Hoʻohana: kūpono no ka mining, ʻoihana kemika, ka mahiʻai, ka mālama ʻana i ke kaiapuni a me ke kūkulu ʻana i ka ʻenekinia kumu pile a me nā ʻoihana ʻē aʻe.
No ke anawaena nui, ka mānoanoa nui, nā kiko'ī kūikawā a me nā mea pale lole, ke kila kila.
Ua aneane like ka mānoanoa o waho a me ka mānoanoa o loko. Ma hope o ka hana ʻana i ke anawaena o loko, hiki i ke anawaena o waho a me ka pitch ke hoʻokō pololei i ka nui i makemake ʻia.
ʻO ke anawaena like a me ka pitch, ka pitch hiki ke hoʻololi ʻia, a me ka pōʻai puka a me ke anawaena me nā ʻano like ʻole o ka convex a i ʻole nā koi āpau.
ʻO ka hoʻokumu ʻana i ka pololei maikaʻi, ka helu kiʻekiʻe kiʻekiʻe o nā huahana i hoʻopau ʻia, nā pūʻulu liʻiliʻi, hiki ke hoʻokō i nā pono lako pilikino, kūpono loa no ka nui nui, ka mānoanoa nui a me ke kapa kila kūpaʻa, nā mea kila kuhili ʻole o ka hana ʻana o ka lau spiral.
