This conga class by Michael Pluznick features the Mano Secreto (or secret hand) technique for conga drum playing part 2, which is a "5 over 4" heel tip roll on the left hand that actually plays 5 beats at the same time as the 4 pulse of the mambo rhythm pattern.
Bien Micke, muchas gracias por tu aporte,, estas tocando con un quinto y una conga?
