唐代，是中國音樂發展上極輝煌時期。唐代不僅承襲前代傳統的音樂，且因國勢強盛，交通發達，與異域頻繁的往來，異地的樂曲與樂器傳入中土，經過融合與創新，因此，唐代音樂亦呈現多采多姿的異國風貌，甚至擴大了音樂與文學的領域，在唐代，羯鼓即具有此特殊性。羯鼓，屬敲擊樂器，來自外夷，盛行於開元、天寶年間，唐朝時，很多人喜愛且擅長羯鼓，唐玄宗便是其中之一，玄宗認為羯鼓是八音的領袖，其它樂器不可與之相比，唯在現今中國的音樂領域中，它卻是令人陌生的樂器名稱。事實上，此樂器在唐代音樂文學史上曾佔有一席之地，不僅有專門的《羯鼓錄》論著，且受到詩人的歌詠。是故本文試圖論述羯鼓之來源、形制、音色，進而提出專書、人物事蹟及詩作，藉以彰顯其所獨具的時代價值。
