Swing

Swing, Shuffle, Boogie Woogie,...

In music, the term swing has two main uses. Colloquially, it is used to describe the propulsive quality or feel of a rhythm, especially when the music prompts a visceral response such as foot-tapping or head-nodding. This sense can also be called groove. It is also known as shuffle.

And really, it's just Rhythm, a rhythmic pattern applied to various styles.

Swing is an interpretation of the traditional even eight notes involving alternately lengthening and shortening the first and second consecutive notes.
