Chén Yáng 陳暘 (also written 陳𤾉; conventional lifedates ca. 1064–1128, fl. 1086–1110), zì Jìnshū 晉叔 (variant 晉之 in CBDB), of Mǐnqīng 閩清 in Fúzhōu 福州 (modern Fújiàn). Younger brother of the ritualist Chén Xiángdào 陳祥道 (the Lǐshū 禮書 author). Took the zhìkē 制科 special-decree examination in the Shàoshèng 紹聖 reign (1094–1098); rose to Lǐbù shìláng 禮部侍郎 (Vice Minister of the Ministry of Rites). His Sòngshǐ biography is in juan 432 (Rúlín zhuàn).
Chén composed the 200-juan Yuèshū 樂書 (KR1i0002) while serving as Mìshūshěng zhèngzì 秘書省正字 (Editor in the Imperial Library) during the Jiànzhōngjìngguó (1101) and Chóngníng (1102–1106) reigns and presented it to the throne; with the Huángyòu xīn yuètú jì of 阮逸 and 胡瑗 it is one of the only two surviving Northern Sòng yuè treatises. CBDB id 47561 lists him with alt-name 晉之 and Fúzhōu provenance; index year 1044 is unconfirmed and inconsistent with the Sòngshǐ chronology of his career, so the conventional career window 1086–1110 should be preferred. The Sòngshǐ biography pairs him with his brother as the seminal Northern Sòng ritualists of music-and-rite scholarship.
