style="text-indent:25px">曾經(jīng)被譽為“魔鬼鋼琴”的自動演奏鋼琴，吸引了無數(shù)人的眼球。魔鬼鋼琴其實就是鋼琴自動演奏系統(tǒng)。較初形式（出現(xiàn)在19世紀末）是在普通鋼琴前加用一部可移動的“演奏器”（player），外形極似一架小型足踏簧風(fēng)琴，有一排65-88個“木手指”置于普通鋼琴鍵盤上方。演奏器用打孔紙卷（打孔位置與鋼琴譜相符）操縱；用足踏風(fēng)箱鼓風(fēng)，風(fēng)通過紙卷緩緩轉(zhuǎn)動的紙卷上的孔位，驅(qū)動機械連動相應(yīng)的“木手指”擊琴鍵奏出音樂。此后又有設(shè)計將外附的演奏器直接裝置于鋼琴內(nèi)部，數(shù)碼鋼琴手感怎么樣，并可控制速度，數(shù)碼鋼琴手感怎么樣、力度、踏板等。自動鋼琴在20世紀20年代的歐洲曾廣為流行于家庭娛樂，有過兩年內(nèi)生產(chǎn)50萬臺的紀錄；至30年代由于無線電及唱機的興起，才漸被淘汰。但因為紙卷打孔在數(shù)量上不受人手十指的局限，鋼琴上的音數(shù)和音域都可盡量發(fā)揮運用，故自動鋼琴仍受現(xiàn)代作曲家的青睞。長期不用的琴更容易被老鼠噬咬，數(shù)碼鋼琴手感怎么樣。應(yīng)該定期打開上門和下門檢查，以防不測。數(shù)碼鋼琴手感怎么樣</p><div

style="text-indent:25px">鋼琴的優(yōu)缺點：（1）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；而立式琴為節(jié)省空間，共振腔不大，琴弦相互交錯、影響共振，一定程度上改變了中音區(qū)的音色，使立式琴的動態(tài)范圍和音色統(tǒng)一性受到了很大限制。（2）擊弦器的區(qū)別三角琴的擊弦器是臥式的，按鍵時弦錘向上抬起，擊弦后靠重力下落，這種設(shè)計使整個擊弦器力臂足夠，下鍵有實在感，由于依靠重力下落，琴鍵恢復(fù)迅速。立式琴由于把弦錘豎起，下鍵時弦錘重力的力臂更小，這導(dǎo)致立式琴的琴鍵恢復(fù)緩慢、手感不均、壽命相對三角琴較短。另外，由于三角琴空間更大，弦錘距離琴弦更遠，從而使三角琴有更大的動態(tài)空間。網(wǎng)上學(xué)數(shù)碼鋼琴入門自學(xué)教程電子鋼琴擁有更小巧的外觀，便于攜帶，在運輸和搬用的過程中由于體積小，質(zhì)量輕，擁有更好的表現(xiàn)。</p><div

style="text-indent:25px">與鋼琴區(qū)別——方便性：普通鋼琴的重量一般是在200多公斤左右，移動起來極為不便，我們曾經(jīng)看到一些學(xué)校的演出，人們好不容易又拖又抬地把鋼琴搬到演出現(xiàn)場，真正演出的時候懂行的人能夠聽出來它的音已經(jīng)不準了。為什么？因為鋼琴在搬動的過程中不可避免地受到震動，琴弦的張力發(fā)生變化，音已經(jīng)”黃”了。要知道鋼琴的很多音都是通過3根同樣音高的弦發(fā)出來的，只要一根弦跑音，就會”黃”。這就是為什么鋼琴即使是在沒有任何移動的情況下每年都必須調(diào)律1-2次的原因，更不用說移動了。電鋼琴的重量一般都只是在幾十斤左右，搬動起來非常方便，也不會擔(dān)心跑音的情況，因為電鋼琴不需要調(diào)律。</p><p style="text-indent:25px">電子琴和鋼琴的區(qū)別：電子琴和鋼琴是兩種不同的樂器，首先它們在外觀上就有不同，其次它們琴鍵的數(shù)量也不同，另外在演奏時力度的控制也不同。電鋼琴和電子琴的另一個區(qū)別是按鍵和他們的敏感度設(shè)置。電子琴以具有塑料外觀和感覺的按鍵而聞名，這些按鍵對它們沒有太大的作用，當(dāng)然也沒有任何分級的錘子動作。很多電子琴也沒有任何的觸摸靈敏度，這意味著每次你彈奏一個音符時，每次都會有相同的速度。電鋼琴有很大的不同，一些制造商甚至要制作真正的木制琴鍵，或者至少給他們一個烏木和象牙質(zhì)地，以增加現(xiàn)實感。他們大多數(shù)是加權(quán)和分級錘行動技術(shù)，它復(fù)制了一個真正的鋼琴鍵擊打鋼琴弦的動作。琴鍵也是漸變的，這意味著低音琴鍵比高音琴鍵更重，就像真正的鋼琴一樣。鋼琴它不耐碰撞，受到碰撞，輕則影響美觀。</p><div

style="text-indent:25px">電鋼琴VS真鋼琴：1、鋼琴發(fā)聲：物理發(fā)聲，屬于實物發(fā)聲，像是我們用木棍敲玻璃杯一樣。榔頭擊弦而發(fā)音---這就是鋼琴發(fā)音原理較簡單的陳述。由于鋼琴是物理發(fā)聲，所以鋼琴的構(gòu)造、琴弦的共鳴等許多因素都影響著鋼琴的音色，而電鋼琴卻沒有這些構(gòu)造，在一些高級的電鋼琴上可能會有這些“額外聲音”的采樣，不過采樣畢竟是采樣，永遠只能是接近真實。所以大多數(shù)鋼琴專業(yè)的人都更喜歡真鋼琴。2、電鋼琴發(fā)聲：屬于電子發(fā)聲，電鋼琴是電子元器件傳感發(fā)聲。電鋼琴的發(fā)聲原理是將鍵盤當(dāng)做通電的開關(guān)，當(dāng)按下琴鍵的時候，鋼琴內(nèi)部就開始工作，晶振會發(fā)出一定頻率的波形，通過分頻器將波形放大，再透過揚聲器將聲音傳送出去，人們就能夠聽到優(yōu)美的旋律了。鋼琴可以用大螺絲從木箱外面擰到鋼琴背面的支架柱上。上海買一臺成人鋼琴購買</p><p

style="text-indent:25px">電鋼琴的發(fā)展歷史當(dāng)今的人們討論的“電鋼琴是電子琴家族的一個分支，嚴格來講，應(yīng)該叫“數(shù)碼鋼琴，一些地區(qū)的人稱其為“數(shù)位鋼琴。在21世紀已經(jīng)約定俗成地把“數(shù)碼鋼琴叫做“電鋼琴。它的發(fā)聲原理是集成電路經(jīng)過對按鍵力度，踏板情況，按鍵速度等物理狀況進行運算，調(diào)用相應(yīng)的采樣信號，經(jīng)過一定的運算后回放。所有使用了數(shù)字采樣技術(shù)，模擬鋼琴音色的樂器都屬于此類。一般電鋼琴感應(yīng)按鍵力度的原理是：琴鍵下方安置兩個感應(yīng)觸點，通過計算壓下上感應(yīng)點與下感應(yīng)點的時間差來確定擊鍵速度。部分高級鍵盤，有三個感應(yīng)觸點，可使力度感應(yīng)更為精確。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，造價全花在了鍵盤手感上。數(shù)碼鋼琴手感怎么樣</p><p
