Music Theory for the 21st-Century Classroom

An additional four-note chord that sounds like and functions similar to a ${\text{V}}^7$ chord is the $\text{IV}$/$\hat{5}$ (or $\text{F}/\text{G}$ in $\text{C}$ major) chord. In popular music this chord often is substituted for the ${\text{V}}^7$ chord

Here is a musical example with the $\text{IV}$/$\hat{5}$ chord in ${\text{A}}^{♭}$ major.

Another example of this chord is found in the opening to the Beatles’ “The Long and Winding Road”. In the key E♭ major, the chord is A♭/B♭.
