Part 4/7:
A6 chord: Using a position with the second finger on the fifth fret of the low E, index on the fourth fret of the D, pinky on the sixth fret of the G, and ring on the fifth fret of the B string.
Dominant Seventh: A straightforward shape with the index, middle, and ring fingers on the third fret of the low E, D, and B strings, respectively, with the pinky on the fourth fret of the G string.
D minor 7: Achieved by barring across the fifth fret, with additional fingers on the seventh fret of the D and sixth fret of the B strings.
Dominant 7 flat 5: The most challenging, involving placements on the sixth fret (B-flat and D) with the G string on the seventh fret and the B string on the fifth fret, creating a distinctive half-diminished sound.
