style="text-indent:25px">鋼琴即興伴奏是一門綜合性實踐性很強的學科，不僅是高等音樂教育專業(yè)的必修課，也是一種創(chuàng)作與表演相結合的學科。彈奏者對伴奏類型的駕馭能力很大程度上影響著鋼琴即興伴奏的水平。恰到好處地選配伴奏類型，以及創(chuàng)造性地設計與應用伴奏類型，對一首鋼琴即興伴奏歌曲是否成功起到“定型”的作用。因此，伴奏類型的合理運用就成了鋼琴即興伴奏中需要掌握的一個方面。一首樂曲選擇了合適的伴奏類型，能使作品的內容和藝術形象得到更準確、更生動的展示。伴奏類型是整個鋼琴即興伴奏的骨干，對表現(xiàn)歌曲內容、渲染藝術氣氛起到重要的作用，不同的伴奏類型可以塑造不同的音樂形象，而不同的音樂同樣需要多種伴奏音型來塑造。歌曲的體裁、風格不同，即興伴奏的類型就要跟著改變。上海買什么鋼琴鋼琴鋼琴可以用大螺絲從木箱外面擰到鋼琴背面的支架柱上。</p><div

style="text-indent:25px">鋼琴的社會影響：鋼琴之所以成為樂器大家族中的“較好”，是人類的精神文明及科技文明的發(fā)展所賦于它的，鋼琴作為樂器的出現(xiàn)，是人類社會生活的需求，鋼琴的發(fā)展更從一個側面反映了人類社會精神生活不斷發(fā)展的狀態(tài)。鋼琴作為物質基礎，為音樂家的創(chuàng)作提供了條件，音樂家創(chuàng)造發(fā)展的鋼琴文化又促進鋼琴結構功能的進一步成熟。由此我們說鋼琴是鋼琴文化的不可分割的一部分，了解鋼琴、認識鋼琴，也就成為了一個音樂人認識鋼琴文化的必須了。通常人們認為鋼琴有近300年歷史，即1709年由意大利制琴大師B·克里斯托福里所創(chuàng)制的現(xiàn)代鋼琴的前身。在以后的200多年，又不斷改進完善，方成為我們看到的現(xiàn)代鋼琴。然而，鋼琴的整個演變過程可以追溯到600多年前，即現(xiàn)代鋼琴出現(xiàn)之前，鋼琴已存在了300多年，我們稱這一階段的鋼琴為古鋼琴?，F(xiàn)代鋼琴的前身只是1709年古鋼琴質的發(fā)展與飛躍。若沒有古鋼琴所發(fā)展的“量”的積累，也就不會產(chǎn)生1709年古鋼琴“質”的飛躍。</p><p style="text-indent:25px">國內市場上能夠買到的“電鋼琴”（數(shù)碼鋼琴）大體分為一下幾種：1、假“數(shù)碼鋼琴”，玩具琴，其實就是電子琴或電腦上用的玩具鍵盤，價格數(shù)百元。這一類，不用我提醒，你也不會買。2、雜牌數(shù)碼鋼琴，其實也就是劣質電子琴，較多加上鋼琴的外觀，手感就是玩具電子琴的手感，音色也就是廉價電子琴的音色，價格數(shù)百元至三千元。這一類有些唬人，不過你只要親自彈一個鍵就會立刻識別出來了，當然這一類也一定不能買；3、國產(chǎn)正牌中低檔數(shù)碼鋼琴，具有鋼琴的外觀，具有力度鍵盤（配重或不配重），手感接近鋼琴的重量，但感覺不同（因為沒有擊弦機），具有鋼琴音色（進口或國產(chǎn)音源），價格2000-5000元。這一類琴里有好的，可以購買。鋼琴濕度對音色、使用壽命等的影響很大。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽K60鋼琴電鋼琴,鋼琴"

style="text-indent:25px">頻率排列和琴鍵排列：當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，耳朵的限制只能導致越到高音區(qū)，頻率差越大而已。但是從數(shù)學的角度，我們可以證明這些音的分布必須是等比數(shù)列。這也就是我認為的第二個原因。我們希望琴鍵的排列具有周期性，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，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，7個白鍵，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。鋼琴共振空間三角琴的共振腔結構合理、空間足夠，這使三角琴能發(fā)出更大的聲音。上海買什么鋼琴鋼琴</p><p

style="text-indent:25px">電鋼琴的優(yōu)勢：1、免調律，省心又省錢：大家都知道，電鋼琴是一種電聲樂器，它的每個音色都是來源于鋼琴音色采樣，并不會隨著時間而發(fā)生變化。所以電鋼琴不需要進行調律，也省下了昂貴的調律費用。2、可靜音，不擾民：大部分人在剛剛開始學琴時，往往彈奏出的音樂都不是很好聽，此時努力練琴的行為，在鄰居那里可能就是制造“噪音”。而電鋼琴可以接耳機，做到靜音練習，即使是深夜，也可以讓你達成肆意揮灑彈琴熱情的心愿哦。3、易搬運，輕松更換練琴地點：立式鋼琴的重量一般在200公斤以上，三角鋼琴的重量一般在300公斤以上，搬運起來十分不方便。而電鋼琴的重量則是傳統(tǒng)鋼琴的十分之一，可以輕松搬運，對于經(jīng)常移動琴的用戶實在是十分方便。安徽K60鋼琴電鋼琴</p><p
