style="text-indent:25px">電鋼琴主要種類：1、假“數(shù)碼鋼琴”，玩具琴，其實(shí)就是電腦上用的玩具鍵盤，價(jià)格數(shù)百元。2、雜牌數(shù)碼鋼琴，有鋼琴的外觀，手感類似玩具電子琴的手感，音色與廉價(jià)電子琴的音色相近，價(jià)格數(shù)百元至三千元。這一類有些唬人，不過你只要親自彈一個(gè)鍵就會(huì)立刻識(shí)別出來了。3、正牌較高數(shù)碼鋼琴，具有鋼琴的外觀，逼真的手感，較好的音色，價(jià)格在6000-20000元。這類琴基本上都是日本的品牌。這一類琴很不錯(cuò)，值得購買。與鋼琴區(qū)別——手感：電鋼琴是否能夠達(dá)到鋼琴的手感，這是爭(zhēng)議較多的一個(gè)問題。因?yàn)榘l(fā)聲原理的不同導(dǎo)致了這個(gè)較大的爭(zhēng)論。鋼琴是通過內(nèi)部的機(jī)械的傳動(dòng)將演奏者手指的動(dòng)作和力度傳達(dá)到鋼琴的“榔頭” 上，使得“榔頭”再敲擊琴弦時(shí)才產(chǎn)生了琴聲，而電鋼琴這個(gè)機(jī)械的傳動(dòng)動(dòng)作是沒有的，只能說是盡力模擬真鋼琴的手感，但是這種手感又是鋼琴演奏較重要的一種感覺，它決定了演奏者對(duì)鋼琴的控制并通過這種控制表現(xiàn)音樂。廣東買哪款鋼琴電鋼琴88鍵重錘鋼琴讓聲部間的和聲能夠更好的連接和聲的彈奏效果直接影響到整部作品的優(yōu)劣。</p><div

style="text-indent:25px">鋼琴的音量與力度特點(diǎn)：音量即響度。鋼琴不但音域?qū)拸V，而且它的音量宏大，力度變化明顯。它的音量足以和一個(gè)相當(dāng)規(guī)模的管弦樂隊(duì)相媲美，并能在管弦樂隊(duì)的聲群中表現(xiàn)突出的旋律及伴奏音型。它的音量和力度變化可由極弱(PPP)至特強(qiáng)(fff)，并在這些范疇內(nèi)巧妙地組合。鋼琴不*能演奏山寧馨纖細(xì)、優(yōu)雅安靜、朦朧含蓄、輕聲細(xì)語的音樂意境，而且也能演奏出鏗鏘有力、洶涌澎湃、群情激昂、絢麗輝煌的音樂意境。從人的生理上講，鋼琴音樂的強(qiáng)弱或響度的對(duì)比變化，足以使人耳受到較強(qiáng)的刺激。據(jù)測(cè)定，鋼琴的聲壓級(jí)范圍可以弱至四、五分貝，強(qiáng)至七、八十分貝以上，并能達(dá)到許多層次和多種組合的音響形態(tài)。正因如此，現(xiàn)代鋼琴音樂在力度層次方面的組合被不斷挖掘，并加以引發(fā)或利用。我們知道，人耳感受聲音強(qiáng)弱或力度變化都是由發(fā)音體振動(dòng)產(chǎn)生聲波造成空氣壓力變化而形成的。通常，發(fā)音體產(chǎn)生振幅的大小決定音量的大小和強(qiáng)弱，偌大的鋼琴 *憑著不同力度觸鍵，變換著弦槌瞬間的擊(激)弦速度和質(zhì)量，因而產(chǎn)生出由弱至強(qiáng)的各種力度的層次變化，產(chǎn)生非凡特質(zhì)的音響，構(gòu)成鋼琴特有的“氣質(zhì)”。</p><p

piano），是一種電聲樂器。它是二十世紀(jì)六七十年代興起，八十年代至九十年代早期流行的一種用于在某些場(chǎng)合代替鋼琴的樂器。電鋼琴的發(fā)聲原理是將鍵盤作為通斷開關(guān)，形成電泳，一旦按下琴鍵，內(nèi)部的晶振開始工作，形成脈沖產(chǎn)生一定頻率的波形，接著經(jīng)過分頻器的放大，送入揚(yáng)聲器發(fā)聲。整個(gè)發(fā)聲過程依靠簡(jiǎn)單的分頻模擬電路，所以鍵盤沒有力度和擊弦感覺，聲音也較為機(jī)械單調(diào)。早期的電子鋼琴是比較專一化地、只有幾種鋼琴或類鋼琴的音色，能調(diào)音量，除此之外，造價(jià)全花在了鍵盤手感上。隨著人們對(duì)于音樂的喜好多元化，部分電鋼琴加裝上了成套的音色、節(jié)奏與伴奏控制。根據(jù)音色、節(jié)奏、功能等作為區(qū)分，可把電鋼琴分為純電鋼琴和多功能電鋼琴。電鋼琴還兼有電子琴乃至合成器的功能，有很多音色和節(jié)奏可以選擇，還可以很方便地移調(diào).廣東買哪款鋼琴電鋼琴88鍵重錘</p><p
