Yuav ua li cas xaiv lub piano rau tus menyuam

Niaj hnub no peb yuav tham txog yuav ua li cas xaiv lub piano yog tias koj tsis muaj kev paub tshwj xeeb hauv cheeb tsam no, peb yuav pom tias koj yuav tsum saib dab tsi thiab qhov twg tuaj yeem tsis quav ntsej. Peb yuav tham ntawm no tshwj xeeb txog kev xaiv lub piano acoustic (tsis yog digital).

Tau kawg, qhov kev xaiv muaj txiaj ntsig tshaj plaws yog kev sab laj nrog tus kws tuner tshwj xeeb uas nkag siab txog cov tshuab ntawm lub piano thiab tuaj yeem yooj yim rau lub hlwb disassemble lub twj paj nruag uas koj muaj koj lub qhov muag. Ntxiv mus, tuners feem ntau tuaj yeem qhia koj qhov twg koj tuaj yeem yuav lub piano zoo tshaj plaws rau tus nqi qis.

Tab sis, raws li txoj cai, tuners yog cov kws tshawb fawb tshwj xeeb uas nws yuav luag tsis tuaj yeem nrhiav lawv dawb (feem ntau, txawm tias nyob hauv lub nroog loj, cov tuners zoo tuaj yeem suav ntawm ib sab tes, tab sis hauv lub nroog me lossis lub zos yuav tsis muaj. ua ib qho ntawm lawv txhua). Tsis tas li ntawd, rau kev pab hauv kev xaiv ib qho cuab yeej, koj tuaj yeem tiv tauj tus kws qhia pianist los ntawm lub tsev kawm suab paj nruag, uas, tau ntsuas lub piano raws li qee qhov ntawm nws cov qauv, yuav tuaj yeem qhia tau tias qhov ntsuas no haum rau koj lossis tsis.

Yog tias tsis muaj leej twg nug txog qhov teeb meem no, koj yuav tsum xaiv lub piano koj tus kheej. Thiab nws zoo yog tias koj tsis yog tus kws tshaj lij hauv qhov teeb meem no, thiab tseem tsis tau kawm hauv tsev kawm suab paj nruag. Muaj cov txheej txheem uas koj, tsis muaj kev kawm suab paj nruag lossis kev txawj ntse, tuaj yeem txiav txim siab qhov tsim nyog ntawm cov cuab yeej siv ntxiv. Peb, ntawm chav kawm, tham txog siv twj paj nruag; yuav muaj ob peb lo lus hais txog cov tshiab tom qab.

Ua ntej ntawm tag nrho cov, cia peb dispel ib co preconceptions. Hauv kev tshaj tawm rau kev muag khoom ntawm lub piano, cov yam ntxwv hauv qab no feem ntau sau: suab zoo, hauv suab, xim av, hom npe, antique, nrog candelabra, thiab lwm yam. Tag nrho cov yam ntxwv zoo li no, nrog rau kev zam, tej zaum, ntawm hom, yog. ua kom tsis muaj tseeb, yog li lawv tsuas yog tsis tas yuav tsum coj mus rau hauv tus account, yog tias tsuas yog rau qhov tseeb tias lub piano zoo tshaj plaws yog tawm ntawm lub suab thaum lub sijhawm thauj mus los thiab "lub suab zoo" yog deb ntawm qhov tshwm sim tas li thiab ntau lub tswv yim muaj txiaj ntsig. Peb yuav ntsuas lub piano ntawm qhov chaw thiab ntawm no yog qhov koj yuav tsum tau them sai sai rau.

tsos

Qhov tshwm sim yog qhov taw qhia thawj zaug: yog tias cov cuab yeej zoo li tsis zoo nkauj thiab sloppy, ces tus menyuam yuav tsis nyiam nws (thiab cov menyuam yaus yuav tsum hlub lawv cov khoom). Tsis tas li ntawd, los ntawm nws cov tsos, koj tuaj yeem txiav txim siab qhov chaw thiab tej yam kev mob uas lub piano nyob. Piv txwv li, yog hais tias lub veneer tawm los, qhov no txhais tau hais tias lub twj paj nruag thawj zaug raug waterlogging thiab ces qhuav tawm. Raws li qhov kev ntsuas no, tsis muaj dab tsi ntxiv: yog tias peb nyiam nws, peb yuav saib ntxiv, yog tias tsis yog, peb yuav txav mus rau kev tshuaj xyuas tom ntej.

Mloog rau lub suab

Lub timbre ntawm lub piano yuav tsum qab ntxiag, tsis annoying. Yuav ua li cas? Nov yog dab tsi: peb mloog txhua daim ntawv, nias tag nrho cov yuam sij dawb thiab dub ua ke, ib qho tom qab ntawm cov keyboard ntawm sab laug mus rau sab xis, thiab ntsuas lub suab zoo. Yog tias muaj qhov tsis xws luag xws li khob tsis siv lub suab, lub suab sib txawv ntawm qhov ntim, lossis lub suab los ntawm qee cov yuam sij yog luv heev (Kuv tsis txhais hais tias cov ntaub ntawv sab saud ntawm sab xis ntawm cov keyboard), ces tsis muaj qhov taw qhia txuas ntxiv. kev tshuaj xyuas. Yog tias ob tus yuam sij tsim lub suab ntawm tib lub suab, lossis yog tias ib qho tseem ceeb ua kom muaj kev sib txuas ntawm ob lub suab sib txawv, ces koj yuav tsum ceev faj thiab txuas ntxiv mus soj ntsuam (ntawm no koj yuav tsum nkag siab qhov laj thawj).

Yog hais tias, nyob rau hauv Feem ntau, lub suab nrov heev, rattling thiab nrov, nws tsis yog heev qab ntxiag rau lub pob ntseg (lub suab phem ua rau cov me nyuam los ntawm kev kawm thiab muaj tib yam irritating nyhuv ntawm lub hlwb, xws li, piv txwv li, buzzing ntawm ib tug yoov tshaj cum. ). Yog hais tias cov ntoo ntawm cov cuab yeej yog mos thiab npub, qhov no yog qhov zoo; Qhov zoo tshaj plaws yog thaum lub dullness ntawm lub suab ua ke nrog nws cov ntim nruab nrab (tsis ntsiag to thiab tsis nrov dhau).

Kuaj cov keyboard

 Cia peb mus dhau txhua tus yuam sij hauv kab ib zaug ntxiv, tam sim no txhawm rau txheeb xyuas seb lawv puas nkag mus rau tib qhov tob, txawm tias tus yuam sij hauv dab dej (uas yog, tau daig), thiab seb cov yuam sij khob rau hauv qab ntawm cov keyboard. Yog tias tus yuam sij tsis raug nias txhua, qhov teeb meem no tuaj yeem kho tau yooj yim, tab sis koj yuav tsum ceev faj. Ntsuas lub teeb ntawm cov keyboard - nws yuav tsum tsis txhob nruj heev (cov keyboards no txaus ntshai rau cov pib pianists) thiab lub teeb dhau (uas qhia tau hais tias hnav ntawm cov khoom siv).

Saib ntawm cov keyboard saum toj thiab los ntawm sab - saum npoo ntawm txhua tus yuam sij yuav tsum nyob ntawm tib lub dav hlau; Yog hais tias qee cov yuam sij protrude saum lub dav hlau no los yog, qhov sib txawv, me ntsis qis dua tus txheeb ze rau qib no, ces qhov no yog qhov phem, tab sis kho tau heev.

Tshawb xyuas lub piano sab hauv

Koj yuav tsum tshem tawm cov ntaub thaiv sab saum toj thiab hauv qab thiab cov keyboard npog. Sab hauv ntawm lub piano zoo li no:

Cov yuam sij uas peb pom sab nraud yog qhov tseeb tsuas yog levers rau kev txav mus rau rauj, uas nyob rau hauv lem kis lub tshuab mus rau txoj hlua - lub hauv paus ntawm lub suab. Cov khoom tseem ceeb tshaj plaws ntawm cov qauv sab hauv ntawm lub piano yog ib qho qauv nrog cov tshuab (hammers thiab txhua yam nrog lawv), cov hlua thiab cov hlau thav duab ("harp nyob rau hauv lub hleb"), pegs uas cov hlua yog screwed thiab ntoo soundboard.

 Deca-resonator thiab mechanics

Ua ntej ntawm tag nrho cov, peb tshuaj xyuas lub resonator lawj - ib tug tshwj xeeb board ua los ntawm coniferous ntoo. Yog tias nws muaj cov kab nrib pleb (muaj cov kab nrib pleb hauv qab) - lub piano tsis zoo (nws yuav rattle). Tom ntej no peb tsiv mus rau mechanics. Cov kws tshaj lij tuners nkag siab txog cov tshuab, tab sis koj tuaj yeem tshawb xyuas seb cov ntaub thiab cov ntaub npog puas yog npauj noj thiab seb cov rauj puas xoob (manually co txhua rauj). Lub piano tsuas muaj 88 hammers, nrog rau cov yuam sij (qee zaum 85) thiab yog tias ntau tshaj 10-12 ntawm lawv wobbly, ces nws yuav zoo li tias tag nrho cov fastenings nyob rau hauv mechanics tau xoob thiab qee qhov chaw yuav poob (txhua yam tuaj yeem ua tau. yuav nruj, tab sis qhov twg yog qhov lav? , uas nyob rau hauv ib lub lis piam cov tshiab yuav tsis wobble?).

Tom ntej no, koj yuav tsum mus dhau txhua tus yuam sij ua ke dua, xyuas kom txhua tus rauj txav mus rau hauv kev sib cais thiab tsis txhob kov cov neeg nyob sib ze. Yog hais tias nws kov, ces qhov no kuj yog ib tug kos npe rau ntawm tsis muaj zog mechanics thiab pov thawj hais tias lub piano tsis tau tu ncua ntev. Lub rauj yuav tsum thaws tawm ntawm txoj hlua tam sim ntawd tom qab ntaus nws, thiab lub suab yuav tsum ploj mus sai li sai tau thaum koj tso tus yuam sij (tam sim no nws lub muffler, lub npe hu ua damper, txo qis rau txoj hlua). Qhov no yog, tej zaum, txhua yam uas koj tuaj yeem tshawb xyuas ntawm koj tus kheej hauv mechanics, tsis muaj lub tswv yim txog nws txoj haujlwm thiab cov qauv, uas kuv yuav tsis piav qhia hauv tsab xov xwm no.

Cov hlua

Peb tam sim ntawd xyuas cov hlua ntawm cov hlua, thiab yog tias ib qho ntawm cov hlua ploj lawm, ces koj yuav tsum nug tus tswv qhov twg nws mus. Ua li cas koj thiaj paub yog tias tsis muaj cov hlua txaus? Nws yog qhov yooj yim heev - vim muaj qhov sib txawv loj heev ntawm cov hlua thiab lub peg tsis muaj. Tsis tas li ntawd, yog tias txoj hlua ntawm lub peg tau ruaj ntseg nyob rau hauv txoj kev txawv txav (piv txwv li, tsis yog ib qho kev sib tw, tab sis lub voj voog), ces qhov no qhia tias txoj hlua tawg yav dhau los (qee zaum kev tawg tuaj yeem tshawb pom los ntawm cov xov tooj ntawm cov hlua hauv " hu nkauj” (uas yog, ib pawg ntawm 3 txoj hlua) - thaum tsis muaj peb ntawm lawv, tab sis tsuas yog ob, ncab obliquely).

Yog hais tias lub piano ploj lawm tsawg kawg yog ob txoj hlua los yog muaj qhov pom tseeb ntawm kev so yav dhau los, ces cov piano zoo li no yuav tsum tsis txhob yuav nyob rau hauv ib qho xwm txheej, vim tias feem ntau ntawm cov hlua nyias nyias yuav poob rau xyoo tom ntej.

Muaj pes tsawg

Tom ntej no, peb xyuas cov pegs uas cov hlua txuas. Nws yog qhov tseeb tias los ntawm kev tig lub pegs (qhov no yog ua tiav siv tus yuam sij tuning), peb kho lub suab ntawm txhua txoj hlua. Pegs yuav tsum tau kho txoj hlua zoo li no thaum nws vibrates nws tsim lub suab tshwj xeeb. Thiab yog hais tias lub pegs tsis kho qhov nro ntawm cov hlua zoo, ces lub piano tag nrho tsis nyob twj ywm (uas yog, kho nws yuav luag tsis muaj txiaj ntsig).

Tau kawg, koj tsis zoo li pom pegs uas ncaj qha wobbly lossis ntog tawm (thiab qee zaum nws txawm los rau qhov no). Qhov no yog ntuj, vim hais tias cov pegs yog txuas nrog ib tug ntoo beam, thiab ntoo tuaj yeem qhuav tawm thiab deformed. Lub qhov (sockets) uas cov pegs tau ntxig tuaj yeem nthuav dav dhau sijhawm (cia peb hais tias cov cuab yeej qub tau hloov kho ib puas zaug thaum nws "lub neej"). Yog tias koj, tshuaj xyuas lub pegs, pom tias ib lossis ob ntawm tag nrho lub txhab nyiaj muaj qhov txawv txav (loj dua tag nrho lwm tus), yog tias qee qhov ntawm cov pegs yog skewed, lossis yog tias koj pom tias lwm yam raug tso rau hauv lub qhov (socket) dua li lub peg. nws tus kheej (khoom ntawm veneer, ib co wrapper rau peg), ces khiav deb ntawm xws li ib tug piano - nws twb tuag lawm.

Zoo, qhov ntawd yog txhua yam - ntau tshaj qhov txaus los yuav ib qho cuab yeej siv tau. Rau qhov no koj tuaj yeem tshawb xyuas cov haujlwm ntawm sab xis thiab sab laug pedals; Txawm li cas los xij, lawv cov haujlwm ua haujlwm tau yooj yim heev los kho yog tias muaj qee yam tsis raug.
