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。北京上海華新鋼琴兒童電鋼琴實(shí)際上一臺(tái)較好的電鋼琴的音色較大程度上接近了較完美的真鋼。</p><div

style="text-indent:25px">彈黑鍵要像彈白鍵那樣立起手指嗎：顯然，白鍵、黑鍵長短寬度不一，離觸鍵的手指高度也不一樣，這必然造成觸感、觸鍵方式、手指彎曲度的差異。就是說，彈黑鍵肯定不會(huì)也不要像彈白鍵那樣立著手指，尤其是黑白鍵連續(xù)彈或交錯(cuò)彈奏的時(shí)侯。而且，即使彈白鍵也千萬別刻意或過分的立著手指，一切都要自然，符合手的天然舒適狀態(tài)。順便說下有關(guān)的其他問題，很多情況下（按順序彈黑白鍵或交錯(cuò)彈黑白鍵），整手不光要做橫向運(yùn)動(dòng)，有時(shí)也要做縱向（前后）運(yùn)動(dòng)，這有利于黑白鍵彈奏的連貫性，或者說樂句旋律的連貫性。具體表現(xiàn)在有時(shí)彈黑鍵手要往里（前）伸，有時(shí)彈白鍵手要外（后）退，這些適時(shí)的調(diào)整是有用的，也是必須的。</p><p style="text-indent:25px">電子琴內(nèi)部結(jié)構(gòu)及發(fā)聲原理電子琴內(nèi)部結(jié)構(gòu)及發(fā)聲原理鍵盤式電子琴聲音豐富、優(yōu)美，有變音裝置，能發(fā)出多種不同的音色，可以作為獨(dú)特的樂器進(jìn)行演奏，還能代替?zhèn)鹘y(tǒng)的風(fēng)琴、鋼琴供音樂課教學(xué)。傳統(tǒng)樂器的聲音是通過機(jī)械的方法產(chǎn)生的，電子琴的聲音是用電產(chǎn)生的。振蕩器是根據(jù)需要產(chǎn)生一定頻率的振蕩信號(hào)，振蕩信號(hào)通過分頻器分解成不同頻率的信號(hào)輸送到放大器，放大器將信號(hào)放大，推動(dòng)揚(yáng)聲器發(fā)出聲音。鍵盤實(shí)際是一些開關(guān)，如果沒有鍵盤，許多種頻率的信號(hào)一齊進(jìn)到放大器里，通過揚(yáng)聲器發(fā)出的聲音就會(huì)亂七八糟，不成音樂。按下鍵盤的一支鍵，就等于接通一只開關(guān)，只允許某一種頻率的信號(hào)通過到放大器里去，揚(yáng)聲器就發(fā)出一個(gè)音來。這樣，按照一定的演奏規(guī)律來按鍵，就能奏出美妙的音樂來。電源的任務(wù)是給各部分供電。如果受條件影響，室內(nèi)濕度較大，可以在琴下面鋪一張地板革或塑料薄膜隔潮。</p><div

style="text-indent:25px">鋼琴保養(yǎng)：防潮鋼琴大部分的構(gòu)件是木質(zhì)和鐵質(zhì)材料，其結(jié)合是靠螺絲擰合和膠水膠合的，所以，如果鋼琴受潮的時(shí)候，會(huì)使鋼琴的鋼絲和其他金屬部件生銹，并且音板、榔頭等木質(zhì)的部件會(huì)受潮而變形，嚴(yán)重的時(shí)候，部件間的膠水會(huì)變質(zhì)，從而使相關(guān)的部件脫膠脫落，因此，在選擇放置鋼琴的位置時(shí)，應(yīng)該放置在一些干燥通風(fēng)處，條件允許小，可用木板臺(tái)墊高整臺(tái)鋼琴，并在周圍撒一些生石灰等防潮劑，同時(shí)也可買一些干燥劑放置在鋼琴內(nèi)，并定期把期可把干燥劑拿出來曬干再放進(jìn)去，進(jìn)行二次使用。有的人為了保護(hù)鋼琴，用絨布做成琴套把鋼琴從上到下包得嚴(yán)嚴(yán)的，甚至再加上塑料布等好幾層包起來。其實(shí)，這反倒不利于鋼琴的保養(yǎng)，把鋼琴包裹得密不透風(fēng)的情況，鋼琴反倒更容易受潮，因?yàn)榭諝獾牟涣魍?，使得鋼琴更易受潮，其?shí)只要買一個(gè)專業(yè)的琴罩蓋住就可以了，這樣還更加美觀，但如果不小心把較多的水濺進(jìn)鋼琴內(nèi)部的情況下，不懂的用戶一定不能自己拆卸自己搞，應(yīng)該及時(shí)請(qǐng)懂行的人進(jìn)行處理。鋼琴共振空間三角琴的共振腔結(jié)構(gòu)合理、空間足夠，這使三角琴能發(fā)出更大的聲音。北京上海華新鋼琴兒童電鋼琴</p><p
