Ama-octaves kupiyano

Isikhawu phakathi kwamanothi amabili afanayo sibizwa i-octave . Ukuze unqume omunye wabo, kwanele ukuthola inothi elithi "yenza" kukhibhodi futhi, ukuhambisa phezulu noma phansi okhiye abamhlophe, ubale izingcezu eziyisishiyagalombili, ufinyelele inothi elilandelayo legama elifanayo.

Kusukela kwisiLatini, igama elithi " octave ” ihunyushwa ngokuthi “yesishiyagalombili”. Lezi zinyathelo eziyisishiyagalombili zihlukanisa amanothi ama-octave amabili komunye nomunye, enquma imvamisa yawo - isivinini se-oscillation. Ngokwesibonelo, i imvamisa yenothi elithi “la” i-octave eyodwa ingu-440 Hz , Kanye imvamisa yenothi elifanayo i-octave ngenhla ingu-880 Hz . Imvamisa kumanothi ngu-2:1 - lesi silinganiso simnandi kakhulu ukusizwa. Ipiyano evamile inama-octave angu-9, uma kubhekwa ukuthi i-subcontroctave inamanothi amathathu kanti eyesihlanu inelilodwa.

Ama-octaves kupiyano

Izikhawu phakathi kwamanothi afanayo amafrikhwensi ahlukene ama-octave ophiyano. Bahlelwe phakathi the inombolo efanayo futhi ngokulandelana okufanayo nasophiyano. Nanka ukuthi mangaki ama-octave kupiyano:

1. I-Subcontroctave - inamanothi amathathu.
2. Inkontileka.
3. Okukhulu.
4. Okuncane.
5. Okokuqala.
6. yakho ememeza.
7. Okwesithathu.
8. Okwesine.
9. Okwesihlanu - kuqukethe inothi elilodwa.

Amanothi e-subcontroctave anemisindo ephansi kakhulu, eyesihlanu inenothi elilodwa elizwakala liphezulu kunamanye. Empeleni, abaculi kufanele badlale la manothi kuyaqabukela. Amanothi asetshenziswa kakhulu asuka kwenkulu kuya kweyesithathu i-octave.

Uma kunezikhawu eziningi kupiyano njengoba kunama-octaves ophiyano, khona-ke ama-octaves kuphiyano i-synthesizer zihluke ngenani kumathuluzi abonisiwe. Lokhu kungenxa yokuthi i- i-synthesizer inokhiye abambalwa. Ngaphambi kokuthenga insimbi yomculo, kufanelekile ukucabangela isici.

Ama-octaves amancane nawokuqala

Amanye ama-octave asetshenziswa kakhulu ama-octave amancane nawokuqala wepiyano noma i-pianoforte. Okokuqala octave kupiyano iphakathi nendawo, nakuba ingeyesihlanu ilandelana, kanti eyokuqala iyi-subcontroctave. Iqukethe amanothi obude obuphakathi ukusuka ku-261.63 kuya ku-523.25 Hz , eboniswa yizimpawu C4-B4. Amanothi abekwe ngezansi komsindo omncane we-octave uphansi ngokumaphakathi nemvamisa engu-130.81 kuya ku-261.63 Hz .

Amanothi e-octave yokuqala

Amanothi e-octave yokuqala agcwalisa imigqa emithathu yokuqala yezinti ze-treble clef. Izimpawu ze-octave yokuqala zibhalwe kanje:

1. TO - emugqeni wokuqala owengeziwe.
2. I-PE - ngaphansi komugqa wokuqala oyinhloko.
3. I-MI - igcwalisa umugqa wokuqala.
4. I-FA - ibhalwe phakathi kweyokuqala kanye ne yesibili imigqa.
5. USAWOTI – ku yesibili umbusi.
6. LA - phakathi kweyesithathu ne yesibili imigqa.
7. SI – emugqeni wesithathu.

Ama-Sharps namaflethi

Ukuhlelwa kwama-octave kupiyano nopiyano akubandakanyi okhiye abamhlophe kuphela kodwa nokhiye abamnyama. Uma ikhibhodi emhlophe ibonisa imisindo eyinhloko - amathoni, khona-ke emnyama - ukuhlukahluka kwabo okuphakanyisiwe noma okwehlisiwe - ama-semitones. Ngaphezu komhlophe, owokuqala octave iqukethe okhiye abamnyama: C-sharp, RE-Sharp, FA-sharp, G-Sharp, A-sharp. Ekubhalweni komculo, zibizwa ngengozi. Ukuze udlale ama-Sharps, kufanele ucindezele izinkinobho ezimnyama. Okuhlukile kuphela i-MI-sharp ne-SI-sharp: adlalwa kokhiye abamhlophe FA kanye ne-DO ye-octave elandelayo.

Ukuze udlale isicaba, kufanele ucindezele izinkinobho ezitholakala kwesokunxele - zinikeza umsindo ophansi we-semitone. Isibonelo, iflethi lika-D lidlalwa kokhiye abangakwesokunxele ku-D omhlophe.

Idlalwa kanjani ama-octaves ngendlela efanele

Ngemuva kokuthi umculi esekwazi kahle igama lama-octave kupiyano, kufanelekile ukudlala izikali - ukulandelana kwamanothi e-octave eyodwa. Ukuze ufunde, i-C major ihamba phambili. Kuyafaneleka ukuqala ngesandla esisodwa, ngokungaguquki futhi kancane, ngokubeka kahle iminwe kukhibhodi. Ukuze ufunde ukuthi ungakwenza kanjani lokhu, ungalanda isifundo. Uma udlala isikali ngesandla esisodwa siyazethemba futhi sicacile, kufanelekile ukwenza okufanayo nge yesibili isandla.

Kunezikali eziningi njenge-octave egcwele - 7. Adlalwa ngokuhlukana ngesandla esisodwa noma ezimbili. Njengoba ikhono likhula, kufanelekile ukwanda ijubane ukuze izihlakala zijwayele ukwelula. Kubalulekile ukufunda indlela yokudlulisa isisindo kusuka ezandleni zakho kuya okhiye, ukugcina amahlombe akho ekhululekile. Iminwe nezihlakala ziba namandla, zijwayelane nezikhawu.

Uma udlala izikali njalo, umqondo we \u200b\ I-u200boctaves ihlehliswa engqondweni, futhi izandla zizohamba ngokushesha phezu kwazo isikhathi ngasinye.

Rookie Amaphutha

Abaculi abasaqala benza amaphutha alandelayo:

1. Abanawo umqondo ojwayelekile mayelana nethuluzi, umshini walo.
2. Abazi ukuthi mangaki ama-octaves opiyano, abizwa ngokuthini.
3. Ziboshelwe kuphela ku-octave yokuqala noma ziqala isikali kuphela kunothi DO, ngaphandle kokushintshela kwamanye ama-octave namanothi.

Imibuzo Evame Ukubuzwa

Yikuphi okungcono ukudlala i-octave: ngesandla sonke noma nge-stroke yebhulashi?

Ama-octave alula kufanele adlalwe ngokusetshenziswa okusebenzayo kwesandla, ukubeka isandla phansi, kuyilapho ama-octaves ayinkimbinkimbi kufanele adlalwe ngesandla esiphakanyiswe phezulu.

Idlalwa kanjani ama-octaves ngokushesha?

Isandla nengalo kufanele kushube kancane. Ngokushesha lapho ukukhathala kuzwakala, isikhundla kufanele sishintshwe kusukela phansi kuya phezulu futhi ngokuphambene nalokho.

Ukufingqa

Isamba senani lama-octave kupiyano, upiyano noma upiyano omkhulu ngu-9, lapho ama-octave angu-7 agcwele, anamanothi ayisishiyagalombili. Vuliwe i-synthesizer , inani lama-octave lincike enanini lamanothi futhi lingase lihluke kumathuluzi akudala. Ngokuvamile, ezincane, zokuqala nezesibili octaves zisetshenziswa, kuyaqabukela - i-subcontroctave neyesihlanu octave . Ukuze ukwazi kahle ama-octave, umuntu kufanele adlale izikali, aqale ngokunensa isikhathi , ngesandla esisodwa nangokubeka kahle iminwe.
