style="text-indent:25px">頻率排列和琴鍵排列：當(dāng)然這不能決定琴鍵必須是等比數(shù)列，因為如果你聽到兩個音不太好區(qū)分，那么只要增大它們的頻率差即可，也就是說，耳朵的限制只能導(dǎo)致越到高音區(qū)，頻率差越大而已。但是從數(shù)學(xué)的角度，我們可以證明這些音的分布必須是等比數(shù)列。這也就是我認(rèn)為的第二個原因。我們希望琴鍵的排列具有周期性，江蘇華星鋼琴電子琴，這樣以便鋼琴家找到每一個音的位置。較方便的獲取周期的方式就是：一巴掌忽上去，就是一個較小正周期----這是手感上的周期性。我們要確定這一巴掌里面能覆蓋多少個鍵：太少了不行----因為這樣就限制了鋼琴音樂的豐富性；太多了也不行----因為這樣會導(dǎo)致每個鍵的寬度很窄，容易一指頭戳到兩個鍵。就現(xiàn)有鋼琴的排鍵密度，江蘇華星鋼琴電子琴，好多胖紙也會吐槽按不到兩個黑鍵中間去，巴赫這貨貌似就挺胖的…于是巴赫就想，一巴掌里面排12個音很恰當(dāng)，7個白鍵，江蘇華星鋼琴電子琴，5個黑鍵，黑鍵以兩個一組、三個一組，間隔排列在均勻分布的白鍵之間。這是一個很好的排列方式：這使得你一巴掌無論拍在什么位置上，都會拍到一個較小正周期，并且具有視覺上的周期性----鋼琴家很容易一眼就確定每個音的位置。要滿足音的數(shù)量不多不少以及兩個周期性要求，這是較好的排列方式了。電鋼琴不僅能提供專業(yè)演奏鋼琴的音色，還配備管樂、弦樂和其他多種音色。江蘇華星鋼琴電子琴</p><div

style="text-indent:25px">智能鋼琴到底好不好：要說智能鋼琴好不好，我覺得挺好的，當(dāng)然我說的智能鋼琴不是電鋼琴，而是智能原聲鋼琴。為什么我說智能鋼琴好呢，那肯定是因為身邊智能鋼琴與傳統(tǒng)鋼琴、電鋼琴的區(qū)別是什么有人買過，用過，所以才說智能鋼琴好。首先，智能原聲鋼琴，它相當(dāng)于是在一臺傳統(tǒng)鋼琴的基礎(chǔ)上加裝了一套智能系統(tǒng)，結(jié)合了傳統(tǒng)鋼琴和智能鋼琴的優(yōu)點。在外觀、音色和手感上是和傳統(tǒng)鋼琴一樣的，只是比傳統(tǒng)鋼琴多了更多的智能功能，像什么遠(yuǎn)程聯(lián)動，一鍵靜音，自動演奏這些，對孩子學(xué)琴幫助挺大的。特別是前段時間用智能鋼琴上線上課，簡直不要太方便了，不僅較大提高了孩子的練琴效率，在家上課還節(jié)省了去培訓(xùn)機(jī)構(gòu)來回接送的時間，對家長來說也是種解放。江蘇華星鋼琴電子琴鋼琴伴奏時我們用雙手交替的形式，左手彈奏八度低音，右手彈奏柱式和弦。</p><div

style="text-indent:25px">注意擦拭保養(yǎng)方式：為了保證鋼琴的漆膜光亮清潔，應(yīng)經(jīng)常用軟布揩擦表面。如外表有人體脂肪的油印，汗水滴落在鋼琴外殼的油漆面上，都會留下痕跡。時間一久，會形成斑斑污點。要除去油漬、汗邊形成的污點，可用軟布蘸上酒精或經(jīng)過稀釋的洗潔精，在琴面上擦拭后，再用干布擦凈，然后在鋼琴的外表涂上鋼琴高級光亮劑，再用軟布擦拭，您的鋼琴外表會光亮如新。通常可保持一段時間鋼琴的外表不容易粘上油污及灰塵。切忌用**、稀料（香蕉水）等化學(xué)劑擦拭。如果鋼琴弦軸釘和琴弦生了銹斑，有的人會往弦軸何和琴弦上涂抹凡士林或機(jī)油，如果油類從弦軸釘滲進(jìn)弦軸孔內(nèi)，就會給鋼琴調(diào)音帶來麻煩，嚴(yán)重的根本無法調(diào)音。琴弦上的油漬粘到了制音器音頭上、小槌頭上，不但會影響毛氈的顏色，而且制音效果和音色也將變壞。弦軸和弦上的油漬時間一長會粘上灰塵，這樣既不美觀，防銹的能力反而更差。</p><p style="text-indent:25px">現(xiàn)代鋼琴：鋼琴的音域?qū)拸V，現(xiàn)代鋼琴一般為88鍵，可達(dá)7個多八度，音量宏大，音色變化豐富，可以表達(dá)各種不同的音樂情緒，或剛或柔，或急或緩均可恰到好處；高音清脆，中音豐滿，低音雄厚，可以模仿整個交響樂隊的效果，因此有“樂器較好”的稱號。Slide soft system技術(shù)簡稱3S技術(shù)，是立式鋼琴中較好的革新，由日本東洋鋼琴制造株式會社發(fā)明，普通立式鋼琴是通過改變擊弦距離，輕打琴弦來減弱琴音。但使用3S技術(shù)的鋼琴采用與三角鋼琴同樣的工作原理，減少被打弦的數(shù)量來達(dá)到弱音效果。3S技術(shù)可使有效打弦速度達(dá)到普通鋼琴的1.5倍，能夠以不次于三角琴的打弦速度演奏。而且在使用弱音踏板演奏時，絲毫不會影響連擊的速度。安裝有3S技術(shù)的立式鋼琴即使踩上弱音踏板，觸鍵的手感也不會發(fā)生變化。鋼琴對初學(xué)者而言和聲的無縫連接、合理表現(xiàn)是一大難題。</p><div

style="text-indent:25px">學(xué)會在不平的“地上”學(xué)走路。黑白鍵交替彈奏時，由于白鍵的彈奏位置比較靠近鍵盤外，黑鍵靠近鍵盤里面，彈奏下一個鍵事先要準(zhǔn)備的，如白鍵彈奏完后下一個鍵是黑鍵的話，要注意前一個白鍵的彈奏部位要盡量靠近里面一些。順便說一下慢彈很重要，因為不慢彈，由于黑鍵高且窄，會導(dǎo)致不容易觸摸到黑鍵，更何況要有時間事先作下一個鍵彈奏的準(zhǔn)備。由于這回是在高低不平的路上行走，開始時會有手腕的顛簸。一定要注意手腕的放松和協(xié)調(diào)，做好黑鍵和白鍵的手指的支撐點控制手掌的重心不要有大的上下顛簸。這一步也很重要，尤其是需要有在白鍵上平穩(wěn)行走的堅實基礎(chǔ)。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.山東上海華星鋼琴家用鋼琴</p><p style="text-indent:25px">21世紀(jì)市場上的電鋼琴也都是88個標(biāo)準(zhǔn)鋼琴鍵盤，同樣可以彈奏這些鋼琴曲目。江蘇華星鋼琴電子琴</p><p style="text-indent:25px">電子琴因其便捷性和實用性越來越受到人們的歡迎，它的主要原理為琴鍵通過與其對應(yīng)的開關(guān)電路把琴鍵的按壓動作傳至發(fā)音裝置，發(fā)音裝置發(fā)出與該被按壓琴鍵相對應(yīng)的樂音，達(dá)到了演奏的目的。現(xiàn)如今電子琴的琴鍵與琴基座的連接一般采用以下方式：利用鍵盤支架等連接部件將琴鍵固定在電子琴的底殼上。在這種連接方式中，琴鍵在被按壓時，琴鍵與連接裝置之間設(shè)置的彈簧被拉長，同時琴鍵與音階導(dǎo)電膠接觸并擠壓音階導(dǎo)電膠，音階導(dǎo)電膠將信號傳至發(fā)音裝置；當(dāng)取消對琴鍵按壓時，琴鍵在彈簧和音階導(dǎo)電膠的回復(fù)力作用下恢復(fù)至未按壓狀態(tài)的初始位置。江蘇華星鋼琴電子琴</p><p> 企業(yè)業(yè)創(chuàng)建于1985年10月，原為上海華新電子儀器廠，生產(chǎn)電子琴及電子樂器，隨著生產(chǎn)規(guī)模的發(fā)展，到1992年5月成立華新電子電器總廠。2003年12月根據(jù)國家的有關(guān)規(guī)定進(jìn)行企業(yè)改制，將上海華新電子電器總廠轉(zhuǎn)制為上海華新樂器有限公司。 </p> <p> 經(jīng)過近30年的不懈努力，公司目前已發(fā)展成為一個具有完整制造設(shè)備及運(yùn)用高新科技研發(fā)團(tuán)隊的現(xiàn)代化企業(yè)，是中國樂器行業(yè)的開拓者。企業(yè)的主要產(chǎn)品是數(shù)碼鋼琴、電子鼓、MIDI鍵盤、專業(yè)合成器及其他電子音樂教學(xué)設(shè)備。企業(yè)擁有自主經(jīng)營進(jìn)出口權(quán)。在致力于自主品牌并取得驕人的成績外，華新與海外**公司建立了長期的技術(shù)合作與貿(mào)易關(guān)系。這些公司包括**的日本ROLAND、德國THOMANN、美國及日本SUZUKI、法國ARTURIA、美國SAMSON等等。 </p> <p> 30年來華新追求自我系統(tǒng)的完善，以技術(shù)創(chuàng)新為目標(biāo)，以***的質(zhì)量為追求，成就了現(xiàn)今行業(yè)中的地位，并將在未來繼續(xù)創(chuàng)造佳績。 </p> <p> <br /> </p></p><br /><p>文章來源地址:
