Kev xaiv cov khoom siv rau cov twj paj nruag percussion yog qhov tseem ceeb hauv kev txiav txim siab lawv cov yam ntxwv ntawm lub suab, durability, thiab kev nthuav qhia. Cov khoom sib txawv muaj cov yam ntxwv tshwj xeeb ntawm qhov ntom ntom, elasticity, resonance kev ua tau zoo, thiab ruaj khov, cuam tshuam ncaj qha rau qhov ntsuas lub suab, timbre, txhawb nqa, thiab muaj zog ntau yam. Thaum lub sij hawm tsim thiab tsim cov txheej txheem, tsuas yog los ntawm kev tshawb fawb cov ntaub ntawv raws li cov cuab yeej hom, npaj siv, thiab kev coj noj coj ua zoo nkauj tuaj yeem ua tiav lub suab zoo tshaj plaws thiab ntev - tus nqi kav ntev.
Ionic percussion instruments feem ntau siv hlau, ntoo, thiab cov khoom siv hluavtaws ua vibrators. Metal materials such as steel, brass, bronze, and aluminum alloys, due to their high density and rigidity, produce bright, penetrating tones with long sustain, suitable for occasions requiring a clear tone, such as triangles, cymbals, and celesta. Txawv alloy ratios hloov cov qauv overtone thiab attenuation yam ntxwv; Piv txwv li, bronze cymbals nrog cov ntsiab lus siab tin ua rau cov nplua nuj, suab nrov, thaum siab - carbon steel nyiam ntse thiab meej. Ntoo imparts sov, mellow resonance rau suab paj nruag thiab feem ntau yog siv nyob rau hauv xylophones, marimbas, thiab ntoo ntses. Tropical hardwoods such as rosewood and mahogany have high density and uniform grain, providing rich and stable fundamental frequencies and overtones. Synthetic resin ntoo, thaum tuav resonance kev ua tau zoo, txhim kho cov dej tsis kam thiab tawg tsis kam, nthuav nws cov kev hloov mus rau ntau qhov chaw.
Membrane percussion instruments, sawv cev los ntawm nruas, feem ntau yog nyob ntawm kev sib xyaw ntawm lub taub hau thiab cov khoom siv plhaub rau lawv lub suab zoo. Drumheads feem ntau poob rau hauv ob pawg: tsiaj ntuj hides thiab hluavtaws polymer films. Ntuj hides, xws li cowhide thiab sheepskin, muaj ib tug sov so, elastic tone thiab rhiab heev rau huab cua thiab av noo, ua rau lawv haum rau tsoos thiab acoustic style. Synthetic hides, xws li polyester films, yog huab cua heev - tiv taus thiab muaj zog nro, tswj kev sib xws nyob rau hauv ntau qhov chaw thiab yog dav siv nyob rau hauv pop, jazz, thiab niaj hnub orchestral npaj. Nruas plhaub cov ntaub ntawv muaj xws li ntoo, hlau, thiab hluavtaws composites. Ntoo nruas shells muab ib tug nplua nuj resonance thiab txawv tonal txheej, nrog maple, birch, thiab mahogany txhua tus muaj lawv tus kheej cim. Hlau nruas plhaub, xws li steel, aluminium, thiab tooj liab, ua kom ci, projecting tones nrog huv si, crisp sustain. Composite nruas plhaub tawm tsam qhov sib npaug ntawm qhov hnyav thiab lub zog, ua rau lawv haum rau kev txav mus los thiab siv sab nraum zoov.
Shakers thiab accessory percussion instruments ua qhov tseem ceeb ntawm kev ntxhib los mos thiab tonal variation hauv lawv cov khoom xaiv. Kev sau sab hauv ntawm maracas tuaj yeem yog cog noob, iav hlaws, yas pellets, lossis hlau xuab zeb; qhov sib txawv ntawm qhov nruab nrab txiav txim siab qhov zoo ntawm lub suab thiab lub ntim. Cov khoom siv plhaub yuav tsum muaj qhov sib npaug ntawm qhov hnyav thiab ruaj khov, nrog xyoob, ntoo, hluavtaws cob, thiab hlau txhua tus muab lawv tus cwj pwm txawv. Cov ntaub ntawv ntawm tambourine lub taub hau thiab tswb cuam tshuam rau ob qho tib si tawm tsam thiab rattling timbres. Kev lig kev cai, nqaij tshis yog siv nrog lub tswb steel, thaum niaj hnub versions siv cov tawv nqaij sib xyaw nrog kub tswb, ntsuas qhov rhiab heev thiab ua haujlwm ntev.
Nyob rau hauv cov ntsiab lus ntawm globalization thiab cross- kab lis kev cai kev koom ua ke nyob rau hauv kev ua hauj lwm muaj tswv yim, kev xaiv cov ntaub ntawv yuav tsum tau txiav txim siab qhov tseeb thiab sustainability ntawm kab lis kev cai qhia. Cov cuab yeej siv niaj hnub ua feem ntau siv cov ntaub ntawv keeb kwm los khaws nws cov cim tonal thiab kab lis kev cai; Kev tsim khoom niaj hnub no, ntawm qhov tod tes, ua qhov tseem ceeb ntawm ib puag ncig kev phooj ywg thiab kev tswj hwm, tsim cov khoom siv hypoallergenic, rov ua dua tshiab, lossis cov khoom siv rov ua dua tshiab kom txo tau ib puag ncig lub nra.
Zuag qhia tag nrho, kev xaiv cov khoom siv rau cov cuab yeej percussion yog kev qhuab qhia dav dav uas suav nrog cov ntsiab lus acoustic, kev ua haujlwm zoo nkauj, thiab kev coj noj coj ua zoo nkauj. Kev sib raug zoo ntawm cov ntaub ntawv thiab cov cuab yeej ua haujlwm tsis tsuas yog tsim lub suab nrov thiab ruaj khov tab sis kuj txhim kho kev ua tau zoo thiab kev ua neej nyob, muab lub hauv paus ruaj khov thiab muaj peev xwm ua yeeb yam rau cov suab paj nruag thiab kev ua haujlwm.
