The Slap Technique/The Thumb (T)
Hit the thumb against the string close to the fingerboard rapidly and firmly, twisting the wrist then releasing the thumb immediately after contact with the string. This rhythmic attack is characteristic to slap playing and is one of the selection of sounds that create the complete slap.
A long sustained note plays an important role in the outcome of the sound. It is achieved by the accuracy and firmness of the movement not by the force used. Smashing the string will not produce a clear sound and will in fact create unwanted background noise. Control of noise is imperative.
Example 345 uses demonstrates this technique. It is played entirely on the open E string alternating between sustained and muted ghost notes. Once confident with the Example play it on different strings and fretted notes.
Example 346 is a basic Rock feel played with the slap technique.
Example 347 is another basic eighth note thumb slapping groove on the E string.
Example 348 uses hammer-ons and slides to create a variation of the previous groove.
The following sixteenth note grooves employ these technical concepts.
