Inversion ntawm triads: yuav ua li cas inversions tshwm sim, hom inversions, lawv tsim li cas?

Triad inversion yog ib qho kev hloov pauv hauv cov qauv qub ntawm chord nyob rau hauv uas ib qho tshiab chord yog tsim los ntawm tib lub suab. Tsis tsuas yog triads tuaj yeem hais txog (ib lub chord ntawm peb lub suab), tab sis kuj muaj lwm yam chords, nrog rau lub sijhawm.

Lub hauv paus ntsiab lus ntawm inversion (los yog, yog tias koj nyiam, kev sib hloov ib ncig) yog tib yam nyob rau hauv txhua rooj plaub: tag nrho cov suab uas nyob rau hauv ib tug muab thawj chord nyob twj ywm nyob rau hauv lawv qhov chaw tsuas yog ib tug - sab sauv los yog qis. Lub suab sab saud lossis qis dua yog lub xov tooj ntawm tes, nws txav: sab saud ib qho octave, thiab qis dua, ntawm qhov tsis sib xws, nce ib qho octave.

Raws li koj tuaj yeem pom, cov txheej txheem rau kev ua chord inversion yog qhov yooj yim tshaj plaws. Tab sis peb feem ntau txaus siab rau qhov tshwm sim ntawm inversion ntawm triads. Yog li, raws li qhov tshwm sim ntawm kev ncig, raws li peb tau sau tseg lawm, ib qho tshiab chord raug tsim - nws muaj tib lub suab nkaus xwb, tab sis cov suab no nyob txawv. Uas yog, nyob rau hauv lwm yam lus, tus qauv ntawm chord hloov.

Cia saib ib qho piv txwv:

AC loj triad tau muab (los ntawm lub suab C, E thiab G), qhov triad no muaj, raws li qhov xav tau, ntawm ob feem peb, thiab cov ntawv tshaj tawm ntawm lub chord no tau sib nrug los ntawm ib qho zoo kawg nkaus thib tsib. Tam sim no cia peb ua si ib puag ncig nrog kev thov rov hais dua; Peb tsuas yog yuav tau txais ob ntawm lawv:

1. Peb txav lub suab qis (ua) mus rau octave. Dab tsi tshwm sim? Tag nrho cov suab tseem zoo ib yam (ib yam ua, mi thiab sol), tab sis tam sim no lub chord (mi-sol-do) tsis muaj ob feem peb, tam sim no nws muaj peb (mi-sol) thiab quart (sol - ua). Lub quart (sol-do) tuaj qhov twg? Thiab nws tau los ntawm qhov kev hloov pauv ntawm qhov thib tsib (CG), uas "tso" peb tus thawj C loj triad (raws li txoj cai ntawm inversion ntawm lub sijhawm, thib tsib tig mus rau hauv plaub).
2. Cia peb tig peb qhov "kev puas tsuaj" chord dua: txav nws daim ntawv qis (E) mus rau octave. Qhov tshwm sim yog G-do-mi chord. Nws muaj quart (sol-do) thiab peb (do-mi). Qhov thib plaub tseem nyob ntawm qhov kev hloov pauv yav dhau los, thiab qhov thib peb tshiab tau tsim los ntawm qhov tseeb tias peb tig daim ntawv E ncig ua, raws li qhov tshwm sim ntawm thib rau (mi-do), uas yog tsim los ntawm cov suab nrov ntawm lub chord yav dhau los, tau hloov los ntawm ib feem peb (ua e): raws li cov cai ntawm inversion intervals (thiab tag nrho cov chords, raws li koj paub, muaj qee lub sijhawm), thib rau tig mus rau peb.

Yuav ua li cas yog tias peb sim thim rov qab chord kawg tau txais dua? Tsis muaj dab tsi tshwj xeeb! Peb yuav, tau kawg, txav G qis dua ib qho octave, tab sis vim li ntawd peb yuav tau txais tib lub chord raws li peb tau muaj thaum pib (do-mi-sol). Qhov ntawd yog, yog li ntawd, nws yuav pom tseeb rau peb tias Lub triad tsuas muaj ob inversions, ntxiv kev sim hloov pauv coj peb rov qab mus rau qhov uas peb tawm mus.

Dab tsi yog inversions ntawm triads hu ua?

Thawj hu yog hu sex chord. Cia kuv ceeb toom rau koj tias ib tug thib rau chord yog tsim los ntawm ib tug thib peb thiab ib tug plaub. Lub thib rau chord raug xaiv los ntawm tus lej "6", uas tau ntxiv rau hauv tsab ntawv qhia txog kev ua haujlwm lossis hom chord, lossis rau Roman tus lej, los ntawm qhov peb twv seb qib twg ntawm thawj triad tau tsim. .

Qhov thib ob inversion ntawm triad yog hu ua sib chord, nws cov qauv yog tsim los ntawm plaub thiab ib feem peb. Lub quartsextac chord yog tsim los ntawm tus lej "6" thiab "4". .

Cov triads sib txawv muab qhov sib txawv

Raws li koj tej zaum paub triads - 4 hom: loj (los yog loj), me me (los yog me), nce thiab txo. Cov triads sib txawv muab sib txawv inversions (uas yog, lawv yog tib lub thib rau chords thiab lub quarter sib deev chords, tsuas yog me me tab sis tseem ceeb hloov hauv cov qauv). Tau kawg, qhov sib txawv no tau tshwm sim hauv lub suab ntawm chord.

Kom nkag siab txog qhov sib txawv ntawm cov qauv, cia peb saib ib qho piv txwv dua. Ntawm no 4 hom triads los ntawm daim ntawv "D" yuav raug tsim thiab rau txhua ntawm plaub triads lawv inversions yuav raug sau tawm:

******************************************************** ***************************

Lub triad loj (B53) muaj ob feem peb: ib qho loj (D thiab F ntse), qhov thib ob me (F ntse thiab A). Nws thib rau chord (B6) muaj ib tug me thib peb (F-sharp A) thiab ib tug zoo meej plaub (AD), thiab ib lub quarter-poj niam chord (B64) muaj ib tug zoo meej plaub ( tib AD) thiab ib tug loj thib peb (D. thiab F-sharp).

******************************************************** ***************************

Lub triad me (M53) kuj tsim los ntawm ob feem peb, tsuas yog thawj zaug yuav yog me (re-fa), thiab qhov thib ob yuav loj (fa-la). Lub thib rau chord (M6), raws li, pib nrog ib tug loj thib peb (FA), uas yog ces koom nrog ib tug zoo meej plaub (AD). Cov me me quartet-sex chord (M64) muaj ib qho zoo meej quartet (AD) thiab me thib peb (DF).

******************************************************** ***************************

Ib qho augmented triad (Uv53) yog tau los ntawm kev ntxiv ob feem peb (1st - D thiab F-sharp; 2nd - F-sharp thiab A-sharp), ib tug thib rau chord (Uv6) yog tsim los ntawm ib tug loj thib peb (F-ntse). thiab A-sharp ) thiab diminished thib plaub (A-ntse thiab D). Tom ntej no inversion yog ib qho ntxiv quartersex chord (Uv64) qhov twg plaub thiab thib peb yog swapped. Nws yog xav paub tias tag nrho cov inversions ntawm augmented triad, vim lawv muaj pes tsawg leeg, kuj zoo li augmented triads.

******************************************************** ***************************

Lub triad ploj (Um53) muaj, raws li koj twv, ntawm ob feem peb (DF - 1st; thiab F nrog A-flat - 2nd). Ib qho kev poob rau thib rau chord (Um6) yog tsim los ntawm ib qho me me thib peb (F thiab A-flat) thiab qhov thib plaub (A-flat thiab D). Thaum kawg, lub quartet-poj niam txiv chord ntawm no triad (Uv64) pib nrog ib tug augmented plaub (A-flat thiab D), saum toj no uas ib tug me thib peb (DF) yog tsim.

Cia peb xaus peb qhov kev xyaum ua tau zoo hauv ntau cov qauv:

Nws puas tuaj yeem tsim cov lus thov los ntawm lub suab?

Yog lawm, paub txog cov qauv ntawm txhua qhov kev hloov pauv, koj tuaj yeem yooj yim tsim tag nrho cov chords uas koj tau kawm txog hnub no los ntawm ib lub suab. Piv txwv li, cia peb tsim los ntawm mi (tsis muaj lus pom):

Txhua tus! Ua tsaug rau koj mloog! Hmoov zoo!
