"Now let me give you the root position voicing for C dominate 7th; I'll go through it more specifically so you know how to actually play it on the instrument. We're going to begin by playing C the base note and the root of the cord of the 8th fret of the 6th string; next we'll add the 5th of the cord which is G, that's on the 10th fret of the 5th string; next we play the E flat note which is the flat 7 of the cord, the minor 7th that's on the 8th fret of the 4th string and finally we add E which is the 3rd of the cord; and E is found on the 9th fret of the 3rd string. So again C the root; G the 5th, B flat the minor 7th and E the 3rd; and we're using the first finger here to bar across 4 strings and we're playing the notes C and B flat with this bar, and the third fingers playing G; the second finger's playing E."
