Right phonetic
奏 supplies the full sound zòu with no drift.
奏 itself means 'to present, to play music', but in
揍 it functions purely for sound. The pairing produces a colloquial 'thrash, smack' verb. Same phonetic
奏 also drives
凑 (to gather close) — the two characters are visually parallel and live in the same zòu/còu sound family.
