Advanced dancers know how to work in any level class. If the material is simpler, they will work on emotional texture, refining their lines, sustaining movements a little longer. They’ll change a shuffle to riffle, a heel to a toe, try different stylizations with each repetition of the combination. They will make the class their own.
Less advanced dancers in the same situation will say the class is too easy, that they already know this, then proceed to not give their full effort because the class is below their ability level.
Smart dancers will ask for ways they can challenge themselves more if they need some guidance. They may respectfully ask if they can try the class that is a level higher in addition to the class they are placed in. Maybe the teacher isn’t seeing all they are capable of, or maybe the dancer takes the extra classes and works up to the level they desire to be dancing at.
Dancers who get it will show up, be present, ask specific questions and enjoy the process.
