El tambor
A real favorite, perhaps from Venezuela , a gift from a compilation CD from Amalia Francesci.
Your children can probably sing it and show you the motions.
El tambor grande hace .... The big drum goes....
tom! tom! tom! tom! boom, boom....
El tambor chiquito hace .... The little drum goes....
tiqui, tiqui, tiqui, tiqui! tappity tap tapity tap
