Basically, music is the soul and heart of humans, the source for soothing the mind, and the universal language. Listening to music is virtually a state of mind. Listen to musical notes and how they connect each other, leading to a critical thinking process. If it is jazz, then improvisations are spontaneously carried out, virtually without thinking, representing a feeling of freedom based on mood and rhythm.
