Cov npe ntawm cov suab muaj nyob rau hauv xya chord (hauv ib qho, tsis tas yuav yog ib qho loj) qhia cov npe ntawm lub sijhawm los ntawm lub suab qis tshaj mus rau ib qho hauv qab no:

• Prima. Qhov no yog lub suab qis tshaj, lub hauv paus ntawm chord.
• Peb. Ob lub suab ntawm hauv qab. Nruab nrab ntawm lub suab no thiab lub prima yog lub caij nyoog "thib peb".
• Quint. Lub suab thib peb ntawm hauv qab. Los ntawm prima mus rau lub suab no - lub sij hawm ntawm "thib tsib".
• Xya. Upper suab (sab saum toj ntawm chord). Nruab nrab ntawm lub suab no thiab lub hauv paus ntawm chord yog lub sij hawm xya.

Nyob ntawm seb hom triad uas yog ib feem ntawm chord, loj xya chords tau muab faib ua peb hom:

1. Grand Major xyab chord

Cia peb xav txog txhua yam sib cais.

Grand Major xyab chord

Loj xya chord inversions

Lub inversion ntawm xya chord yog tsim los ntawm kev txav cov ntawv qis mus rau ib qho octave (raws li nrog txhua chords). Lub npe ntawm lub suab hloov pauv tsis hloov pauv, piv txwv li yog tias qhov lees txais tau txav mus rau ib qho octave, nws yuav nyob twj ywm prima (nws yuav tsis yog "thib tsib", txawm hais tias nws yuav yog saum toj ntawm lub chord tshiab).

Lub xya chord muaj peb inversions (cov npe ntawm nws cov inversions yog raws li lub caij nyoog muaj nyob rau hauv inversions):

Thawj qhov kev thov rov hais dua. Quintsextachord.

Txhais tau tias ( ⁶ / ₅ ). Nws yog tsim los ntawm kev hloov ntawm prima mus rau octave:

Daim duab 4. Kev tsim kho ntawm thawj inversion ntawm ib tug loj xya chord

Saib daim duab. Thawj qhov ntsuas qhia qhov loj thib xya chord (kos hauv grey), thiab qhov ntsuas thib ob qhia nws thawj qhov kev hloov pauv. Lub xub liab qhia qhov hloov ntawm lub prima mus rau ib qho octave.

Qhov kev thov rov hais dua thib ob. Terzkvartakkord

Txhais tau tias ( ⁴ / ₃ ). Nws yog tsim los ntawm kev hloov ntawm prima thiab thib peb los ntawm octave li (los yog qhov thib peb ntawm thawj inversion, uas yog qhia nyob rau hauv daim duab):

Daim duab 5. Kev xaiv kom tau txais terzquartaccord (2nd reversal)

Thawj bar qhia qhov loj xya chord, qhov thib ob bar qhia nws thawj inversion, thiab peb bar qhia nws thib ob inversion. Sequentially hloov lub suab qis mus rau octave, peb tau txais lub quarter thib peb chord.

Kev thov thib peb. Thib ob chord.

Denoted los ntawm (2). Nws yog tsim raws li ib tug tshwm sim ntawm kev hloov ntawm lub prima, peb thiab tsib ntawm lub xya chord li ib octave. Daim duab qhia txog cov txheej txheem ntawm kev tsim tag nrho peb inversions ntawm lub loj loj xya chord C ^{hloov 7} :

Daim duab 6. Cov txheej txheem ntawm kev txais tag nrho peb daim ntawv thov ntawm lub xya chord yog piav qhia.

Nyob rau hauv thawj qhov kev ntsuas, ib tug loj xya chord yog depicted, nyob rau hauv lub thib ob - nws thawj inversion, nyob rau hauv peb ntsuas - nws thib ob inversion, nyob rau hauv lub plaub - lub thib peb inversion. Sequentially hloov lub suab qis mus rau octave, peb tau txais tag nrho cov inversions ntawm xya chord.
