Mark Greathouse has a master's degree from Stanford University and has composed more than seventy piano compositions, some of which are used in this book. He and his wife, Helena, a former international judge of rhythmic gymnastics for twenty-nine years, have created several CDs and perform music regularly around their home city of Portland, Oregon, and take their music each year to various places in the US and Europe. Mark and Helena Greathouse are a musical duo and live in Portland, Oregon. Mark plays the accordion, and Helena sings and dances. They call themselves Greathouse of Music. Mark's introduction to music began at the age of five when his father, a music teacher in Portland, Oregon, introduced him to the accordion. During his teenage years, Mark won several awards for his accordion performances before going to Europe to study German, where he met his future wife, Helena, from Prague. Mark loves to compose melodies, especially on the piano. It turns out that they lend themselves quite well to dance. This combination of melody and dance has led to writing Dancing for Fun, books 1 and 2. The dances have been professionally choreographed, and Helena's extensive rhythmic gymnastics background has helped immensely in capturing the exact movement in written form.
