‘弦乐’ literally means ‘string music’ and refers collectively to musical instruments that produce sound by vibrating strings—such as violins, violas, cellos, and double basses. The character 弦 (xián) means ‘string’ (as on a musical instrument), while 乐 (yuè) means ‘music’ (not the homophone lè meaning ‘joy’). Together, they form a compound noun denoting either the category of string instruments or the ensemble section in an orchestra dedicated to them.

This term is commonly used in classical music contexts, concert programs, orchestral descriptions, and music education. It’s rarely used for solo performance unless specifying instrumentation (e.g., ‘弦乐四重奏’ — string quartet). Unlike general terms like ‘音乐’ (music), ‘弦乐’ emphasizes timbre, technique, and ensemble function—not genre or emotion. It appears in formal and technical discourse rather than casual speech, and is almost never used metaphorically or outside musical contexts.
