class="box"><p><p 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，福建買一臺鋼琴兒童電子琴，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。現(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，也應該得到一個等差數(shù)列才對。這里有兩個原因?？壳皞€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，福建買一臺鋼琴兒童電子琴，福建買一臺鋼琴兒童電子琴，你就會發(fā)現(xiàn)兩個音越難以區(qū)分。這不是我們想要的。鋼琴它不耐碰撞，受到碰撞，輕則影響美觀。福建買一臺鋼琴兒童電子琴</p><div

style="text-indent:25px">鋼琴的音律特點：鋼琴及其音樂發(fā)展之迅猛，藝術(shù)表現(xiàn)之豐富、完美是與應用十二平均律分不開的。鋼琴的誕生時期，正值巴赫在古鋼琴上率先倡導并推行這種律制的時期?，F(xiàn)在十二平均律己被世界所公認，它以簡捷、實用的特點，以其科學嚴謹?shù)挠嬎愠蔀殒I盤樂器及其他樂器固定音高的標準。十二平均律有著與純律、五度相生律律制不可替代的特點，雖然它較自然逍音音列略有出入，然而其勻整性(即一個八度內(nèi)十二等份的平均劃分的半音律制)足以使我們靈活方便地轉(zhuǎn)調(diào)，這為創(chuàng)作和演出音樂藝術(shù)佳作提供了先決條件。從這點上說，沒有鋼琴的十二平均律作為先導，音樂藝術(shù)的創(chuàng)作和表演就會受到限制，也不可能會產(chǎn)生那么多不同風格、體裁、調(diào)式和內(nèi)涵深刻的音樂作品。沒有十二平均律，音樂的創(chuàng)作就會單調(diào)，甚至容易枯萎。有關(guān)這部分的內(nèi)容，我們將在“鋼琴凋律” 的章節(jié)著重討論?？傊?，鋼琴的音律為鋼琴在表達音樂動機、音樂思維、音樂理論及其創(chuàng)作實踐等方面鋪平了寬敞的道路。福建買一臺鋼琴兒童電子琴琶音包括24個大小調(diào)琶音跟屬7減7琶音。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="福建買一臺鋼琴兒童電子琴,鋼琴" src="https://tyunfile.71360.com/WaterMark/UploadFile/huaxinyueqi/637406038128658470/6306127.png"></div><p style="text-indent:25px">白鍵彈好后就能彈好黑鍵好像是順理成章的事。其實不是想象那么簡單的。白鍵上的彈奏好比在平地走路，而夾雜著黑鍵后彈奏則是在不平的路上走路，就像幼兒學會平地上走路后，經(jīng)常要在不平的路被拌住或踩空摔倒一樣，對初學者依舊是困難的。黑鍵加入后帶來的較初的困難有：1、黑鍵的觸覺和白鍵不同，更由于黑鍵較窄，不但觸覺不一樣，黑鍵難彈到甚至較難碰到的。2、黑鍵高出白鍵，彈奏時視覺上和已習慣的白鍵（平地）不一樣，視角的錯覺造成誤碰和誤彈。所以觸覺和視覺上的不同不熟悉黑鍵時，黑鍵觸摸也是有困難的。</p><p style="text-indent:25px">鋼琴較容易損壞的幾個方式：錯誤鋼琴擺放位置：1、靠近經(jīng)常開啟的門窗鋼琴的材料主要是木材，受氣候的影響極大。熱、冷或干、濕的變化會導致鋼琴的琴板、框架等部位收縮或膨脹，甚至使鋼琴內(nèi)部的金屬零件及毛氈等部件生銹、蟲蛀而導致松動、走形，影響彈奏。因此擺放鋼琴的時候，使它遠離經(jīng)常開啟的門窗，可以靠近一面墻(較好是內(nèi)墻）。遠離暖氣、壁爐，避免空調(diào)直吹、陽光直射、遠離洗手間、及廚房油污。2、放到不夠平整的地板上鋼琴的重量大致如下。尺寸：立式/鋼琴三角鋼琴如果地板的強度不夠，就很容易發(fā)生意外事故。因此，請把鋼琴安放在牢固的地板上。此外，如果地板傾斜，或地板有高低差，則鋼琴的放置就會不穩(wěn)定，這對鋼琴的功能也沒有好處。請把鋼琴安放在水平而平整的地板上。鋼琴長時間放在干燥的環(huán)境里也會造成弦軸板木材的收縮。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="福建買一臺鋼琴兒童電子琴,鋼琴" src="https://tyunfile.71360.com/WaterMark/UploadFile/huaxinyueqi/637406002735680028/8464835.png"></div><p style="text-indent:25px">琴套注意事項：鋼琴在銷售時均配有一塊琴鍵罩布。罩布的質(zhì)地一般都選用比較厚的毛織品。但是如果在鋼琴使用后習慣蓋上琴蓋的，沒有必要再放一塊琴鍵罩布。因為彈完琴后鍵盤上會有一些手汗，蓋上罩布后，罩布起到吸潮的作用，很少有人常常把罩布拿出去曬一曬。長期下去罩布的潮氣勢必導致鍵孔受潮膨脹，鍵皮便輕易開膠。這是弊大于利的事。不宜提倡。一般建議使用蕾絲、全棉、或者絨布的琴罩即可。也有些人購買了鋼琴后，為了省事，把包裝鋼琴用的塑料罩套在上面，或在鋼琴上蓋上一塊塑料布，這種做法不可取。塑料布或罩子使空氣不暢通流暢，琴底下的潮氣進人琴體內(nèi)，鋼琴長期在這種情況下，受潮的情況越來越嚴峻，輕易導致內(nèi)部機件的不靈活，音色發(fā)悶，金屬件生銹。外觀油漆失去光澤，勢必影響鋼琴的使用壽命。相較于傳統(tǒng)鋼琴，電子鋼琴的音色過于單一，缺乏個性化的表現(xiàn)。福建買一臺鋼琴兒童電子琴</p><p style="text-indent:25px">數(shù)碼鋼琴雖然是由近代電子琴經(jīng)40多年的歷史發(fā)展而來的，但它并不是電子琴。福建買一臺鋼琴兒童電子琴</p><p style="text-indent:25px">與鋼琴區(qū)別——價格：價格是大部分家長較關(guān)心的因素之一，因為這涉及到家長的投資風險，我們知道有很多家長在購買了價格不菲的鋼琴后，因為孩子不能堅持而放棄了鋼琴的學習，鋼琴在家中成了一件昂貴的擺設，這也是一些家長在孩子學習了相當長的一段時間后，家長卻仍然不能夠下決心購買鋼琴的較重要的原因。21世紀以來市場上能稱得上真正意義的電鋼琴在3000多元到6000多元之間，當然也有更貴的，但是作為家庭使用的話，我們只對這個價格范圍進行討論。普通鋼琴的價格大多數(shù)都在10000元以上。福建買一臺鋼琴兒童電子琴</p><p>
