Dance improvisation is the process of spontaneously creating movement. Development of improvised movement material is facilitated through a variety of creative explorations including body mapping through body mind centering, levels, shape and dynamics (see Laban Movement Analysis), sensory experiences through touch or contact improvisation, and perceptual schema.
Dance improvisation is not only about creating new movement but is also defined as freeing the body from habitual movement patterns. Dancer and singer Michael Jackson combined improvisation in both of those definitions, insisting that he had interest in performing a dance to Billie Jean only if he could do it a new way each time.
Tips for increasing your Dance improvisation
1. Get comfortable. Warm up and stretch. Wear movable clothing. Wear dancing shoes of your choice.
2. Find a space large enough to dance. Move furniture and other obstacles aside.
3. Be alone or just with your parner. Especially when you first start.
4. Get a mirror.A mirror will help you see how you look. If no mirror is available, a glass door or large window can provide some feedback, too. It helps to stand on the more brightly lit side.
5. Put on some music. Something upbeat with plenty of drama and variety is a good place to start. Try many different songs and styles to find what works for you.
6. Become familiar with the time and beat just by walking to the music. As you warm up, vary your steps and start to move your upper body any way that seems to go with the music.
7. Experiment with different ways to move. Arms, hands, legs, and feet are the obvious ones, but don't forget shoulders, knees, head, chest, hips and everything else. Notice what looks good and what feels good. Notice what works with your music.
8. Work up to dancing with your whole body. If you're extending a hand, for instance, follow with your chest and head and use your legs. Unless you intend to keep something motionless, you'll just end up looking stiff.
9. Try moving slowly between a series of poses, with or without slow music. Think about the shape and posture of your whole body.
10. Move to the music and do the obvious. Pantomime the words. Get bigger when the music gets louder; get faster when the music gets faster.
11. Put spirit, conviction, and enthusiasm into your dance. Shake, turn, move with the music. Intensity doesn't necessarily mean speed, though. A slow motion can be every bit as intense and deliberate as a quick one.
12. Notice moves and ways of moving, whether in other dancers or just in those around you. Dance is an amplification of body language you already know. Does your music call for you to puff up your chest and strut, or shrink sadly away?
13. Watch other dancers for moves and ideas. Also watch anybody else moving. Martial artists, figure skaters, actors on a stage, soccer players, and children can all suggest ways to move.
14. Take dancing lessons in different styles to learn motions, then mix them together. This is your own creation, so there's no reason that elements of belly dancing and ballet can't blend.
15. Try dropping in unexpected elements once you get the hang of it. Step on a beat when the music is still, subdivide the beat, change direction mid-measure or mid-phrase, and occasionally do something a bit contrary to the mood of the music.
