With so many different styles of Blues Music, there are also many different styles of Blues Dance.
The swing dance revival in the 1980s-1990s brought on the desire to resurrect and research the roots of the early 1900s swing-era dances to give dancers a full understanding of the dance. The same is true to for the blues dancers. Just like there are several forms of swing dance, there are several forms of blues dance. The biggest difference stems from the type of music being played. Fast, slow, upbeat, sad, happy and sassy.
No matter what style of Blues Dance you dance, they all should maintain a "Blues Aesthetic":
• Athletic stance and grounded movement characterized by the weight being shifted to the balls of the feet, the knees bent, the hips pushed back, and the chest forward. Similar to a "ready stances" of a football player, wrestler or someone dribbling a basketball.
• Rhythmic movement. Your entire body should show the beat of the music. No matter if it is your feet, hands, chest, or hips, each part emphasizes the beats and pulses.
• Improvising is essential since each dancer brings their own feelings and emotions to the dnace floor. Whether it is between dancers or on their own. The dancers show what they hear in the music and portray it in their body movement.
While maintaining its aesthetic of its own throughout the history of African dances in America, Blues dance has been researched and also gained interest across the U.S. and the world.
