Today’s Wonder of the Day was inspired by Riley. Riley Wonders, “How Did Tap Dancing Start?” Thanks for WONDERing with us, Riley!

What do you get when you combine fun music, fast feet, and a good sense of rhythm? The clickety-clack and tappity-tap of tap dancing, that's what!

Tap dancing mixes two beautiful arts — dancing and making music — into one mesmerizing act. Tap dancing can be recognized by the unique tapping sounds created by metal plates that are attached to the ball and heel of each dancer's shoes.

When they're tapped against a solid surface, such as a wooden floor, the plates create a signature sound. As tap dancers tap across the floor, they create music while they dance!

Many companies make special tap shoes that have custom tap plates attached to the bottom of the shoes with screws. Since each shoe has a tap plate near the toe and one on the heel, tap shoes are sometimes called "two shoes and four taps." The screws that attach the taps to the shoes can be adjusted to change the sounds they make.

Of course, it's also possible to make your own homemade tap shoes by taping quarters or (with the help of an adult) screwing metal plates to the bottom of any pair of shoes. It's also possible to tap dance in shoes that have a hard, solid sole. However, the sounds such shoes make is not the same as true tap shoes.

Tap dancing has roots in various dances from cultures all over the world. Some likely influencers of tap dancing include African Juba dancing, English clogging, Irish step dancing, Native American stomp dancing, and Spanish flamenco dancing.

Tap dancers often improvise, making up their specific moves and beats as they go along. They also rely heavily on syncopation, which means they use an irregular rhythm to place stresses or accents where they usually wouldn't occur.

Would you believe you can even tap dance without music? Just like singing without music, tap dancing can be done “a cappella."

Instead of dancing to music, tap dancers instead create their own unique rhythms using a variety of special steps.

Tap dancing was popular in America from the 1930s to the 1950s. The best tap dancers of the time moved from touring shows to Broadway to movies and eventually television.

Some of the famous tap dancers from this period were Fred Astaire, Ginger Rogers, Shirley Temple, Gene Kelly, Rita Hayworth, and Bill “Bojangles" Robinson.

With the birth of rock and roll, tap dance declined in popularity. A new form of dance — jazz dance — eventually evolved out of tap dance.

Although they were similar in the past, tap dance and jazz dance are considered separate forms of dance today.

Traditional tap dance is once again starting to become popular. Modern tap dancers include Gregory Hines and Savion Glover.

In fact, Savion Glover recently helped to bring tap dancing back into the mainstream when he choreographed and danced for the movie Happy Feet, which told the story of a tap dancing penguin.
