Music is the art of vibrations. Sensed by a listener's ears and sometimes chest, their unconscious mind analyzes the frequencies and imagines harmony, the story told by the evolving relationship of consonance and dissonance. Empathizing with an imagined moving body, they experience rhythm. Moving their body in this way, the listener can create dancing, and when multiple people do this, create community. Music can also contain lyrics. Music can be created by individual people or bands. One term for a unit of music is a song. Alternative weekend activities include making visual art and sucking the monkey.
