Watch the Blue Note Triplets online guitar lesson by Annie Raines from Blues Harmonica Blueprint
This is a game of catch and release: draw the 4 normally, pull it down into a bend, then release the tension as you slide over to the 3 draw (we’ll also use 2 & 1 draw and 5 & 4 draw). The letting go is the hardest part. Practice it slowly so you can get a good tone on each note before speeding up. Eventually your muscle memory will take over and you will become a fluent, articulate player.
