergonomic tuaj yeem pab txhawb lossis cuam tshuam kev ua si, thiab peb cov kev tsim kho kev ua haujlwm yuav ua rau muaj kev xav tau ntau dua ntawm hneev nti - ntxiv rau kev ua si ib txwm muaj, yuav muaj dhia hneev, thiab cov khoom siv tsis txaus yuav ua rau nws ntau dua. nyuaj rau peb kawm lawv.

Ntau hom violin, viola, cello thiab ob chav ntses bass thaj tsam muaj nyob rau hauv khw.

Thawj qhov kev xaiv pom tseeb yog qhov loj ntawm hneev nti. Xaiv qhov loj me me piv rau qhov loj ntawm peb qhov ntsuas. Cov kev pabcuam hauv khw muag khoom yuav pab peb nrog kev sib tw. Peb tuaj yeem kuaj xyuas nws tus kheej raws li hauv qab no: peb tuav lub twj paj nruag zoo li ua si, muab tus hneev nti rau ntawm cov hlua thiab rub tus hneev taw kom txog thaum txhais tes ncaj nraim - hneev tsis tuaj yeem ploj, peb yuav tsum ua kom tiav qhov kev txav mus los tsuas yog ntawm tes. lub ntsiab lus - ces peb paub tias hneev yog ntawm qhov ntev.

Technical Properties ntawm cov hlua

Lwm qhov tseem ceeb uas qhov txawv ntawm bows yog cov khoom uas lawv tau ua los ntawm. Muaj ntoo, fiber ntau thiab carbon composite bows.

Cov hlua fiber ntau tsuas yog muaj rau violas thiab violins. Cov no yog cov tub ntxhais kawm pheej yig nyo hau heev rau deformation thiab yeej tsis muab txoj kev ywj pheej los tsim lub suab. Txawm li cas los xij, hauv thawj xyoo ntawm kev kawm, ua ntej peb kawm kom ua haujlwm tau zoo, nws yog ib qho kev xaiv txaus.

Carbon composite fiber bows yog lwm lub txee hauv cov khoom zoo. Lawv hloov tau ntau dua, muaj zog thiab ruaj khov dua, tab sis tsis muaj dab tsi tuaj yeem hloov lub hneev ntoo. Lawv qhov zoo kuj txawv heev vim muaj ntau hom ntoo siv hauv kev tsim khoom.

Peb paub qhov txawv ntawm txoj hlua khi ua los ntawm fernambul ntoo (tseem paub tias yog qhov zoo tshaj plaws), ntoo nab thiab ntoo Brazilian. Fernambuk yog qhov zoo tshaj plaws rau nws zoo meej elasticity thiab tsis kam mus deformation. Cov hlua khi kuj yog ua los ntawm ntau yam ntaub ntawv - yav dhau los nws yog ivory, fernambuc ntoo lossis ebony, niaj hnub no feem ntau yog ua los ntawm cov pob txha nyuj, ebony, rosewood lossis ntoo los ntawm cov pas nrig. rau hneev - lub taub hau, nws yuav tsum tsis txhob nyias thiab muag heev, vim hais tias nws tuav tag nrho cov nro ntawm bristles. Lub bar ntawm hneev yuav muaj ib puag ncig, octagonal los yog, tsawg zaus, grooved cross-section. Nws tsis cuam tshuam rau lub suab lossis qhov zoo.

Lub cev muaj zog ntawm cov hlua

Thawj qhov uas peb yuav tsum tau them sai sai rau thaum xaiv qhov ntev thiab cov khoom siv ntawm hneev yog nws cov duab - lub hneev tsis tuaj yeem nkhaus. Yuav kuaj li cas? Tighten lub bristles, muab tus hneev nrog tus qav ntsia hlau rau ntawm qhov muag thiab, kaw lub qhov muag, saib ntawm qhov taw tes - tus hneev tsis tuaj yeem khoov rau hauv ib qho kev taw qhia.

Qhov hnyav ntawm hneev taw kuj tseem ceeb. Ua ntej tshaj plaws, yuav tsum ceev faj thaum xaiv tus hneev rau tus pib ntaus suab paj nruag, vim hais tias cov tub ntxhais kawm pheej yig bows feem ntau yog lub teeb heev thiab tuaj yeem thaws thaum ua si, uas yuav cuam tshuam lub suab txuas ntxiv, thaum hnyav heev hneev yuav nrawm tes. Nws tseem yog ib qho tsim nyog los txiav txim qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm hneev nti. Rau lub hom phiaj no, peb muab nws kab rov tav rau ntawm tus ntiv tes txuas ntxiv thiab ua qhov hu ua "Qhov hnyav" - peb yuav tsum nrhiav qhov chaw uas tus hneev yuav nyob hauv kab rov tav yam tsis poob mus rau ob sab. Feem ntau, qhov chaw no yog me ntsis hauv qab qhov chaw, mus rau Qav. Kev tsis pom txoj haujlwm no tuaj yeem txhais tau tias hneev nti tawm ntawm qhov sib npaug.

Sib nrug los ntawm kev dhia, hneev taw yuav tsum tau ua kom yooj yim, yooj yim rau kev ua haujlwm zoo, nws yuav tsum tsis txhob vibrate ntawm qhov taw tes, thiab nws yuav tsum tsis txhob ua rau khawb ntawm tus qav. Nws yog qhov pom tseeb tias kev kuaj xyuas hneev nti zoo kuj yog nyob ntawm qhov kev txawj ntawm cov neeg ua si, yog li peb cov kev xav tau ntawm cov cuab yeej loj hlob tuaj, tsis txhob ntshai nug tus kws tshaj lij tshuab raj rau kev pab. Lub bar ntawm hneev yuav tsum yoog raws, tsis nruj heev, thiab cov bristles yuav tsum xoob kiag li.

Cov Bristles

Thaum kawg ntawm peb txoj kev kawm ntawm tus hneev taw, cia peb xyuas seb nws puas muaj bristles - cov plaub hau strip yuav tsum tau muab sib npaug sib npaug, dav, tsis pom cov bulges. Qhov no yog qhov tseem ceeb tshaj plaws, vim hais tias cov bristles ntawm luthier tuaj yeem hloov lawv txhua lub sijhawm.

Hneev nti yog ib yam khoom muag heev thiab yuav tsum tau ua kom zoo. Nco ntsoov tias cov bristles tsis nruj heev - lub hneev ntawm hneev yuav tsum ib txwm ua ib qho arc (lub plab tig rau lub bristles, tsis yog lwm txoj hauv kev!). Tom qab txhua qhov kev tawm dag zog, cia peb loosen cov bristles, vim tias nyob rau hauv qhov kub thiab av noo, nws tuaj yeem txo qis los ntawm nws tus kheej thiab tseem ua rau lub bar tawg, thiab qhov xwm txheej no feem ntau tsis muaj kev daws teeb meem.

Nws tseem yog ib qho tseem ceeb uas yuav tsum tswj kom zoo adhesion ntawm cov bristles los ntawm lubricating lawv nrog rosin thiab ua kom lawv huv si. Tsis txhob kov cov bristles nrog koj cov ntiv tes, vim tias av tshem tawm nws cov nplaum thiab roughness, uas yog nws cov khoom tseem ceeb tshaj plaws.
