"Repetition is based on body rhythms, so we identify with the heartbeat, or with walking, or with breathing"

This quote by Karlheinz Stockhausen talks to the power of repetition in music. Repetition is based on body rhythms, which are the natural rhythms of the body. These rhythms are discovered in the heart beat, strolling, and breathing. By duplicating these rhythms in music, we can develop a sense of familiarity and connection with the music. This connection can be both physical and psychological, as the body rhythms are connected with our own physical and emotions. Repetition can also be used to produce a sense of stress and anticipation, as the listener awaits the next repetition to happen. Repetition can also be used to create a sense of unity and cohesion, as the very same rhythms are duplicated throughout the piece. Eventually, repeating is a powerful tool in music, as it can create a strong connection between the listener and the music.
