Ma ke mele, he triad kahi pūʻulu o ʻekolu mau memo i hiki ke hoʻopaʻa ʻia i ke kolu. Ua hoʻokumu ʻia ka huaʻōlelo "harmonic triad" e Johannes Lippius ma kāna "Synopsis musicae novae" (1612).
Ke hoʻopaʻa ʻia i ka hapakolu, ua kapa ʻia nā lālā o ka triad, mai ka leo haʻahaʻa a hiki i ke kiʻekiʻe, ʻo ka Root the Third – kona wā mawaena ma luna o ke kumu he hapakolu liʻiliʻi (ʻekolu semitones) a i ʻole ke kolu nui (ʻehā semitones) ʻo ka ʻelima - ʻo kona wā ma luna o ke kolu he hapakolu liʻiliʻi a i ʻole ke kolu nui, no laila ʻo kona wā ma luna o ke kumu he hapalima i emi iho (ʻeono semitones) , ʻelima kūpono (ʻehiku semitones), a i ʻole i hoʻonui ʻia i ka lima (ʻewalu semitones).
Ua kapa ʻia kēlā mau mele he triadic. ʻO kekahi poʻe loea o ka makahiki iwakālua, ʻo ia hoʻi ʻo Howard Hanson lāua ʻo Carlton Gamer, e hoʻonui i ka huaʻōlelo e kuhikuhi i ka hui pū ʻana o ʻekolu mau pitch like ʻole, me ka nānā ʻole i ka wā i waena o lākou.
ʻO ka huaʻōlelo i hoʻohana ʻia e nā mea manaʻo ʻē aʻe no kēia manaʻo maʻamau ʻo "trichord".
ʻO nā mea ʻē aʻe, ʻo ia hoʻi ʻo Allen Forte, hoʻohana i ka huaʻōlelo e kuhikuhi i nā hui ʻana i hoʻopaʻa ʻia i nā wā ʻē aʻe, e like me ka "quartal triad".Forte, Allen, (1973) The Structure of Atonal Music (New Haven and London: Yale University Press): ISBN 0-300-02120-8 I ka hopena o ka Renaissance, ua neʻe ke mele o ke komohana mai ka ʻaoʻao contrapuntal "horizontal" a i ka holomua chord e koi ana i kahi ala "vertical", no laila e hilinaʻi nui ana i ka triad ma ke ʻano he kahua kūkulu kumu o ka lokahi hana. .
Ka leo kumu o ka triad, me ke degere o ka Pāku'i e pili ana, e hoʻoholo mua i ka hana o ka triad i hāʻawi ʻia.
ʻO ka lua, hoʻoholo ʻia ka hana o kahi triad e kona ʻano: nui, liʻiliʻi, hoʻemi a hoʻonui ʻia. ʻEkolu o kēia mau ʻano triad ʻehā i loaʻa i ka pālākiō Major (a i ʻole diatonic).
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu iā Neaera a me kahi mea kūʻai aku ʻike, makuakāne, a makemake hoʻi e hoʻāʻo i nā mea hana hou me ka guitar ma ka puʻuwai o koʻu makemake, a me kaʻu hui, ua hana wau i nā ʻatikala blog hohonu mai 2020 e kōkua i ka poʻe heluhelu kūpaʻa me nā ʻōlelo aʻoaʻo hoʻopaʻa leo a me nā kīkā.
