I-Tritons yezinhlobo zemvelo ne-harmonic ezinkulu nezincane

I-Tritons ihlanganisa izikhawu ezimbili - isihlanu esinciphile (dim. 5) kanye nesine esinyukile (v.4). Inani labo lekhwalithi lingamathoni amathathu aphelele, futhi ayalingana ne-enharmonic (okungukuthi, azwakala afanayo, naphezu kokubhalwa okuhlukile negama).

Lezi izikhawu ezibhanqiwe, njengoba i-uv.4 ingukuguqulwa kwengqondo.5 futhi ngokuphambene nalokho, okungukuthi, aziguquki ngokulinganayo. Uma uphakamisa umsindo ophansi womqondo nge-octave. 5, bese ushiya umsindo wesibili endaweni, uthola SW. 4 futhi ngokuphambene.

Ku-tonality ngaphansi kwezimo ze-diatonic, sidinga ukukwazi ukuthola ama-newts ama-4 kuphela: okubili kwehle kwesihlanu futhi ngokufanayo, amaquart amabili akhulisiwe. Okungukuthi, amapheya amabili ka-um.5 kanye ne-uv.4, ipheya eyodwa yalezi zikhathi ikhona kunkulu yemvelo kanye nencane yemvelo, kanti eyesibili ngaphezu kwalokho ivela ku-harmonic enkulu kanye ne-harmonic encane.

Zakhiwe kuphela ezinyathelweni ezingazinzile - ku-VII, II, IV kanye ne-VI. Kulezi zinyathelo, i-VII ingaphakanyiswa (nge-harmonic minor) futhi i-VI ingahle yehliswe (ngokuyinhloko ye-harmonic).

Ngokuvamile, ama-tritones egameni elikhulu nelincane legama elifanayo ahambisana. Okusho ukuthi, ku-C major kanye no-C minor kuzoba namanewt afanayo ncamashi. Izimvume zabo kuphela ezizohluka.

Ingxenye yesihlanu encishisiwe yakhelwe ezinyathelweni ze-VII ne-II, ikhuphuke okwesine - ku-IV kanye ne-VI.

Imvume tritonov kusekelwe ezimisweni ezimbili:

• 1) lapho isixazululo, imisindo engazinzile kufanele iguquke ibe yizinzile (okungukuthi, imisindo ye-tonic triad);
• 2) izikhawu ezincishisiwe ziyancipha (ezincane), izikhawu ezikhulisiwe ziyakhuphuka (nweba).

Ingxenye yesihlanu encishisiwe ixazululwa ibe ingxenye yesithathu (ngokuxazululwa kwama-tritones emvelo, eyesithathu izoba nkulu, i-harmonic - encane), eyesine eyengeziwe ixazululwa ibe yesithupha (ama-tritones emvelo axazululwa abe yisithupha esincane, kanti i-harmonic - enkulu).

Ngokungeziwe kuma-tritones e-diatonic, mayelana nokuguqulwa kwezinyathelo zomuntu ngamunye, okungeziwe, okuthiwa ama-tritones e-chromatic, kanye nezinye izikhathi ezikhulayo nezinciphile, zingavela ngokuvumelana, sizozihlaziya ngokwehlukana.

I-Tritons izikhawu ezibaluleke kakhulu, njengoba ziyingxenye yezingoma ezimbili eziyinhloko zemodi - i-chord yesikhombisa evelele kanye nesingeniso sekhord yesikhombisa.
