Any type of dancing is great fun and is a brilliant social asset and can give you access to a whole new range of friends. Dancing regularly reduces stress & risk of Alheimer's Disease, helps keep you fit, improves your coordination whilst building your confidence. It’s a partial cure for depression too. Partner dancing, in particular, helps you to interact with other people & it’s such a great way to break the ice when meeting a potential new friend. Partner dancing can even be a tool to help to end racism &/or a long-standing war as may be seen in the video below.
All forms of partner dancing are about 2 or more people moving together in harmony with the music. It therefore makes sense to learn to understand something about the rhythm of the music in order to dance well with musical interpretation. If you cannot synchronise with your partner you find yourselves treading on each other’s feet & bumping into each other. If you & your partner move successfully together, but are not in time with the music, you may feel comfortable, but it still would not look good.
