由四组成的

The string quartet is that the instrument being that two is composed of the violin , a handful viola and a handful cello from four pieces of stringed instruments performs combination , their tone colour both unite and be rich in change, be expert in weave the body and refined exquisite lingering charm, four pieces of instruments have and the expressive power big and powerful equally , accord with thought of four west music middle parts habit at the same time, this combination becomes chamber music therefore, being hit by the have most typical ensemble of two or more instrumentalists , each playing one part form, Also become a composer express music thought having imitates a means deep and individuation most .

弦乐四重奏则是由四件弦乐器——两把小提琴、一把中提琴和一把大提琴——组成的乐器演奏组合，它们的音色既统一又富于变化，以细腻的织体和精妙的韵味见长，而且四件乐器均具有强大的表现力，同时又符合西方音乐中四个声部的思维习惯，因此，这种组合成为室内乐中最具代表性的重奏形式，也成为作曲家表达最深刻和最个性化音乐思想的有效手段。文章分析室内乐与弦乐四重奏的基本内容及关系，讨论弦乐四重奏的发展概况，最后探讨了弦乐四重奏的"民族化"及未来发展趋势。
