I-Polyphony kuPiyano Yedijithali

I-Polyphony (kusuka kuLatini elithi “polyphonia” – imisindo eminingi) igama elisho ukuzwakala kanyekanye kwenani elikhulu lamazwi, okubala izinsimbi. I-Polyphony isuka enkathini yama-motets kanye nama-organum enkathi ephakathi, kodwa yachuma emakhulwini ambalwa eminyaka kamuva - ngesikhathi sika-JS Bach, lapho. i-polyphony wathatha isimo se-fugue ngezwi elilinganayo eliholayo.

I-Polyphony kuPiyano Yedijithali

Kumapiyano esimanje kagesi anokhiye abangama-88, izwi lama-256 i-polyphony kungenzeka . Lokhu kungenxa yokuthi iphrosesa yomsindo ezinsimbini zedijithali iyakwazi ukuhlanganisa ukuvumelana nokudlidliza kwegagasi ibe uhlelo ngezindlela ezihlukene. Yile ndlela izinhlobo eziningana ze-polyphony ezizalwa ngayo kumakhibhodi wesampula yamanje, kunkomba lapho ukujula nokucebile, imvelo yomsindo wensimbi incike ngokuqondile.

Lapho inani lamazwi liphezulu kupharamitha ye-polyphony yepiyano, umsindo ohlukile nogqamile umculi angawuthola.

Izinhlobo zamanani

I-polyphony upiyano lwe-elekthronikhi ngu-32, 48, 64, 128, 192 kanye no-256 - izwi. Nokho, abakhiqizi bezinsimbi abahlukene bahluke kancane ukukhetha izindlela, ngakho-ke kungenzeka ukuthi ipiyano ene-polyphony yamazwi angu-128, isibonelo, izoba nomsindo ocebile kunedivayisi ene-polyphony yamazwi angu-192.

Okudume kakhulu inani eliyisilinganiso lepharamitha ye-polyphony yedijithali yamayunithi angu-128, okujwayelekile kumathuluzi ezinga lochwepheshe. Yebo, ungagxila kupharamitha ephezulu (amazwi angama-256), nokho, njengoba umkhuba ubonisa, kunengqondo ukuthola ithuluzi elimangalisayo elinamakhono ajwayelekile wepholyfoni. I-polyphony ecebile ayidingekile kumdlali we-novice, njengoba umdlali oqalayo ngeke awazise ngokugcwele amandla ayo.

Uhlolojikelele lwamapiyano edijithali

Phakathi kwezinketho zesabelomali, ungacabangela amapiyano e-electronic ane-polyphony yamazwi angu-48. Amamodeli anjalo, ngokwesibonelo, anjalo I-CASIO CDP-230R SR futhi I-CASIO CDP-130SR . Izinzuzo zalawa piyano edijithali izindleko zebhajethi, isisindo esilula (cishe 11-12 kg), ikhibhodi enesisindo esingukhiye ongu-88 kanye nesethi eyisisekelo yezici ze-elekthronikhi.

Amapiyano anamazwi angu-64, isibonelo, yiwo Yamaha P-45 futhi Amamodeli we-Yamaha NP-32WH . Ithuluzi lokuqala liqukethe idizayini yomzimba eyinkimbinkimbi kakhulu yemodeli eshibhile, usayizi omncane (11.5 kg) kanye nomsebenzi we-semi-pedal oqinile. The upiyano lwesibili luhamba ( i-synthesizer format), ifakwe isitendi somculo, i-metronome, ukusebenza kwamahora angu-7 kusuka ebhethri enesisindo esingu-5.7 kg kuphela.

Abaculi abathuthuke kakhulu badinga insimbi okungenani ene-polyphony yamazwi angu-128. Ipiyano enamaphuzu angu-192 izophinde ibe yinto enhle kakhulu yokutholwa komdlali wopiyano ozimisele. Inani kanye nekhwalithi kuhlanganiswe kahle ku- Imodeli ye-Casio PX-S1000BK . Le nsimbi yaseJapan inikezwe inqwaba yezici, kusukela kusenzo sesando se Smart Ikhibhodi Yesenzo Se-Hammer Esikalisiwe ibe nesisindo esingu-11.2 kg. Ifaka idizayini emnyama yakudala enomzimba wesiqephu esisodwa nokuphumula komculo, upiyano lukagesi lwe-PX-S1000BK lunezici ezilandelayo:

• Ikhibhodi yokhiye ongu-88 enesisindo esigcwele ngamaleveli angu-3 wokuzwela kokuthinta;
• impendulo yesando, i-damper resonance, ukuthinta - isilawuli;
• ukusebenza kwebhethri, i-USB, izingoma zedemo eyakhelwe ngaphakathi.

Amapiyano kagesi anepharamitha ye-polyphony yamayunithi angama-256 azoba izibonelo zesikhombi esiphezulu se-polyphony emsindweni. Amathuluzi alolu hlobo avame ukuba nezindleko eziphakeme, noma kunjalo, kokubili ngokuklama nangokwezici zabo zobuchwepheshe, angamamodeli asezingeni eliphezulu. Ipiyano yedijithali ye-YAMAHA CLP-645DW enohlelo lwakudala olunama-pedal amathathu kanye nekhibhodi yokhuni yekhwalithi enhle kakhulu ngisho nangokubukeka ifana nensimbi ebizayo ye-acoustic. Phakathi kwezici zemodeli kufanelekile ukuqaphela:

• Ikhibhodi yokhiye abangu-88 (ukuphela kwezinyo lendlovu);
• ngaphezu kwe-10 izilungiselelo zokuzwela kokuthinta;
• umsebenzi wokucindezelwa okungaphelele kwe-pedal;
• Isibonisi se-LCD se-Dot egcwele;
• I-Damper nentambo ukuzwela ;
• Ubuchwepheshe be-Intelligent Acoustic Control (IAC).

Futhi isibonelo esihle kakhulu sensimbi yedijithali ene-polyphony ye-256-voice izoba upiyano lwe-CASIO PX-A800 BN. Imodeli yenziwa emthunzini "we-oki" futhi ilingisa ngokuphelele ukuthungwa kwezinkuni. Inomsebenzi wokulingisa ama-acoustics ekhonsathi, iphrosesa yomsindo yohlobo lwe-AiR kanye nekhibhodi yokuthinta eneleveli engu-3.

Izimpendulo emibuzweni

Iyiphi inkomba ye-polyphony yepiyano yedijithali ezoba ngcono kakhulu ezingeni lokuqala lezifundo zengane esikoleni somculo?

Insimbi ene-polyphony yamayunithi angama-32, 48 noma angama-64 ilungele ukuqeqeshwa.

Iyiphi imodeli yepiyano ye-elekthronikhi engasebenza njengesibonelo sebhalansi yentengo nekhwalithi ene-polyphony yamazwi angu-256? 

Enye yezinketho ezinhle kakhulu ingabhekwa njengepiyano I-Medeli DP460K

Ukufingqa

I-Polyphony kupiyano ye-elekthronikhi ipharamitha yekhwalithi ebalulekile ethinta ukugqama komsindo wensimbi namandla ayo okuzwakalayo. Kodwa-ke, ngisho nezilungiselelo ze-polyphony ezimaphakathi, ungathatha upiyano oluhle lwedijithali. Amamodeli ane-polyphony ephakeme kakhulu engenzeka azoba ukutholwa okuhle kakhulu kochwepheshe nabanolwazi.
