吹奏
すいそう · suisou · JLPT N1 · noun
instrument
吹 — mouth 口 + lack/yawn 欠
吹 is a semantic compound. 口 (mouth) shows the action involves the mouth, while 欠 depicts a person with an open mouth exhaling or yawning. Together they vividly suggest blowing air out, the core meaning 'to blow.'
奏 — hands 廾 lifting offering 夭 + 丰 (sheaf)
Originally a pictograph showing two hands respectfully presenting an offering or sheaf upward, often interpreted as presenting music or tribute to a ruler. From this ceremonial sense it came to mean 'to play (music),' 'to present (a memorial to the throne),' and by extension 'to achieve' or 'accomplish.'
