🎭 sounds like JOW-ban; 叫 = shout/call + 板 = beat, so calling the beat to cue the band
叫 — mouth 口 + 丩 (phonetic)
叫 is a phono-semantic compound. The 口 (mouth) radical gives the meaning, since the word involves vocal action like shouting or calling. The right side 丩 supplies the sound, originally depicting twisted cords and used here purely as a phonetic marker.
板 — wood radical 木 + 反 (fǎn, phonetic)
板 is a semantic-phonetic compound. The 木 'wood' radical signals the meaning — a flat piece of wood, i.e. a board or plank. The right side 反 supplies the sound, historically close to 'bǎn/pàn'. Over time it extended to mean any flat panel, and figuratively 'stiff' or 'inflexible'.
