Welcome to the 5Rhythms
The Movement Work of Gabrielle Roth
This might help you dive in and enjoy your first experience in the 5Rhythms

What are the 5Rhythms?
The 5Rhythms comprise a simple movement practice designed to release the dancer that lives in every body, no matter what its shape, size, age, limitations and experience. To find your dance is to find yourself, at your most fluid and creative level. While the practice itself is the essence of simplicity, it has the catalyze deep healing and creative expression.
The primary teaching of this work is: If you put the psyche in motion, it will heal itself.
The five rhythms are flowing, staccato, chaos, lyrical and stillness. They come together to create the Wave, a movement meditation practice. Rather than having steps to follow, each rhythm is a different energy field in which you find your own expression and choreography, thereby stretching your imagination as well as your body. Each rhythm is a teacher and you can expect to meet different and sometimes unknown aspects of yourself as your dance unfolds and your practice of the rhythms deepens over time.
The rhythms are the foundation of Gabrielle’s body of work, a series of healing maps for the body, heart, mind, soul and spirit that provide a lifetime of self-discovery and a path to awakening. The 5Rhythms practice starts you on that journey and is the place to which you will always return.

What happens on the dance floor?
In every class or workshop, there is always a wide range of experience in the 5Rhythms work - from first-timers to certified Wave addicts. In any given class, the teacher will be following the energy in the room. So, while the essential map is one of the five rhythms, the teacher might take the class through the entire Wave or focus on just one rhythm or one facet of a rhythm.
The rhythms themselves are gateways to literally thousands of different movement landscapes. Like the body, they are alive and designed to catalyze the dancer’s movement expression in the moment. You are different every time you walk in the room, so is the group and so is the teacher. Therefore, each class holds completely unique possibilities.

How do I start?
1. Go at your own pace
2. Be responsible for your own body (stay aware of injuries and limitations)
3. Keep your eyes open to stay aware of others
4. Dance barefoot or in dance shoes only - no socks on the floor
5. Move how you feel and stay open to changing
6. Know that everything that is alive has a dance, and your only task is to find and express yours
7. Enjoy yourself! (Excessive seriousness may slow you down)
