Visit the Salsa Boot Camp website (see Resources). It offers online bachata classes that you can take with or without a partner. You can learn them on your own, but it will be easier with a partner, especially if you are female because the man leads in this dance.
Sign up for a membership at Salsa Boot Camp. You can try it free for three days. If you want to remain a member, you have to pay for either a monthly or quarterly membership. There are five online bachata classes offered by Salsa Boot Camp.
Do the "Beginner Bachata Dance" lesson to begin learning bachata online. You will learn the basic steps that make up the bachata. If you are learning without a partner, this will be the easiest lesson to complete.
Move onto the "Intermediate Bachata" lesson once you have mastered the basics in the beginner's lesson. This lesson will be easier with a partner as you will be learning some of the steps that are unique to the bachata, such as the Cuban hip movement.
Finish your online bachata lessons with the "Advanced Bachata Dance" lesson. You will have difficulty mastering this lesson without a partner as there are some spins and dips in it. You can watch the "Bachata Rueda Videos" lesson to see dance professionals dancing the bachata and compare your skills to theirs to see what you need to work on. Additional lessons are available in the "Bachata Dance: Int/Adv" lesson as well.
