英語(yǔ)聽(tīng)力：告訴你一生必知的事16：音樂(lè)的起源
Many people love music, but what is it? Generally, music is an art form in which the medium-sound is organized in time. The development of music among humans must have taken place against the backdrop(背景)of natural sounds, such as birdsong and the other sounds for animals to communicate.
許多人喜愛(ài)音樂(lè)，那么究竟什么是音樂(lè)呢? 一般來(lái)講，音樂(lè)是指一種將聲音按時(shí)間組織起來(lái)的藝術(shù)形式。音樂(lè)在人類中的發(fā)展最初源自于對(duì)鳥(niǎo)叫以及其他動(dòng)物用于交流所發(fā)出的聲音的一種模仿。
Music can be divided into genres(流派) and sub-genres(分支)，although the dividing lines and relationships between music genres are often subtle(模糊的), sometimes even controversial. However, just as the saying goes "one man's meat is another man's poison", no matter what kind of genre one likes, the important thing is that he can get satisfaction from it.
音樂(lè)可以被劃分為不同的流派或分支，盡管在一定程度上這種劃分的界限通常比較模糊，甚至有時(shí)存在爭(zhēng)議。然而，俗話說(shuō)得好，"蘿卡白菜，各有所愛(ài)"，無(wú)論一個(gè)人喜歡哪種流派，重要的是他可以從該種音樂(lè)中獲得滿足感。
In general, music is composed and performed for many purposes: aesthetic(有關(guān)美的，審美的) pleasure, religious or ceremonial purposes, or just as an entertainment product for the marketplace.
通常，音樂(lè)的創(chuàng)作以及演奏會(huì)出于不同的目的，如審美享受、宗教或慶典的目的，或者僅僅作為一種大眾的娛樂(lè)手段。
