Cov yam ntxwv sib txawv ntawm harmonic loj thiab harmonic minor

Cov yam ntxwv ncua sij hawm tsuas yog tshwm sim nyob rau hauv harmonic loj thiab harmonic me.

Tsuas muaj plaub lub sijhawm sib txawv, cov no yog ob khub ntawm kev sib cuam tshuam nce thiab txo qis:

• augmented thib ob thiab diminished thib xya (ua uv. 2a xav 7);
• augmented thib tsib thiab diminished thib plaub (ua 5u4).

Raws li ib feem ntawm txhua tus yam ntxwv ncua sij hawm yuav tsum muaj tus yam ntxwv theem, uas yog, ib kauj ruam uas hloov vim lub fact tias hom yuav harmonic. Rau qhov loj, qhov no yog qib thib rau qis, thiab rau cov menyuam yaus, cov kauj ruam no yog thib xya nce. Cov yam ntxwv theem yog ob lub suab qis ntawm cov yam ntxwv ncua sij hawm los yog sab saud.

Feem ntau, theem VI, VII, thiab III koom nrog hauv kev tsim cov yam ntxwv sib txawv.

Thaum nrhiav cov yam ntxwv ncua sij hawm hauv ib qho tseem ceeb, ua tib zoo saib cov hauv qab no:

• Hauv kev sib haum xeeb loj, cov yam ntxwv nce ntxiv (sw.2 thiab sv.5) yog tsim los ntawm qis VI, thiab koj tuaj yeem pom lawv cov neeg koom tes (d.7 thiab w.4) yooj yim los ntawm kev hloov pauv;
• Hauv kev sib haum xeeb me me, nws yooj yim dua los nrhiav cov yam ntxwv uas ploj zuj zus (min.7 thiab min.4), lawv tau tsim los ntawm VII tsa cov kauj ruam, lawv cov neeg koom tes (sw.2 thiab w.5) tau txais los ntawm txoj kev inversion.

Cov kauj ruam ntawm txhua qhov sib txawv ntawm cov yam ntxwv tsim tau yooj yim rau kev nco qab. Txhawm rau kom yooj yim, koj tuaj yeem siv cov lus hauv qab no:

Cov yam ntxwv ncua sij hawm tsis ruaj khov, yog li lawv yuav tsum tau daws. Kev tso cai yog ua raws li tib lub hauv paus ntsiab lus uas tau siv rau tritons:

• 1) raws li kev daws teeb meem, lub suab tsis ruaj khov yuav tsum tig mus rau qhov ruaj khov (uas yog, mus rau hauv lub suab ntawm tonic triad);
• 2) txo qhov ncua sij hawm txo qis (nqaim), cov ntu loj zuj zus ntxiv (nrawm).

Qhov tshwm sim ntawm kev daws teeb meem ntawm cov yam ntxwv ncua sij hawm yog ib txwm ruaj khov:

• uv.2 tso cai rau part 4
• mind.7 tso cai part 5
• sw.5 tso cai rau hauv b.6
• um.4 tso cai rau hauv m.3

Ib tug feature ntawm kev daws teeb meem ntawm SW.5 thiab SW.4 yog ib txoj kev daws teeb meem: Kauj Ruam III suav nrog hauv cov ntu no, thiab thaum nws daws tau, nws tsuas yog nyob hauv qhov chaw, vim nws ruaj khov (uas yog, nws tsis tas yuav tsum tau tso cai).

Ib qho piv txwv ntawm kev daws cov yam ntxwv ncua sij hawm hauv qhov tseem ceeb ntawm C loj:
