Broadway star Savion Glover (Bring in 'da Noise, Bring in 'da Funk) is among the dance luminaries offering a tap tutorial at Northwestern University beginning next week as part of the Chicago Human Rhythm Project's tenth anniversary celebration. "People hear tap, they think flaming batons and sequins," says Lane Alexander, who founded the program. "Actually, rhythmic dance is an ancient tradition--humans danced before they spoke. Tap, a combination of Irish and African dance, is America's contribution to that tradition." He says this faculty is "unlike any that can be found anywhere, including New York and Los Angeles." Besides Glover, it includes (among others) Bill Irwin, Dianne "Lady Di" Walker, and Danny Daniels. Students can sign up for an intensive "residency," working with one teacher four hours a day for five days, or a "buffet" of one or more 90-minute courses each day with different teachers. Tuition for the "buffet" courses starts at $120; the residency course is $425. Housing and meal plans are also available. It will be held at the Marjorie Ward Marshall Dance Center, 1979 South Campus Dr. on Northwestern's Evanston campus. Classes begin August 7, with a second session starting August 14.
