Subdominant |
Subdominant (los ntawm Latin sub - hauv qab thiab tseem ceeb; Fabkis sousdominante, German Subdominante, Unterdominante) - lub npe ntawm IV degree ntawm qhov ntsuas; nyob rau hauv cov lus qhuab qhia ntawm kev sib haum xeeb kuj hu ua. chords ua rau ntawm cov kauj ruam no, thiab muaj nuj nqi uas ua ke chords IV, II, qis II, VI kauj ruam. C. yog txhais los ntawm tsab ntawv S (lub cim no, zoo li D thiab T, tau thov los ntawm X. Riemann). Tus nqi ntawm S. chords nyob rau hauv lub tonal-functional system ntawm kev sib haum xeeb yog txiav txim los ntawm qhov xwm ntawm lawv kev sib raug zoo rau lub tonic chord (T). Main S. lub suab tsis muaj nyob rau hauv tej tonic. triads, los yog nyob rau hauv lub overtone series los ntawm lub tonic. suab nrov. Lub suab nrov T yog ib feem ntawm C. chord thiab nyob rau hauv lub overtone-tshiab series los ntawm IV degree ntawm lub teev. Raws li Riemann, kev txav ntawm kev sib haum xeeb (los ntawm T) mus rau C. triad zoo ib yam li kev hloov pauv hauv nruab nrab ntawm lub ntiajteb txawj nqus (yog li ntawd, C. gravitates tsawg sharply nyob rau hauv T tshaj D), uas yuav tsum tau ntxiv dag zog rau qhov tonality; yog li kev nkag siab ntawm S. raws li "chord ntawm kev tsis sib haum xeeb" (Riemann). Cov lus qhia tom ntej ntawm D chord rov ua kom lub ntsej muag zoo nkauj rau T thiab yog li ntxiv dag zog rau tonality. Lub turnover S - T, uas tsis muaj lub cim ntawm ib tug rov qab los ntawm lub derived keeb mus rau lub generating element, tsis muaj xws li ib tug muaj zog kev nkag siab ntawm tag nrho cov harmonics. kev loj hlob, "kev ua tiav", raws li kev hloov pauv D - T (saib Plagal cadenza). Lub tswv yim ntawm S. thiab cov ntsiab lus sib raug tau hais los ntawm JF Rameau ("The New System of Music Theory", 1726, ch. 7), uas txhais S, D thiab T ua peb lub hauv paus ntawm hom (hom): " peb lub suab tseem ceeb, to-rye tsim kev sib haum xeeb, uas lawv pom qhov pib ntawm kev ua haujlwm ntawm kev sib haum xeeb. tonality.
