I don't know what it is about tapping. So many guitarists still think it is this novel technique, where the act of simply bringing your picking hand to the neck and randomly tapping some note is supposed draw awe from the crowd. I don't believe tapping should be random. I don't believe the decision to play notes on the fretboard with fingers from the picking hand should be like throwing darts.
You've probably been to some concert where a guitarist is playing some already boring solo and then at the very end he plays a handful of randomly tapped notes that don't seem to be in any musical context with the rest of the solo. I don't want you to become a random tapper. Just like with the other techniques that I show you in my guitar lessons, I want you to see meaning in tapping, to see how it can be applied by possessing even a small degree of musical knowledge.
With that said, I am going to show you how to play triad arpeggios using tapping, which will be an important preventative measure to make sure you don't develop random tapping tendencies.
