How to Add Hammer Ons to Bar Chords

"I'm Rick Tobey on behalf of Expert Village and this is Blues Progressions Part 2. Now, we're going to do, add the hammer notes to the bar chords. And in order to do this, rather than play the whole chord, we're pretty much going to concentrate on just the first two strings that we come in contact with, the E string and the A string. The index finger is on the fifth fret of the A string and the third finger is on the seventh fret of the A string. We're going to take our little finger and stretch it and we're going to hit it on the ninth fret of the A string. And you'll notice how we kind of hammered that note on there. Now we can play the D chord with a hammer note simply by taking the exact same position of those two fingers and moving it to the next two strings. Now we can play a B, I mean the E chord by then using the same position starting here on the seventh fret. Index finger on the seventh fret of the A string and the third finger on the ninth fret of the D string. I'm using my little finger all the way up here on the eleventh fret of the D string."
