The kanji 鼓 is a phono-semantic compound (形声文字, けいせいもじ). The semantic component (meaning) is "壴", which originally depicted a drum stand. The phonetic component is "支" シ (shi), which provides the sound. The combination of these components creates the kanji for "drum" and represents the idea of creating sound using a drum.
