This cords can determine the pitch of the drum. If the cords and strings are pulled hard, the sound or tone from the drum would increase and if the chords are softly squeezed, the sound will be low. This manipulation can only be perfectly implemented by an experienced drummer. This feature makes this drum different from other traditional drums.
