Make sure you tune your low E string down a whole step to a D. Once you’ve hammered on each string, make sure to keep your fingers down on the fretboard. These are chords, even though we’re hammering on them one at a time. If you venture into the harmonic tapping version, take your time and make sure you can get a nice ringing harmonic by tapping each open string right on the 12th fret. Before trying the hammer ons, practice hitting one string at a time - just the open strings, from 6 to 1. Work to get a clear, bell like ringing. Have fun!
