The kids can probably tell you the Macarena dance steps but just in case you want to get a bit of practice in, here you go........
On the count of each beat just follow the Macarena dance moves below:
Beat 01: Place R arm straight out in front of you at shoulder height, palm facing down. Beat 02: Place L arm straight out in front of you at shoulder height, palm facing down. Beat 03: Place R arm straight out in front of you at shoulder height, palm facing up. Beat 04: Place L arm straight out in front of you at shoulder height, palm facing up. Beat 05: R hand grasps the inside of L arm at the elbow. Beat 06: L hand grasps the outside of R arm at the elbow. Beat 07: Place R hand behind R back of neck. Beat 08: Place L hand behind L back of neck. Beat 09: Place R hand on L front hip. Beat 10: Place L hand on R front hip. Beat 11: Place R hand on R back buttock. Beat 12: Place L hand on L back buttock. Beat 13: Swing your hips to the left. Beat 14: Swing your hips to the right. Beat 15: Swing your hips to the left. Beat 16: Clap your hands and jump turn 90 degrees to the right.
That's all there is to it!
If you haven't got the Macarena dance music already I recommend that you get the Latin Fiesta CD which not only has the Macarena dance but lots of other great fiesta party songs.
