We tend to tune out the noise of our lives in order to concentrate on the tasks at hand. In fact, we may get so used to a particular sound that we don’t notice it until it’s gone—like a television that is turned off, or traffic that stops outside your home, or your neighbor’s lawn mower or stereo that is suddenly silent.
We notice when it starts, we intentionally shut it out, and then notice it once again when it stops.
Everyone who hears has a healthy serving of what is called musical intelligence. It isn’t limited to actual music, however—it is our recognition and understanding of the pitch, tone, quality, length, volume and source of the sounds around us.
