蔡女昔造胡笳声，一弹一十有八拍。
胡人落泪沾边草，汉使断肠对归客。
古戍苍苍烽火寒，大荒阴沉飞雪白。
先拂商弦后角羽，四郊秋叶惊摵摵。
董夫子，通神明，深松窃听来妖精。
言迟更速皆应手，将往复旋如有情。
空山百鸟散还合，万里浮云阴且晴。
嘶酸雏雁失群夜，断绝胡儿恋母声。
川为净其波，鸟亦罢其鸣。
乌珠部落家乡远，逻娑沙尘哀怨生。
幽音变调忽飘洒，长风吹林雨堕瓦。
迸泉飒飒飞木末，野鹿呦呦走堂下。
长安城边东掖垣，凤凰池对青琐门。
高才脱略名与利，日夕望君抱琴至。

李颀

　　（690？～751？）祖籍赵郡（今河北赵县），长期居住在颖阳（今河南登封西）。唐代诗人。开元二十三年（735）进士。曾为新乡县尉，弃官后隐居“东川别业”。与王维、高适、王昌龄相唱和。以五言、七言歌行和七言律诗见长。其边塞诗格调雄浑奔放，慷慨激昂。如代表作《古从军行》，以豪迈之笔写尽塞外风光，结尾寓意深刻，悲凉沉郁。描写音乐的诗《听董大弹胡笳兼寄语房给事》也较有名，刻画生动，扣人心弦，有较强的艺术魅力。著有《李颀集》传世。《全唐诗》录其诗3卷。

【注释】： 董大，名兰庭，是房琯的门客善弹琴；房给事，姓房，名琯，给事中是官名。商弦、角羽：古琴有五音，依次为宫、商、征、羽。乌珠：在今内蒙古自治区锡林郭勒盟一带。逻娑：今西藏拉萨。 １、蔡女：蔡琰（文姬）。 ２、拍：乐曲的段落。 ３、商弦、角羽：古以宫商角徵羽为五音。 ４、：叶落声，喻琴声。 ５、逻娑：今西藏拉萨市。 ６、东掖垣：房任给事中，属门下省。 ７、凤凰池：凤池，因接近皇帝之故而得此名。
【简析】： 这首诗也是写听琴的，从胡笳十八拍引起许多联想，充满边塞风情和历史回声。以视觉来写听觉，借助许多形象来表达自己的主观感受，是诗中常用的手法。因为诗是呈送房琯给事中的，所以结尾是对他的赞美，题虽云弄（戏）实际是借听琴来称赞房琯，表现了文人的心计。 ON HEARING DONG PLAY THE FLAGEOLET A POEM TO PALACE-ATTENDANT FANG When this melody for the flageolet was made by Lady Cai, When long ago one by one she sang its eighteen stanzas, Even the Tartars were shedding tears into the border grasses, And the envoy of China was heart-broken, turning back home with his escort. ...Cold fires now of old battles are grey on ancient forts, And the wilderness is shadowed with white new-flying snow. ...When the player first brushes the Shang string and the Jue and then the Yu, Autumn-leaves in all four quarters are shaken with a murmur. Dong, the master, Must have been taught in heaven. Demons come from the deep pine-wood and stealthily listen To music slow, then quick, following his hand, Now far away, now near again, according to his heart. A hundred birds from an empty mountain scatter and return; Three thousand miles of floating clouds darken and lighten; A wildgoose fledgling, left behind, cries for its flock, And a Tartar child for the mother he loves. Then river waves are calmed And birds are mute that were singing, And Wuzu tribes are homesick for their distant land, And out of the dust of Siberian steppes rises a plaintive sorrow. ...Suddenly the low sound leaps to a freer tune, Like a long wind swaying a forest, a downpour breaking tiles, A cascade through the air, flying over tree-tops. ...A wild deer calls to his fellows. He is running among the mansions In the corner of the capital by the Eastern Palace wall.... Phoenix Lake lies opposite the Gate of Green Jade; But how can fame and profit concern a man of genius
