When I was talking to the mother of a dancer.
The New tap dancer did not understand all the language of tap .
So , if anyone did not understand Kathleens answer...
it breaksdown like this:She said Hop ,Shuffle, Step ,Toe Grind ,Brush Step.
Lets take them by themselves
Hop: A jump into the air on one foot: With the weight on one foot and the free foot in the air in any direction, flex the knee of the supporting foot; spring into the air and land on the same foot. Shuffle: Are broken down into 6 types Front, back , Side,Double ,leap and Step ;A forward brush followed by a back brush to the front, side or back,executed rapidly in a 16th note rhythm and counted "a 1"
.Front Shuffle:The basic "Shuffle" - with the feet in line with the hips and the toes directly forward, flex the R knee up in front of body -- lower the leg, striking the toe of the foot against the floor in a forward motion. At this point, the L or supporting leg is straight, where in the R ft is straight and extended forward of the body. As you flexthe R knee, strike the toe of the R ft on the floor in a backward motion. The shuffle should be executed slightly forward of supporting foot. The free foot should always remain in front of the supporting leg by flexing the knee forward and up on the back brush.
Side Shuffle:Extend the right foot to the R side, toes are in line and there is no turnout of the R foot.
