The kanji 調 調 is a phono-semantic compound (形声文字). The left side is a component representing words such as "speak" or "discuss" and the right side originally depicted the sound of a "long period of time." Together, they combine to indicate the idea of "speaking and assessing something over a period of time, leading to a conclusion," and also "investigating or arranging to achieve harmony." The combination of elements contributes to its meaning of investigation and adjustment. Over time, the form of the character has been simplified.
