Guitar Theory - The Perfect 4th - using pinky and ring fingers on adjacent strings

In this listening exercise, we listen to the sound of the Perfect 4th interval, while using the pinky and ring ringers across two strings.

On a standard E tuned guitar, there is a perfect 4th interval, or offset, between all pairs of adjacent strings, except between G-B strings.

So to do this exercise, use your pinky and ring fingers, to fret all possible notes, on all possible strings, on all possible frets...

Between the G and B strings, you will have to adjust your pinky finger UP one fret, to get the Perfect 4th shape and sound.

To train your ear to hear the perfect 4th interval, use the song ‘Here Comes The Bride’

This exercise is important because it gets your pinky and ring fingers exercised, and strong, and working independently, and working together,

And most importantly, it gets these 2 fingers prepared to become HALF of a G chord shape.
