Of course, everything needs a certain method. There are six basic steps in tap dancing: straight stroke, forward stroke, backward stroke, sole stroke, heel stroke and toe stroke, as well as some basic steps such as stamping, jumping on one leg and changing steps. Other movements are actually various permutations and combinations of these basic movements. Therefore, Yan Ling suggested that beginners must practice basic skills and then do some systematic training step by step. At that time, you can jump as much as Jim Carrey did in Singing in the Rain!
But if the method is not correct, the knee is easy to get hurt. Because tap dancing mainly depends on the impact resistance of feet on the floor, if the basic skills are not at home, jumping on the hard concrete floor will sprain your knees. Tap dancing should follow scientific methods and practice step by step.
