(please dont come here telling me about crotchets and minims cos i know about those stuff.... thanks!)

Answer 1

tapped note? or implied notes?

Answer 2

Hey Barney

That circle represents an open string which makes the tapping sound faster than it actually it.

I use that technique as well as Richard Johnsdon. It gives a different effect to your playing , plus, an extra open strong note.

You play the open string and hammer the note where you plan to begin soloing or tapping. You can do that technique anytime and in any position.
