Not everyone will dance to the same style of music. Most of the time popping will be done in funk or electro , but not everyone are into that kind of music so lets break it down to the basic. 1st lets break down technique . For a beginner use one technique for one layer of the music. For example. Hitting with back beats ( drum beat) the beat that keep the groove of the song. The next layer sound might be Guitar, base, or what ever sound use isolation with that layer. So the idea here is to match one technique with one layer of music .This is a great way to start to understand your own groove and how you like to dance to a song. The more you work on it the more ideas you can use to express yourself.
