The speeches of some people reach us as heavenly music. With some people under certain situations, every second of listening to becomes a torture.
People don't realize that the art of talking is not simply that of a manipulation in meanings. When speaking, people become musical instruments. The expression "it is music to my ears" is a compliment for those who excel in this art of speech. It is not only a metaphor. It is a very accurate description of what is actually happening.
The art of speech is not unidirectional. While listening to others, people become musical instruments themselves. By immersing ourselves in the flow of words, we can resonate to what is being said, magnifying and sometimes even going beyond the original intent and scope of the speaker.
Thus, without holding a flute or sitting before a piano, we can train ourselves as musical instruments, as we go through the usual rounds of everyday life.
