The star of Hawaiian music is the lap steel guitar. The common lap steel tuning is C-E-G-A-C-E, otherwise known as the C6 tuning. We can imitate this tuning by using major 6th chord voicings, glissandos, vibrato bar dips, and artificial harmonics.
Over the bVI to V7, you'll noticed I've add some single melody notes over the Bb I added the 9 and over the A7 I added the b9 and b7. Before going to the G chord, I walked the D6 down a whole step. This is an easy way to turn the chord into a dom9 chord. I do the same thing over the A7 using inversions of the 6th chords. The artificial harmonics added to the II and bII chord are achieved by placing your index finger above the fret an octave higher, holding the pick with the second finger and thumb and picking the string. Lift your finger immediately after picking the string so you don't choke the note.
