琵琶（上房脂下蒲巴反本出西戎胡樂名也釋名云推手為琵引手為琶其皷時為名也說文二字並從玨比巴聲也玨音角）。

琵琶 (The first character is pronounced 房 + 脂 fanqie; the second 蒲 + 巴 fanqie. Originally of the Western Rong, it is the name of a Hu instrument. The Shiming says: 'Pushing the hand forward is pi, drawing the hand backward is pa; it is named after the manner of playing.' The Shuowen says both characters take 玨 as semantic, with 比 and 巴 as phonetic; 玨 is pronounced 角).
