Double thumbing is a special form of slapping .

In the normal way that the slap technique is used on the electric bass , the thumb is struck almost parallel to the string from a movement of the wrist. It either performs an up and down movement at a 90 ° angle to the string or it touches the string in a downward movement past it and is then pulled up again (the tone changes considerably as a result).

The double thumbing is similar to the second variant. The thumb does not go past the string, but "punches" it like a pick would. The thumb then lands on the lower string and can now again strike the string that has just been played by pulling it up again like a pick. In the same upward movement, other strings can be torn - similar to the conventional slap technique, but horizontally.

This makes the slap technique much more economical. Bassists such as Alain Caron , Victor Wooten and Marcus Miller made them known to a wide audience in this form. The advantage of this technique is that scales or other licks can be played many times more efficiently.
