Qhov kev sib haum xeeb yog qhov tseem ceeb tshaj plaws rau cov kws ntaus suab paj nruag. Txoj kev no tshwm sim li cas? Koj tuaj yeem ua cov twj paj nruag dab tsi thiab koj tuaj yeem kawm ua si txhua yam kev sib haum xeeb ntawm lub guitar? Dab tsi yog txoj hauv kev ua qhov no? Cia peb nrog cov lus nug no thiab kawm qhov kev dag no!

Flageolet - nws yog dab tsi hauv suab paj nruag?

Txhua tus kws ntaus suab paj nruag pib qee qhov thiab maj mam paub ntau ntxiv thiab ntau cov tswv yim tshiab uas ua rau nce qib ntawm nws qhov kev ua si thiab nws qhov kev ua tau zoo.

Pharmaceutical yog cov txheej txheem suab paj nruag uas ua los ntawm cov cuab yeej siv hlua. Nrog nws, koj tuaj yeem tau txais lub suab mos thiab airy. Cov txheej txheem zoo li no yuav ntxiv cov xim tshiab rau kev ua si ntawm cov twj paj nruag, thaum lub suab sib txawv ntawm lub suab los ntawm lub suab thaum txoj hlua yog tag nrho nias, thiab los ntawm qhov pom ntawm physics, sib txawv vibrations tshwm sim. Kev txais tos yog siv nyob rau hauv ntau yam suab paj nruag, tshwj xeeb yog them rau nws nyob rau hauv lub pob zeb nyuaj, qhov twg nws yog ua nyob rau hauv ib tug hluav taws xob guitar. Harmonics yog cov txheej txheem nyiam rau solo hlau guitarists.

Tom ntej no, cia peb mus saib qhov sib txawv ntawm cov hom kev sib haum xeeb, ob qho tib si hauv kev ua haujlwm thiab lub suab. Piv txwv li, ntawm cov twj paj nruag cua, kev sib haum xeeb sib haum rau qee txoj hauv kev ua si, uas muaj nyob rau hauv tshuab tsis yog tus qauv overtones, uas yog ua tiav los ntawm lub siab tawv.

Los ntawm keeb kwm ntawm qhov tsos

thawj daim uas paub siv cov txheej txheem no yog qhov thib plaub opus Lessonsharmonique los ntawm Fab Kis tus kws ntaus suab paj nruag Jean-Joseph Mondonville.

Nws tsuas muaj qhov sib haum xeeb xwb. Txij thaum ntawd los, cov txheej txheem ntawm kev ua tau zoo lawm, hom tshiab tau tshwm sim, koj tuaj yeem kawm ntau yam los ntawm kev ua haujlwm ntawm Italian composer Salvatore Scirrino. Tom qab ntawd, ntau qhov sib haum xeeb thiab txawm tias muaj kev sib haum xeeb chords tshwm sim, uas, txawm tias lub npe, tau tsim thiab coj los ntawm ib txoj hlua. Thiab nyob rau hauv lub xyoo pua 20th nws tau nyiam siv harmonics hauv cov txheej txheem ntawm kev ua si piano, lawv tuaj yeem hnov hauv ntau yam haujlwm los ntawm George Kram.

Muaj ob lub ntsiab ntawm flageolets - ntuj thiab dag. Ntuj sawv daws sib raug rau cov hlua qhib, thiab cov khoom siv dag zogtshwm sim nias rau lub fret. Yog tias koj nkag siab txog physics ntawm cov txheej txheem ntawm cov tsos ntawm flageolet, ces tsis muaj qhov sib txawv ntawm oscillations nyob ntawm seb hom flageolet, tab sis muaj qhov sib txawv ntawm qhov nyuaj ntawm lawv qhov kev tua. Nws yooj yim dua kom kawm paub ua cov kev sib raug zoo ntawm ntuj tsim.

Dhau li ntawm qhov kev faib tawm no, flageolets tseem tuaj yeem raug cais raws li txoj kev rho tawm. Cov hom hauv qab no yog qhov txawv ntawm no:

  1. ntiv tes (nws tuaj yeem yog ntuj lossis tsim kev sib haum xeeb).
  2. Plectrum (tau nrog tus xaiv)
  3. Semi-harmonic - ob lub suab tau txais ntawm ib txoj hlua los ntawm kev sib chwv cov hlua, los ntawm ob qho tib si lub suab nrov thiab lub suab sib haum xeeb.

Ntxiv rau, ib hom ntxiv tuaj yeem paub qhov txawv - cov no yog cov flageolets nyuaj. Lawv yog cov khoom sib xyaw ua ke, ua tiav los ntawm kev sib txuas. Thaum lawv ua yeeb yam, sab tes xis yog koom nrog ob qho tib si hauv kev ua si ntawm kev sib haum xeeb ntawm lawv tus kheej thiab hauv kev ua suab paj nruag rau lawv.

Yuav ua li cas ua kom sib haum xeeb ntawm guitar?

Los ntawm rub txoj hlua qhib los yog nruj nreem kaw ntawm lub ntsuas, koj tuaj yeem pom qhov zoo li ntawm kev vibrations. Lub suab no yog lub hauv paus, thiab lub suab sib haum xeeb ntawm lub guitar yog ib qho overtone, ib qho seem overtone uas tsis suav nrog hauv paus. Hauv qhov no, oscillations txawv ntawm oscillations ntawm ib txoj hlua qhib. Lub overtone yeej ib txwm siab tshaj lub hauv paus.

Lub hauv paus ntsiab lus ntawm kev sib haum xeeb yog tus neeg ua yeeb yam ntiv tes, xoob nias rau txoj hlua, poob tawm tag nrho cov overtones tsuas yog ib qho. Ua li no, nws yog ib qho tseem ceeb uas yuav tsum tau kov koj tus ntiv tes kom meej meej nyob rau hauv qhov chaw ntawm qhov me me vibration ntawm txoj hlua. Nco ntsoov tias tej zaum yuav muaj ntau qhov chaw.

Natural harmonics ntawm lub guitar yog coj los ntawm maj mam kov cov hlua ntawm cov ntsiab lus ntawm kev faib, thiab cov khoom siv dag zog - ntawm ib txoj hlua nruj nreem, thaum lwm tus ntiv tes maj mam kov cov hlua nyob rau hauv lub sij hawm ntawm ib quart los yog thib tsib los ntawm tus ntiv tes nruj nias thawj zaug.

Natural harmonic technique

Natural harmonics ntawm lub guitar tuaj yeem ua tau yog tias koj nyuam qhuav kov txoj hlua ntawm kaum ob, cuaj, xya, tsib, plaub, thib peb frets nrog koj sab tes xis, thaum rub txoj hlua nrog koj sab tes xis. Txawm li cas los xij, hom kev sib haum xeeb no feem ntau tshwm sim ntawm qhov thib tsib, xya thiab kaum ob frets, txij li lawv faib cov hlua guitar rau hauv qhov sib npaug. Txhawm rau rho tawm nws, koj yuav tsum tau kov nrog tus ntiv tes ntawm koj sab laug tes hla txoj kab fret ntawm frets (piv txwv li, thib tsib thiab thib rau thiab ntxiv los ntawm kev sib piv), thaum lub fret tsis tas yuav tsum tau clamped. Ib tug tshiab guitarist tuaj yeem ua qhov no yam tsis muaj kev cob qhia ntxiv, qhov tseem ceeb tshaj plaws yog tsis txhob tso siab rau txoj hlua, lub suab yuav tsum yog lub teeb thiab mos.

Nyob rau hauv cov ntawv, nws yog sau nrog kev pab los ntawm ib tug tshwj xeeb tsim Fl (nyob rau hauv Soviet tsab - FL), thiab lub taub hau ntawm daim ntawv muaj cov duab ntawm ib tug rhombus (rau tus ntiv tes txoj kev) thiab daim duab peb sab (rau tus neeg nruab nrab). Nws zoo li no: Fl. VII (uas yog, tus flageolet tau sau ntawm no rau ntawm xya fret). Hauv kev tshaj tawm txawv teb chaws, kev tsim kev puas tsuaj (caj npab) yog siv. Lub suab ntawm daim ntawv sib haum mus rau lub suab ntawm lub harmonic.

Artificial harmonic technique

Technically, cov txheej txheem no nyuaj rau kev siv, vim tias thaum ua si lub ntujntawm kev sib haum xeeb, sab laug tes pab txoj cai, thaum lub sijhawm txoj cai nres lub suab nrog kov. Ntawm no nws yog tsis yooj yim sua, vim hais tias nws yog nias tawm tsam lub bar. Txhawm rau ua cov txheej txheem no, koj yuav tsum tsis txhob kov lub kaum ob fret nrog tus ntiv tes xoo ntawm sab tes xis, thaum rub txoj hlua nrog tus ntiv tes nruab nrab, tom qab ntawd koj yuav tsum tam sim ntawd tso tus ntiv tes taw thiab tso txoj hlua. Thaum ua yeeb yam, koj yuav tsum poob lub suab nrov thiab hnov tsuas yog lub suab nrov. Hauv qhov no, koj tuaj yeem hnov ib qho kev sib raug zoo sib xws.

Artificial harmonics kuj tau tso tawm hauv daim ntawv suab paj nruag hauv daim ntawv rhombus, thiab nws tau qhia rau qhov kev ntxhov siab uas yuav tsum tau ua si. Nws yog qhov yooj yim tshwj xeeb los ua cov txheej txheem no ntawm lub tshuab hluav taws xob guitar. Xws li ib tug harmonic yog qhia nyob rau hauv lub tablature los ntawm peb sau ntawv: lub qis ib qhia tau hais tias nyob rau hauv lub sab laug tes ntawm tus guitarist yuav tsum tau, nws kuj txiav txim siab lub sij hawm ntawm lub suab, lub nruab nrab daim ntawv qhia qhov twg tus ntiv tes ntawm sab tes xis yuav tsum tau kov. txoj hlua (pob zeb diamond-zoo li tus), thiab lub sab sauv qhia tau hais tias lub harmonic nws tus kheej (peb hnov). Nyob rau hauv daim ntawv suab paj nruag, sau complex harmonics zoo ib yam li kev sau ntawv.

Mediator extraction method

Txoj haujlwm ntawm no yog tib yam li yav dhau los. Koj yuav tsum tuav lub fret ntawm txoj hlua, ces rub nws thiab tam sim ntawd kov nws kom zoo li poob lub suab. Qhov no yuav tsum tau ua nrog tus ntiv tes xoo lossis tus ntiv tes xoo, nrog rau ib feem ntawm nws. Nrog rau txoj kev no, nws yog ib qho tseem ceeb tsis tsuas yog kom paub thiab muaj peev xwm ua tau raws li cov txheej txheem ntawm ib tug dag flageolet, tab sis kuj yuav tsum tuav tus neeg nruab nrab kom raug, uas yog, yuav tsum muaj qhov tseeb ntawm tes. Raws li txoj cai, nws yog nyob rau hauv no txoj kev uasHarmonica musicians ntaus guitar.

Ntiv tes rho tawm txoj kev

Thaum ua si nrog brute force, txoj kev dhau los yuav tsis ua haujlwm. Cov txheej txheem no yog qhov nyuaj dua, nws yog ib qho tseem ceeb kom nrhiav tau ib txoj hauj lwm zoo ntawm cov ntiv tes thiab nqa cov flageolet tua mechanism rau automatism.

Zoo kawg

Kev txais tos ntawm kev sib haum xeeb yog qhov nyuaj heev thiab, zoo li txhua yam kev ua suab paj nruag, nws yuav tsum tau siv sijhawm ntau, saib xyuas los ntawm tus kws ua yeeb yam thiab kev cob qhia. Ntxiv nrog rau lub guitar, kev sib raug zoo tau siv zog rau ntawm cov hlua khi hlua, qhov twg lawv tuaj yeem nqa nrog hneev nti, thiab lawv lub suab sib txawv kiag li. Yog tias ua tau, nws raug nquahu kom paub cov txheej txheem no raws li kev qhia ntawm tus kws qhia ntawv tshwj xeeb, yog li cov txheej txheem yuav mus nrawm dua thiab ua tau zoo dua.

Kev muaj peev xwm ua cov txheej txheem no yuav ntxiv kev ntseeg siab rau txhua tus kws ntaus nkauj, thiab nws tuaj yeem siv yuav luag txhua yam. Qhov no yuav tso cai rau koj tsom mus rau koj qhov kev ua tau zoo hauv ntau qhov chaw hauv txhua qhov kev npaj.
