發(fā)布時間:2017-08-14 10:30:46音的高低 音的強弱 音的長短 音色(1)音有高低、強弱、長短、音色四種主要性質(zhì),在音樂表現(xiàn)中非常重要,其中以音的高低和長短最為重要。不知道您是否有這樣的體會:對于一首歌,不管您人聲演唱還是樂器演奏,唱的聲音是小是大,也不管您演唱或演奏時用什么調(diào),音的強弱及音色有了變化,但這支歌的旋律依舊??墒牵绻@首歌的音高或音的長短有改變的話,則音樂的感受就會受到嚴(yán)重的影響。可見,對一段旋律來說,音高和音長短的重要性。(2)音的高低決定于物體在一定時間的振動次數(shù)(頻率)。振動次數(shù)越多,音越高;振動次數(shù)越少,音越低。音的強弱決定于振幅(音 的振動幅度)的大小。振幅越大,音越強;振幅越小,音越弱。音的長短決定于音的延續(xù)時間的不同。音的延續(xù)時間越長,音越長;音的延續(xù)時間越短,音越短。而音色由發(fā)音體的性質(zhì)、形狀及泛音的多少等多種因素決定。(3)什么是音色? 音色指音的感覺特性。是音樂中極為吸引人、能直接觸動感官的重要表現(xiàn)手段。發(fā)音體的振動是由多種諧音組成,其中有基音和泛音,泛音的多寡及泛音之間的相對強度決定了特定的音色。人們區(qū)分音色的能力是天生的,音色分為人聲音色和器樂音色。人聲音色高、中、低音,并有男女之分;器樂音色中主要分弦樂器和管樂器,各種打擊樂器的音色也是各不相同的。

Designed to express the nature of Chinese children, the 5 doll-like Frinedlies are symbols of four popular animals-the Fish , the Panda , the Tibetan Antelope , the Swallow and the Olympic Flame . Each of the Friendlies has a Chinese name-Beibei , Jingjjing , Huanhuan , Yingying and Nini. When we put them together , they say Beijing Huan Ying Ni, or Welcome to Beijing ! in English . These lovely dolls show us the Olympic spirit of universal friendship , and they each represent one of the following-the sea , forest , fire , earth and sky . As you can see , their colours have something to do with the 5 colours of the Olympic rings .I really hope you may come to Beijing in 2008 ! Certainly I ll be your company then ! Looking forward to your arrival !Yours ,Li Hua
