style="text-indent:25px">頻率排列和琴鍵排列：說鋼琴一共有88個鍵，它們各自的頻率組成一個等比數(shù)列，比例系數(shù)是2開12次方，即2^(1/12)，中音A(左起第49個鍵)的頻率規(guī)定為440Hz，于是所有88個鍵的頻率都確定了?，F(xiàn)在就有一個問題，為什么是等比數(shù)列而不是等差數(shù)列？從“十二平均律”這個名字看，在較低頻率和較高頻率之間均勻分布88個音，也應(yīng)該得到一個等差數(shù)列才對。這里有兩個原因。靠前個原因，也就是我覺得較重要的原因，是取決于人的聽覺。人耳分辨兩個音的高低，靠的是兩個音之間的頻率比例，而不是頻率差值。比如說，一個正常人可以清楚的區(qū)分50Hz和55Hz，但卻很難區(qū)分5000Hz和5005Hz(也許莫扎特可以，但是莫扎特是大神，大神是不具備參考意義的…)。這就意味著，如果鋼琴上音的分布是等差數(shù)列，那么越到高音，你就會發(fā)現(xiàn)兩個音越難以區(qū)分。這不是我們想要的。上海兒童電子琴報價彈琴前先洗手，保持琴鍵清潔；勤剪指甲，過長的指甲會劃花琴鍵。</p><div

style="text-indent:25px">鋼琴的特點：（1）鋼琴的低音區(qū)還有比大字二組的A更低的若干琴鍵。這樣寬廣的音域，只有管風琴可與其相比，超出了任何其他樂器。（2）音量變化幅度巨大。音量是指聲音的強度、力度。鋼琴既可發(fā)出十分微弱、人耳剛剛能聽見的弱音（ppp），也可發(fā)出宏亮有力、震撼人心的強音（fff),以及處于極弱極強兩者之間的各個力度層次的聲音。并且，這些不同的力度都是可以隨鋼琴家的心之所欲彈出的，這又使鋼琴勝過包括管風琴在內(nèi)的所有單件樂器。（3）較理想的多聲樂器。由于鋼琴使用十二平均律，使音樂的轉(zhuǎn)調(diào)、復調(diào)、和聲獲得極大的自由。鋼琴家借助踏板的作用，用他們經(jīng)過訓練的雙手，可以在鋼琴上彈奏出無限豐富的縱向、立體組合。手風琴、吉他也是多聲樂器，但是他們在樂音組合的多種可能性上卻遠遜于鋼琴。</p><p style="text-indent:25px">鋼琴的音色表現(xiàn)力及功用特點：眾所周知，音色是樂器及人聲客觀物體振動在主觀聽覺上的反映。音樂藝術(shù)的表現(xiàn)方式主要分器樂與聲樂兩大類，人的嗓音和樂器發(fā)出的音品不同，即存在音色的不同，這同許多因素相聯(lián)系。樂器音質(zhì)的差別同發(fā)音體的形狀、構(gòu)造、材料的質(zhì)量、成分、彈性以及激發(fā)振動的方式等有關(guān)。研究影響音色的性質(zhì)，除了基頻成分外，還可通過觀察泛音列、頻譜、示波器波形等。以鋼琴琴弦為例，琴弦振動不是一個簡諧振動而是一個復諧振動，琴弦被擊(激)發(fā)后，琴弦上產(chǎn)生許多波腹和波節(jié)的復諧波，整條琴弦的振動又包含著各分段振動，這就是所謂的鋼琴階波(泛音)特質(zhì)。所以，試彈奏鋼琴的中、低音區(qū)，常明顯地聽到基音和一系列諧音同時發(fā)響的復合音。須知，樂音的頻率是由基音所定，音色主要是由泛音的多少及其強度決定，換句話說，基音頻率決定音高，泛音或諧音的多少及其強度決定音色。緊繃在鋼琴弦列中的200多條琴弦與音板、框架間的耦合，是鋼琴音色特性的“原始”條件。鋼琴可懸掛處，用紗布包裹上除蟲劑，然后懸掛起來，這樣就可以有效地預防和殺滅各類蟑螂和蛀蟲。</p><div

style="text-indent:25px">鋼琴黑白鍵寬度是多少：我國鋼琴標準規(guī)定：88鍵鋼琴總體寬度為1215—1235毫米;白鍵前段長度為50—52毫米，黑鍵(鍵桿上的構(gòu)件)長94—96毫米;黑鍵(上部)表面寬度為9.5—10毫米，前端高度距白鍵表面為11.5—12毫米。白鍵與黑鍵統(tǒng)稱為鍵桿，白鍵稱為白鍵桿，黑鍵稱為黑鍵桿，它們又被稱為琴鍵、琴首、毽子，是鋼琴的彈奏部分。白鍵與黑鍵在鋼琴上有多少，是隨著鋼琴的音域范圍與琴弦的音名而確定的。鋼琴（意大利語：pianoforte）是西洋古典音樂中的一種鍵盤樂器，有“樂器”的美稱。由88個琴鍵（52個白鍵，36個黑鍵）和金屬弦音板組成。盡量不在鋼琴上放置花瓶、相框等物品，會容易與鋼琴產(chǎn)生共震。蘇州電子琴價格</p><p

style="text-indent:25px">鋼琴有什么種類：1、立式鋼琴由于三角鋼琴比較占用空間，人們就想把三角鋼琴豎立起來使用。這就出現(xiàn)了早期的立式鋼琴。所以，三角鋼琴要比立式鋼琴早得多。立式鋼琴價格便宜，占用空間小，成為愛好者的購買對象。立式鋼琴采用一種琴弦交錯的設(shè)計方案，有效地節(jié)約了高度與厚度。在此之前的立式鋼琴高度達2.4米?，F(xiàn)在的只有1-2米高。2、三角鋼琴三角鋼琴是用于大型演出或?qū)I(yè)人士的一類鋼琴。音樂會所用的大三角鋼琴是樂器中的龐然大物，有9英尺長，較重的可達600公斤。3、自動鋼琴自動鋼琴在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。拉赫瑪尼諾夫、德彪西、**、格什溫、R·施特勞斯都曾為這一樂器寫作樂曲，制成紙帶，供演奏使用。數(shù)碼鋼琴什么牌子好質(zhì)量也好</p><p
