台灣的客家族群是一個色彩鮮明、特立獨行的族群，處處保留獨特的客家文化特色。客家文化中客家民謠是最獨特的一環，民謠本是台灣民間音樂重要的源泉，各地的民謠都有其特殊的背景與風格，客家民謠經過長期的洗鍊與發展，也有其獨特的調式、結構與風味，具有無比的價值。從客家民謠涵蓋與流傳的廣遠來分析，山歌在整個客家文化來說，佔有最重要的一環。客家民謠俗稱「山歌」，山歌是客家文化的精華與代表，它唱出了客家人的勤勞與耐苦，也象徵著客家人的堅忍與純樸。長久以來，山歌一直是客家人最重要的精神食糧，雖然沒有宮廷音樂的高貴與華美，但它卻代表着客家人秉性的純樸與真情。詞淺意深的客家山歌不僅是客家傳統文化、民族音樂的一塊瑰寶，而且是一項最真、最美的的藝術，所謂「好韻能興千百業，好歌能解一身勞」正是客家山歌的本質。
數百年來，在客家人移墾台灣披荊斬棘的艱苦過程中，客家山歌一直佔有很重要的地位。它安慰了客家人離鄉背井遊子們落寞情懷，它也流露出客家民族愛鄉愛國的憂懷心聲，它更傳達了客家男女樸實心靈與對各種深情的渴望。
本文旨在研究客家山歌的文化內涵，分析客家山歌之起源、種類、歌詞，並探討台灣客家山歌沒落之現象，詮釋山歌有助於客家話與客家文化之傳承；由山歌的推廣擴大到，謀求台灣客家文化的全面復興。
