ʻO Octave ma ka piano

Kapa ʻia ka wā ma waena o nā memo like ʻelua he octave . No ka hoʻoholo ʻana i kekahi o lākou, ua lawa ka loaʻa ʻana o ka memo "hana" ma ka papa keyboard a, e neʻe i luna a i lalo i nā kī keʻokeʻo, helu ʻewalu mau ʻāpana, a hiki i ka memo aʻe o ka inoa like.

Mai ka Latin, ka huaʻōlelo " octave ua unuhi ʻia ʻo "ʻewalu". Hoʻokaʻawale kēia mau ʻanuʻu ʻewalu i nā memo o ʻelua octaves mai kekahi i kekahi, e hoʻoholo ana i ko lākou alapine - ka wikiwiki o ka oscillation. No ka laʻana, ka alapine (frequency) o ka memo "la" hookahi octave he 440 Hz , A me ka alapine (frequency) ʻO ka helu like he 880 ka octave ma luna Hz . Ke alapine (frequency) ʻO nā memo he 2: 1 - ʻo kēia ratio ka mea ʻoluʻolu loa e hoʻolohe. He 9 octaves ka piano maʻamau, no ka mea, ʻekolu mau memo o ka subcontroctave a ʻo ka hapalima he hoʻokahi.

ʻO Octave ma ka piano

ʻO nā ʻokoʻa ma waena o nā memo like ʻole o nā alapine like ʻole he octaves ma ka piano. Hoʻonohonoho ʻia lākou i loko ka He helu like a like me ka papa piano. Eia ka nui o na octaves ma ka piano.

1. Subcontroctave - he ʻekolu mau memo.
2. ʻaelike.
3. Nui.
4. Liʻiliʻi.
5. Ka mua.
6. Tue uē ʻana.
7. Ke kolu.
8. Ka 'ehā.
9. ʻElima - hoʻokahi memo.

ʻO nā memo o ka subcontroctave he mau leo ​​haʻahaʻa loa, ʻo ka lima ka leo hoʻokahi i ʻoi aku ka kiʻekiʻe ma mua o ke koena. I ka hoʻomaʻamaʻa ʻana, pono ʻole ka pāʻani ʻana i kēia mau memo. ʻO nā memo i hoʻohana nui ʻia mai ka nui a hiki i ke kolu octave.

Ina he nui na au o ka piano e like me na octaves ma ka piano, alaila na octaves ma ka piano. mea hoʻohui ʻokoʻa ka helu mai nā mea kani i hōʻike ʻia. ʻO kēia ma muli o ka ʻoiaʻiʻo o ka mea hoʻohui liʻiliʻi nā kī. Ma mua o ke kūʻai ʻana i kahi mea kani, pono e noʻonoʻo i ka hiʻohiʻona.

Nā ʻoka liʻiliʻi a me ka mua

ʻO kekahi o nā octaves maʻamau i hoʻohana ʻia ʻo ia nā octaves liʻiliʻi a mua o ka piano a i ʻole pianoforte. ʻO ka mua octave Aia ma ka piano ma ke kikowaena, ʻoiai ʻo ia ka lima o ka lālani, a ʻo ka mua he subcontroctave. Loaʻa iā ia nā memo o ke kiʻekiʻe waena mai 261.63 a 523.25 Hz , hōʻike ʻia e nā hōʻailona C4-B4. Aia nā memo ma lalo o ke kani octave liʻiliʻi haʻahaʻa me ke alapine o 130.81 a 261.63. Hz .

Nā memo o ka octave mua

Hoʻopiha nā memo o ka octave mua i nā laina mua ʻekolu o nā ʻauamo o ka clef treble. Ua kakauia na hoailona o ka octave mua penei:

1. TO – ma ka laina hou mua.
2. PE - ma lalo o ka laina nui mua.
3. MI - hoʻopiha i ka laina mua.
4. FA - ua kākauʻia ma waena o ka mua a me ka ka lua laina.
5. PAʻakai - ma ka ka lua mea hoʻoiho.
6. LA - ma waena o ke kolu a me ka lua laina.
7. SI - ma ka laina ʻekolu.

ʻOi a me nā pālahalaha

ʻO ka hoʻonohonoho ʻana o nā octaves ma ka piano a me ka piano ʻaʻole wale ke keʻokeʻo akā ʻeleʻele pū kekahi. Inā hōʻike ka papa keyboard keʻokeʻo i nā leo nui - nā leo, a laila ʻo ka ʻeleʻele - ko lākou hoʻokiʻekiʻe a hoʻohaʻahaʻa ʻia paha - semitones. Ma waho aʻe o ke keʻokeʻo, ka mua octave aia nā kī ʻeleʻele: C-sharp, RE-sharp, FA-sharp, G-sharp, A-sharp. Ma ka helu mele, ua kapa ʻia lākou he accidental. No ka pāʻani ʻana i nā koi, pono ʻoe e kaomi i nā kī ʻeleʻele. ʻO nā ʻokoʻa wale nō ʻo MI-sharp a me SI-sharp: hoʻokani ʻia lākou ma nā kī keʻokeʻo FA a me DO o ka octave aʻe.

No ka pāʻani pālahalaha, pono ʻoe e kaomi i nā kī ma ka ʻaoʻao hema - hāʻawi lākou i kahi kani i kahi semitone haʻahaʻa. No ka laʻana, hoʻokani ʻia ka D flat ma nā kī ma ka hema o ka D keʻokeʻo.

Pehea e pāʻani pono ai i nā octaves

Ma hope o ka hoʻomaʻamaʻa ʻana o ka mea hoʻokani i ka inoa o nā octave ma ka piano, pono ke pāʻani i nā unahi - nā ʻano o nā memo o hoʻokahi octave. No ke aʻo ʻana, ʻoi aku ka maikaʻi o C major. Pono e hoʻomaka me ka lima hoʻokahi, me ka mālie a me ke kau ʻana o nā manamana lima ma ka papa keyboard. No ke aʻo ʻana pehea e hana ai i kēia, hiki iā ʻoe ke hoʻoiho i ka haʻawina. Ke pāʻani i ka pālākiō me ka lima hoʻokahi e hilinaʻi a maopopo, pono e hana like me ka ka lua lima.

Nui nā unahi e like me nā octaves piha - 7. Hoʻokani kaʻawale ʻia lākou me ka lima hoʻokahi a ʻelua paha. I ka ulu ʻana o ke akamai, pono e hoʻonui ka wikiwiki i maʻa nā lima lima i ke kikoo. He mea nui e aʻo pehea e hoʻololi ai i ke kaumaha mai kou mau lima i nā kī, e mālama i kou poʻohiwi me ka manuahi. ʻOi aku ka lōʻihi o nā manamana lima a me nā pulima lima, e maʻa i nā manawa.

Inā pāʻani mau ʻoe i nā unahi, ʻo ka manaʻo o \u200b\ Hoʻopanee ʻia ʻo u200boctaves i ka noʻonoʻo, a e neʻe wikiwiki nā lima ma luna o lākou i kēlā me kēia manawa.

Nā Kuleana Rookie

Ke hoʻomaka nei nā mea hoʻokani pila i kēia mau hewa:

1. ʻAʻohe o lākou manaʻo maʻamau e pili ana i ka mea hana, kāna mea hana.
2. ʻAʻole maopopo iā lākou ka nui o nā octaves ma ka piano, ʻo ia ka mea i kapa ʻia.
3. Hoʻopaʻa ʻia lākou i ka octave mua a i ʻole hoʻomaka lākou i ka unahi wale nō mai ka memo DO, me ka hoʻololi ʻole ʻana i nā octave a me nā memo ʻē aʻe.

ʻO wai ka mea ʻoi aku ka maikaʻi o ka pāʻani ʻana i ka octave: me ka lima holoʻokoʻa a i ʻole me ka paʻi ʻana o ka pulupulu?

Pono e pāʻani ʻia nā octaves māmā me ka hoʻohana ikaika ʻana o ka lima, e kau ana i ka lima haʻahaʻa, ʻoiai e pāʻani ʻia nā octaves paʻakikī me ka hoʻokiʻekiʻe ʻana o ka lima.

Pehea e pāʻani wikiwiki ai i nā octaves?

Pono ka lima a me ka lima e hoʻopaʻa iki. Ke ʻike koke ʻia ka luhi, pono e hoʻololi ʻia ke kūlana mai ka haʻahaʻa a i ke kiʻekiʻe a me ka hope.

Loaʻa i luna

ʻO ka huina o nā octaves ma kahi piano, piano a piano nui paha, he 9, nona ka piha o 7 octaves, he ʻewalu mau memo. Ma ka he mea hookui , pili ka helu octave i ka helu o nā memo a ʻokoʻa paha me nā mea kani kahiko. ʻO ka pinepine, liʻiliʻi, mua a me ka lua ʻokekota hoʻohana ʻia, kakaʻikahi loa - subcontroctave a me ka lima octave . No ka haku octaves, pono e pāʻani kekahi i nā unahi, e hoʻomaka me ka mālie ke kino , me ka lima hoʻokahi a me ke kau pololei ʻana o nā manamana lima.
