If you've ever seen a street dance performance in person, or on a show like America's Best Dance Crew, then you know it's a huge crowd pleaser. Even those who don't like hop-hop music (myself included) love watching hip-hop dancers. It looks cool and even if you don't plan on performing anywhere, it's a neat skill to have under your hat. There are a few different places you can go to to learn how to street dance and each have their pros and cons.
Local dance studios will often have hip hop and street dance lessons. These are great because you are learning from a professional dancer. it's also a great way to meet other people with similar interests. However, dance studios are known for having some rather expensive lessons so you should opt for a trial package if available to avoid spending too much if it turns out that you don't like the lessons. Street dance lessons at a studio will usually charge per class.
Private dance lessons will usually be done in your own home, or at the home of the instructors. This is a better option for those who don't want to feel pressured to keep up with the rest of the class. Private street dance lessons will also make sure the focus is on perfecting your skills, since there won't be other people to distract you or the instructor. On the downside, private lessons are even more costly that lessons at a studio. Ask if your local studio offers one-on-one coaching, or check Craiglist and newspaper listings. Private street dance lessons are most often charged at an hourly rate.
YouTube is a free and convenient way to learn street and hip-hop dancing. There are many channels established solely for the purpose of teaching hip-hop dance moves. Most of these videos will expect you to bring some knowledge to the table however, so you probably won't get any individual assistance. Even so, you will be able to learn hip-hop dancing for free and on your own time. If you're shy, you might feel more comfortable practicing alone on your own time.
Online dance lessons offer a mix between video instruction and personal assistance. In addition to having a library of intrustional videos that you can complete and revisit at your own pace, you will also have access to a coach or instructor who can answer your individual questions. Most online street dance lessons have a small one-time fee.
