The word groove is originally a slang term that originated in jazz music and more specifically in swing at the end of the 1930s. This is known as an embellishment phenomenon. The musicians of the time were looking for a form of rhythmic suppleness. By skilfully articulating the three-beat measure, they created a swing that is easily identifiable today. Over time, the expression “groove” has broadened. It is obvious that this spirit of rhythm has existed, exists or persists in other music.
