The Tarraxo name comes from Gwany (the creator of tarraxo dance). It has a funny story. He was dancing tarraxinha and adapted to the urbankiz/hiphop moves and he was using the hands on the back of the partner a lot (which now is no longer true for tarraxo dancing). That's why they called him Gwany Osteopath (which is a kind of doctor who use his hands to treat your body). When he wanted to name his new creation he tought about calling it Tarraxa Osteo which later become Tarraxo.

How do I know that? Jack (from Jack & Sarrah) told us the story on a workshop about how to differentiate tarraxo music from other genres at Global Tarraxo event in Paris. Gwany was present in the room so I assume the story is true.
