The kanji 鼓 generally represents "drum" or "to drum." It encompasses the idea of a musical instrument played by striking a surface to produce a rhythmic sound, and by extension, the act of drumming itself. It implies a sense of rhythm, beat, and the creation of sound through percussion. The character can also relate to themes of encouragement, excitement, or stirring up emotions, metaphorically similar to the way a drum can rouse people.

The kanji 鼓 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is a part meaning 音 (oto, sound) and the right side is 支(shi, branch) as a phonetic component, so the sound is similar to the phonetic component 支. Originally, the character depicted a drum and the hand striking it. It was created by combining the elements of “wood” (or the frame of the drum) and a hand with a drum inside of it to depict the act of drumming. Over time, the form has evolved but the core meaning remains. The phonetic component helps indicate the sound of the word.
