Octaves pa piyano

Nthawi yapakati pa zolemba ziwiri zofanana imatchedwa ndi octave . Kuti mudziwe m'modzi wa iwo, ndikwanira kupeza cholemba "chitani" pa kiyibodi ndipo, kusunthira mmwamba kapena pansi makiyi oyera, kuwerengera zidutswa zisanu ndi zitatu, kufikira cholemba chotsatira cha dzina lomwelo.

Kuchokera ku Latin, mawu akuti " octave ” amamasuliridwa kuti “wachisanu ndi chitatu”. Masitepe asanu ndi atatuwa amalekanitsa zolemba za ma octave awiri kuchokera kwa wina ndi mzake, kudziwa mafupipafupi - kuthamanga kwa oscillation. Mwachitsanzo, a pafupipafupi pa mawu akuti "la" octave imodzi ndi 440 Hz Ndipo pafupipafupi octave pamwamba ndi 880 Hz . Nthawi zambiri mwa zolemba ndi 2: 1 - chiŵerengero ichi ndichosangalatsa kwambiri kumva. Piyano yokhazikika imakhala ndi ma octave 9, kutengera kuti subcontroctave ili ndi manotsi atatu ndipo yachisanu imakhala ndi imodzi.

Octaves pa piyano

Mipata pakati pa manotsi omwewo a ma frequency osiyanasiyana ndi ma octaves pa piyano. Amapangidwa mkati ndi nambala yomweyo ndi dongosolo lomwelo monga pa piyano. Nawa ma octave angati pa piyano:

1. Subcontroctave - imakhala ndi zolemba zitatu.
2. Contractave.
3. Chachikulu.
4. Small.
5. Choyamba.
6. Lachiwiri kulira.
7. Chachitatu.
8. Chachinayi.
9. Chachisanu - chimakhala ndi cholemba chimodzi.

Zolemba za subcontroctave zili ndi mawu otsika kwambiri, chachisanu chimakhala ndi cholemba chimodzi chomwe chimamveka chokwera kuposa china chilichonse. M'zochita, oimba amayenera kuyimba zolemba izi kawirikawiri. Zolemba zomwe zimagwiritsidwa ntchito kwambiri zimachokera ku zazikulu mpaka octave yachitatu.

Ngati pali nthawi zambiri pa piyano monga pali ma octaves pa piyano, ndiye kuti ma octaves pa piyano synthesizer zimasiyana ndi zida zomwe zasonyezedwa. Izi ndichifukwa choti ma synthesizer ali ndi makiyi ochepa. Musanagule chida choimbira, ndi bwino kuganizira mbali yake.

Octave yaing'ono ndi yoyamba

Ena mwa ma octave omwe amagwiritsidwa ntchito kwambiri ndi ma octave ang'onoang'ono komanso oyamba a piyano kapena pianoforte. Choyamba octave pa limba lili pakati, ngakhale kuti ndi wachisanu mu mzere, ndipo woyamba ndi subcontroctave. Ili ndi zolemba zapakatikati kuchokera pa 261.63 mpaka 523.25 Hz , zosonyezedwa ndi zizindikiro C4-B4. Zolemba zomwe zili pansi pa octave yaying'ono zimamveka zotsika pang'ono ndi ma frequency a 130.81 mpaka 261.63 Hz .

Zolemba za octave yoyamba

Zolemba za octave yoyamba zimadzaza mizere itatu yoyambirira ya mphiko za chopingacho. Zizindikiro za octave yoyamba zalembedwa motere:

1. TO - pamzere woyamba wowonjezera.
2. PE - pansi pa mzere woyamba.
3. MI - imadzaza mzere woyamba.
4. FA - yalembedwa pakati pa woyamba ndi lachiwiri mizere.
5. SALT - pa lachiwiri wolamulira.
6. LA - pakati pa lachitatu ndi lachiwiri mizere.
7. SI - pamzere wachitatu.

Zakuthwa ndi ma flats

Kukonzekera kwa ma octave pa piyano ndi piyano kumaphatikizapo osati makiyi oyera komanso akuda. Ngati kiyibodi yoyera ikuwonetsa mawu akulu - ma toni, ndiye yakuda - mitundu yawo yokwezeka kapena yotsika - semitones. Kuwonjezera woyera, woyamba octave imakhala ndi makiyi akuda: C-lakuthwa, RE-lakuthwa, FA-lakuthwa, G-lakuthwa, A-lakuthwa. M'mawu oimba, amatchedwa ngozi. Kuti muyimbe nyimbo zakuthwa, muyenera kukanikiza makiyi akuda. Zokhazo ndizo MI-sharp ndi SI-sharp: zimaseweredwa pamakiyi oyera a FA ndi DO a octave yotsatira.

Kuti musewere mosabisa, muyenera kukanikiza makiyi omwe ali kumanzere - amatulutsa mawu otsika. Mwachitsanzo, D flat imaseweredwa pamakiyi akumanzere kwa D yoyera.

Momwe mungasewere ma octave molondola

Woimbayo atadziwa dzina la octave pa piyano, ndi bwino kusewera masikelo - ndondomeko ya zolemba za octave imodzi. Kuphunzira, C major ndi abwino. Ndikoyenera kuyamba ndi dzanja limodzi, mosasinthasintha komanso pang'onopang'ono, ndikuyika bwino zala pa kiyibodi. Kuti mudziwe momwe mungachitire izi, mutha kukopera phunzirolo. Posewera sikelo ndi dzanja limodzi ndi chidaliro komanso momveka bwino, ndikofunikira kuchita chimodzimodzi ndi lachiwiri dzanja.

Pali masikelo ochuluka monga ma octave athunthu - 7. Amaseweredwa mosiyana ndi dzanja limodzi kapena awiri. Pamene luso likukula, liyenera kuwonjezeka mayendedwe kotero kuti manja azolowera kutambasula. Ndikofunika kuphunzira momwe mungasamutsire kulemera kuchokera m'manja mwanu kupita ku makiyi, kusunga mapewa anu momasuka. Zala ndi ziwombankhanga zimakhala zolimba, zizolowerane ndi magawo.

Ngati mumasewera masikelo nthawi zonse, lingaliro la \u200b\ u200boctaves imayimitsidwa m'malingaliro, ndipo manja amayenda mwachangu pa iwo nthawi iliyonse.

Zolakwa za Rookie

Oyimba oyambira amalakwitsa izi:

1. Iwo alibe lingaliro wamba za chida, chipangizo chake.
2. Iwo sakudziwa kuti ndi ma octavu angati omwe ali pa piyano, chomwe iwo amatchedwa.
3. Amangomangirizidwa ku octave yoyamba kapena amayamba sikelo kuchokera pa cholembera DO, osasinthira ku ma octave ndi zolemba zina.

FAQ

Ndi chiyani chomwe chili bwino kusewera octave: ndi dzanja lonse kapena ndi burashi?

Ma octave opepuka amayenera kuseweredwa ndikugwiritsa ntchito dzanja mwachangu, ndikuyika dzanja pansi, pomwe ma octave ovuta amayenera kuseweredwa ndi dzanja lokwezeka kwambiri.

Momwe mungasewere ma octave mwachangu?

Dzanja ndi mkono ziyenera kukhala zolimba pang'ono. Pamene kutopa kumamveka, malowa ayenera kusinthidwa kuchokera kumunsi kupita kumtunda komanso mosiyana.

Kuphatikizidwa

Chiwerengero chonse cha ma octave pa piyano, piyano kapena piyano yayikulu ndi 9, pomwe ma octave 7 ndi odzaza, okhala ndi manotsi asanu ndi atatu. Yambani ndi synthesizer , chiwerengero cha octaves chimadalira chiwerengero cha zolemba ndipo zingakhale zosiyana ndi zida zakale. Nthawi zambiri, yaing'ono, yoyamba ndi yachiwiri octave amagwiritsidwa ntchito, kawirikawiri - subcontroctave ndi yachisanu octave . Kuti adziwe bwino ma octave, munthu ayenera kusewera masikelo, kuyambira pang'onopang'ono nthawi , ndi dzanja limodzi ndi kuika bwino zala.
