乐器人类通过演奏乐器，借以表达、交流思想感情。对乐器的界定,音乐界和乐器学界有不同看法。音乐界认为,用于音乐的发声器具才是乐器;乐器学界则通常将许多非音乐领域中的发声器，如古代战争中的鸣金击鼓、宗教中的祈祷诵经、婚丧中的礼仪信号、商贩招揽的信号器等，也视为乐器

　　参考译文:

　　A:玛丽，我记得你弟弟对学习乐器很感兴趣。他决定什么时候开始学了吗?

　　B:还没有。这些天他有点忙。另外，他也没想好要学习哪种乐器。长笛和吉他他都喜欢，所以不知道该选哪一个了。

　　A:跟他说就随便选一个好了，另外一种乐器可以以后学。

　　B:没错，我就打算这样跟他说。嗯，你小提琴课上得怎么样了?

　　A:挺好，我刚学了首协奏曲，不太好拉，需要时常练习才行。你的钢琴课怎么样了?

　　B:哦，也是越来越难了。上周学的一首摇篮曲还相对简单点，但是这周学的奏鸣曲就非常难了。

　　A:其实，要提高弹奏技巧，除了跟随老师学习，还有另外一个好办法—多听听*演奏家的演奏。
