Isitho sikagesi: ukwakheka kwensimbi, isimiso sokusebenza, umlando, izinhlobo, ukusetshenziswa

Ngo-1897, unjiniyela waseMelika uThaddeus Cahill wasebenza emsebenzini wesayensi, efunda isimiso sokukhiqiza umculo ngosizo lwamanje kagesi. Umphumela womsebenzi wakhe kwaba ukusungulwa okubizwa ngokuthi "Telarmonium". Idivayisi enkulu enamakhibhodi esitho yaba umsunguli wensimbi entsha yekhibhodi yomculo. Bayibiza ngesitho sikagesi.

Idivayisi kanye nesimiso sokusebenza

Isici esiyinhloko sensimbi yomculo yikhono lokulingisa umsindo wesitho somoya. Enhliziyweni yedivayisi kukhona i-oscillation generator ekhethekile. Isignali yomsindo ikhiqizwa isondo lemisindo eliseduze nendawo yokuthatha. I-pitch incike enanini lamazinyo esondo kanye nesivinini. Amasondo e-synchronous motor motor anesibopho sobuqotho besistimu.

Amafrikhwensi ethoni acace ngokwedlulele, ahlanzekile, ngakho-ke, ukuze ukhiqize kabusha imisindo ye-vibrato noma emaphakathi, idivayisi ifakwe iyunithi ehlukile ye-electromechanical ene-capacitive coupling. Ngokushayela i-rotor, ikhipha amasignali ahlelwe futhi ahlelwe kumjikelezo we-electronic, ukukhiqiza kabusha umsindo ohambisana nesivinini sokujikeleza kwe-rotor.

Umlando

I-telharmonium kaCahill ayizange ithole impumelelo ebanzi kwezohwebo. Yayinkulu kakhulu, futhi kwakufanele idlalwe ngezandla ezine. Sekudlule iminyaka engu-30, omunye waseMelika, uLawrence Hammond, wakwazi ukusungula nokwakha isitho sakhe sikagesi. Wathatha ikhibhodi yepiyano njengesisekelo, wayenza ibe yesimanje ngendlela ekhethekile. Ngokusho kohlobo lomsindo we-acoustic, isitho sikagesi saba yi-symbiosis ye-harmonium nesitho somoya. Kuze kube manje, abanye abalaleli ngephutha babiza insimbi yomculo ngokuthi “electronic”. Lokhu akulungile, ngoba umsindo ukhiqizwa ngokunembile ngamandla ombane kagesi.

Isitho sikagesi sokuqala sikaHammond sangena ngokushesha kubantu abaningi. Amakhophi angu-1400 athengiswa ngokushesha. Namuhla, kusetshenziswe izinhlobo eziningana: isonto, studio, ikhonsathi. Emathempelini aseMelika, isitho sikagesi savela cishe ngokushesha ngemva kokuqala kokukhiqiza ngobuningi. Isitudiyo besivame ukusetshenziswa amabhendi amakhulu ekhulu lesi-XNUMX. Isiteji sekhonsathi siklanywe ngendlela evumela abadlali ukuthi babone noma yiziphi izinhlobo zomculo esiteji. Futhi lokhu akuyona nje imisebenzi edumile kaBach, Chopin, Rossini. Isitho sikagesi silungele ukudlala i-rock ne-jazz. Yasetshenziswa emsebenzini wabo yiBeatles kanye ne-Deep Purple.
