The term 'slow musical movement' is often used to describe a type of musical composition that is characterized by a slow tempo. The term is derived from the Italian word 'ADAGIO', which translates to 'at ease'. ADAGIO is also a musical term that is used to indicate a slow tempo, usually between 60 and 80 beats per minute. It is often used in classical music, but can also be found in other genres such as jazz and pop.
