We've been working with the triad, with the root, 3, and 5, using my playing cards as a way of representing that. Now let's get into some 7th chords, allowing us to work with raise 2. Which are the same as drop 2 chords, so we've got root, 3, 5, & 7. Drop 2 is an arranging term, arrangers use terms like, drop 3 and drop 2, drop 2 and 3. Drop 2 and 4, but a configuration that works particularly well on the guitar, is a drop 2 shape. The easiest way for us as guitarists to look at drop 2 voicings. Is to raise the 2nd degree from the bottom, up an octave. If we take a root position 7th chord, root, 3rd, 5th, 7, C, E, G, B-flat. We take the 3rd and move it up an octave, that's the 2nd note from the bottom that we've moved up. That gives us the configuration of a raise 2. Again, I've taken the 2nd voice from the bottom, and moved it up an octave. This gives us the configuration of a raise 2 voicing, which is the same as drop 2. This represents Major 7, Minor 7, dominant 7th, Minor 7 flat 5. All of these shapes are easily performed with this configuration. Putting the raise 2 concept onto the guitar, I'm going to play a C7. [MUSIC] C, E. [MUSIC] G, B-flat. [MUSIC] Take the second note from the bottom. [MUSIC] That's the E, and move it up an octave. [MUSIC] From E to E. [MUSIC] So instead of root, 3, 5, 7, now we have root. [MUSIC] 5th. [MUSIC] Which is unmoved. 7th. [MUSIC] Which is unmoved, and the new position for the 3rd. [MUSIC] This is a drop 2 shape for a C 7. [MUSIC] If I were to do C Major 7, C, E, G, B. [MUSIC] Again, I take the second note from the bottom leave the others the same. It's the same note, E moves up an octave. [MUSIC] That gives us this shape, C Minor 7, C. [MUSIC] E-flat. [MUSIC] G-flat. [MUSIC] B-flat. [MUSIC] Again, the notes, other than the 2nd from the bottom, stay where they are. This E-flat migrates up an octave. [MUSIC] Giving us this shape for a C Minor 7 flat 5.
