一、電子琴和鋼琴有什么區別
發(fa)聲原理不(bu)一(yi)(yi)樣(yang)(yang),電(dian)(dian)(dian)(dian)鋼(gang)(gang)琴(qin)(qin)(qin)是(shi)電(dian)(dian)(dian)(dian)子(zi)(zi)元器件(jian)傳(chuan)感發(fa)聲,電(dian)(dian)(dian)(dian)子(zi)(zi)琴(qin)(qin)(qin)通過振(zhen)動器和分(fen)頻(pin)器發(fa)聲。音色不(bu)一(yi)(yi)樣(yang)(yang),電(dian)(dian)(dian)(dian)鋼(gang)(gang)琴(qin)(qin)(qin)一(yi)(yi)般只有(you)幾(ji)種(zhong)常用音色,也(ye)就五(wu)六種(zhong)。電(dian)(dian)(dian)(dian)子(zi)(zi)琴(qin)(qin)(qin)一(yi)(yi)般都有(you)幾(ji)百種(zhong)音色。 手(shou)指技法不(bu)一(yi)(yi)樣(yang)(yang),電(dian)(dian)(dian)(dian)鋼(gang)(gang)琴(qin)(qin)(qin)對手(shou)指間的要求其細膩程度和獨(du)立(li)性(xing)都是(shi)比較高的,電(dian)(dian)(dian)(dian)子(zi)(zi)琴(qin)(qin)(qin)不(bu)需要什么手(shou)指技法。踏(ta)(ta)板不(bu)一(yi)(yi)樣(yang)(yang),電(dian)(dian)(dian)(dian)鋼(gang)(gang)琴(qin)(qin)(qin)有(you)踏(ta)(ta)板,而電(dian)(dian)(dian)(dian)子(zi)(zi)琴(qin)(qin)(qin)沒(mei)有(you)踏(ta)(ta)板。琴(qin)(qin)(qin)鍵數不(bu)一(yi)(yi)樣(yang)(yang),電(dian)(dian)(dian)(dian)鋼(gang)(gang)琴(qin)(qin)(qin)和鋼(gang)(gang)琴(qin)(qin)(qin)一(yi)(yi)樣(yang)(yang)是(shi)88鍵,電(dian)(dian)(dian)(dian)子(zi)(zi)琴(qin)(qin)(qin)有(you)64、76、88等不(bu)同的鍵數。
二、電子琴的價格是多少
一般來說電子琴的價格大多在幾千元,具體會因為電子琴品牌、功能、型號的(de)不(bu)同(tong)而有區別。初學(xue)(xue)者選購電子(zi)琴,一定不(bu)要(yao)選擇(ze)幾百元的(de)玩具電子(zi)琴,對以后(hou)的(de)學(xue)(xue)習會造成很大影響。除此之外,選購電子(zi)琴需要(yao)注意外觀、揚聲器功率大小和鍵盤力度(du)(du)感應靈敏度(du)(du)、功能布(bu)局(ju)的(de)合理性、以及(ji)音色、伴(ban)奏(zou)曲風的(de)擴(kuo)展性和演(yan)奏(zou)效果,以及(ji)琴的(de)可編輯性。
三、電子琴怎么調音
檢(jian)(jian)(jian)查所有(you)的操縱部(bu)(bu)分如按(an)鍵、拉桿、旋鈕等,看(kan)是否有(you)異(yi)常現(xian)象(xiang)。這部(bu)(bu)分檢(jian)(jian)(jian)查很重(zhong)要(yao),因為它直接(jie)影響到(dao)演(yan)奏(zou)(zou)。把音(yin)(yin)(yin)量開(kai)(kai)到(dao)最大點,靠近放音(yin)(yin)(yin)部(bu)(bu)分傾聽(ting),檢(jian)(jian)(jian)查否有(you)較大的交流噪聲(sheng)。高檔琴(qin)(qin)應聽(ting)不(bu)(bu)到(dao)這種噪聲(sheng),一(yi)(yi)般(ban)(ban)琴(qin)(qin)的噪聲(sheng)也不(bu)(bu)應過大。打(da)開(kai)(kai)琴(qin)(qin)音(yin)(yin)(yin)色,將音(yin)(yin)(yin)量開(kai)(kai)到(dao)略大于(yu)一(yi)(yi)般(ban)(ban)演(yan)奏(zou)(zou)的音(yin)(yin)(yin)量,然后進(jin)行演(yan)奏(zou)(zou)。先(xian)彈(dan)一(yi)(yi)個(ge)音(yin)(yin)(yin),后再彈(dan)兩個(ge)音(yin)(yin)(yin)或三個(ge)音(yin)(yin)(yin)的和弦。檢(jian)(jian)(jian)查是否有(you)琴(qin)(qin)的共(gong)振噪聲(sheng),如共(gong)振噪音(yin)(yin)(yin)明(ming)顯,說明(ming)有(you)些部(bu)(bu)件(jian)松動或組(zu)裝的不(bu)(bu)理想。高檔琴(qin)(qin)或好的琴(qin)(qin)不(bu)(bu)應有(you)這種現(xian)象(xiang),普通琴(qin)(qin)的共(gong)振雜音(yin)(yin)(yin)也不(bu)(bu)宜過大。
