Juyawar triads: ta yaya ƙetare ke tasowa, nau'ikan juzu'i, ta yaya aka gina su?

Juyawa Triad canji ne a cikin ainihin tsarin ƙwanƙwasa wanda a cikinsa aka samar da sabon maƙalli mai alaƙa daga sauti iri ɗaya. Ba wai kawai triads za a iya magance su ba (Ma'auni na sautuka uku), amma kuma kowane nau'i, da kuma tazara.

Ka'idar jujjuyawar (ko, idan kun fi so, jujjuyawa a kusa) iri ɗaya ne a kowane yanayi: duk sautunan da ke cikin ƙa'idar da aka bayar na asali sun kasance a wurarensu sai ɗaya - babba ko ƙasa. Wannan sautin na sama ko na ƙasa yana motsi, yana motsawa: na sama yana ƙasa da octave, na ƙasa kuma, akasin haka, sama da octave.

Kamar yadda kake gani, dabarar yin juzu'i ita ce mafi sauƙi. Amma mu ne yafi sha'awar sakamakon inversion na triads. Don haka, a sakamakon zagayawa, kamar yadda muka riga muka lura, an kafa wani sabon nau'i mai alaƙa - ya ƙunshi sauti iri ɗaya, amma waɗannan sautunan suna wurin daban. Wato, a wasu kalmomi, tsarin maɗaukaki yana canzawa.

Bari mu dubi misali:

An ba da babban triad AC (daga sautunan C, E da G), wannan triad ɗin ya ƙunshi, kamar yadda ake tsammani, na kashi biyu cikin uku, kuma an raba matsananciyar bayanan wannan maƙallan daga juna ta hanyar cikakken na biyar. Yanzu bari mu yi wasa tare da roko; za mu samu guda biyu ne kawai:

1. Mun matsar da ƙananan sauti (yi) sama da octave. Me ya faru? Duk sautunan sun kasance iri ɗaya ne (do ɗaya suke yi, mi da sol), amma yanzu maƙarƙashiyar (mi-sol-do) ba ta ƙunshi kashi biyu cikin uku ba, yanzu ta ƙunshi kashi na uku (mi-sol) da quart (sol). - yi). Daga ina quart (sol-do) ya fito? Kuma ya zo ne daga jujjuyawar wancan na biyar (CG), wanda “ya ruguje” babban triad ɗinmu na asali na C (bisa ga ka’idar jujjuya tazara, kashi biyar sun koma kashi huɗu).
2. Bari mu sake jujjuya wakokinmu na “lalacewa”: matsar da ƙaramin bayanin sa (E) sama da octave. Sakamakon shine G-do-mi chord. Ya ƙunshi quart (sol-do) da na uku (do-mi). Na huɗu ya kasance daga jujjuyawar da ta gabata, kuma sabon na uku an gina shi ne daga gaskiyar cewa mun juya bayanin kula E a kusa da yi, sakamakon na shida (mi-do), wanda ya ƙunshi matsananciyar sauti na maɗaukakin baya. an maye gurbinsu da na uku (do e): bisa ga ka'idodin tazarar juzu'i (kuma duk maƙallan, kamar yadda kuka sani, sun ƙunshi wasu tazara), kashi shida sun juya zuwa kashi uku.

Menene zai faru idan muka yi ƙoƙari mu sake jujjuya waƙar da aka samu ta ƙarshe? Babu wani abu na musamman! Za mu, ba shakka, matsar da ƙananan G zuwa octave, amma a sakamakon haka za mu sami irin wannan ma'anar kamar yadda muka samu a farkon (do-mi-sol). Wato, ta haka, ya bayyana a gare mu cewa Triad yana da juzu'i biyu kawai, ƙarin yunƙurin tuba ya kai mu zuwa inda muka bari.

Menene ake kira jujjuyawar triads?

Ana kiran kiran farko jima'i jima'i. Bari in tunatar da ku cewa maɗaukaki na shida yana da na uku da na huɗu. An tsara maƙala ta shida ta lamba “6”, wadda aka ƙara a cikin wasiƙar da ke nuna aiki ko nau’in maɗaukaki, ko kuma zuwa lamba ta Romawa, ta inda muke tsammani a wane mataki aka gina ainihin triad. .

Ana kiran juyawa na biyu na triad kwata-kwata, tsarinsa yana samuwa ta huɗu da na uku. An tsara maƙallan quartsextac ta lambobi "6" da "4". .
