Izikhawu zesici ze-harmonic ezinkulu nezincane ze-harmonic

Izikhawu zesici zivela kuphela ku-harmonic enkulu kanye ne-harmonic encane.

Kunezikhawu ezine zesici kuphela, lawa amapheya amabili ezikhathi ezixhumene ezikhulisiwe nezinciphile:

• okwesibili okungeziwe futhi kwehle okwesikhombisa (uv. 2 nengqondo.7);
• i-augmented yesihlanu yancipha yesine (uv.5 kanye um.4).

Njengengxenye yezikhawu zesici ngasinye kufanele kube nesinyathelo esiyisici, okungukuthi, isinyathelo esishintshayo ngenxa yokuthi imodi iba yi-harmonic. Kokukhulu, lesi yisinyathelo esiphansi sesithupha, kanti kwabancane, lesi sinyathelo singesesikhombisa esanda. Isinyathelo sesici kungaba umsindo ophansi wesikhawu sesici noma ongaphezulu.

Ngokuvamile, izigaba VI, VII, no-III zibamba iqhaza ekwakhiweni kwezikhawu zesici.

Uma ufuna izikhawu zesici kukhiye, qaphela okulandelayo:

• Ku-harmonic enkulu, isici esikhulisiwe (sw.2 kanye ne-sv.5) sakhelwe ku-VI eyehlisiwe, futhi ungathola abalingani babo (d.7 kanye no-w.4) ngokumane uguqule;
• Ku-harmonic encane, kulula ukuthola izici ezinciphile (min.7 kanye ne-min.4), zakhiwe ngesinyathelo esiphakanyisiwe se-VII, abalingani babo (sw.2 kanye ne-w.5) batholakala ngendlela yokuguqula.

Izinyathelo okwakhiwe kuzo zonke izikhawu zesici kulula ukuzikhumbula. Ukuze kube lula, ungasebenzisa ithebula elilandelayo:

Izikhawu zesici azinzile, ngakho-ke kufanele zixazululwe. Imvume yenziwa ngokuya ngezimiso ezifanayo ezisetshenziswe kuma-tritons:

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

Umphumela wokulungiswa kwezikhawu zesici uhlala uzinzile:

• i-uv.2 ivunyelwe engxenyeni yesi-4
• ingqondo.7 ivunyelwe engxenyeni 5
• sw.5 kuvunyelwe ku-b.6
• um.4 kuvunyelwe ku-m.3

Isici sokulungiswa kwe-SW.5 ne-SW.4 yi isixazululo sendlela eyodwa: isinyathelo III sifakiwe kulezi zikhathi, futhi lapho sixazululwa, sihlala sisendaweni, njengoba sizinzile (okungukuthi, asidingi imvume).

Isibonelo sokuxazulula izikhawu zesici kukhiye we-C enkulu:
