" Hi! My name is John Armstrong with expertvillage.com. I'm a professional guitar instructor and today we are going to be studying beginning jazz guitar. Okay next let's discuss the dominant 7 voicing with the root note off the 5th string or the A string. Here once again is the extended D major scale, root 2nd, 3rd, 4th, 5th, 6th, 7th, root 2nd, 3rd, 4th, 5th and 6th. Let's base that off of the D major 7 chord that we had before. Here is D major 7 chord voicing with the root did on the 5th string. Remember if you will in that voicing that we have the root here, the 5th, 7th, 3rd and the 5th again. D, A, C sharp, F sharp and A. Root 5th, 7th, 3rd and 5th. Now by flatting the 7th, by taking the C sharp, the note that I am playing with my middle finger and we bring it back a fret simply lifting off that finger and allowing the index finger which is already borrowing the root and the 5th to also borrow the C note back here. I now have a D dominant 7 and what we can simply refer to as a D7. I flatted my 7. Root 5th, flatted 7, 3rd and 5th. Here it is in D7, B7 so on and so forth. "
