The first 8 bars of There Will Never Be Another You are built around the movement from the major key to its relative minor. Hearing this as a shift between two connected tonal centers makes the progression as a whole feel more cohesive and gives your solo clear direction.

The bVII7 chord (The Backdoor) plays a key role in the progression, acting as an alternate path back to the tonic. Understanding its function and hearing how it resolves will help you phrase through this section more naturally instead of treating it like a random dominant chord.

The movement from I to II7 is another important part of There Will Never Be Another You, and studying this relationship in a tune like The Girl From Ipanema, where it's so central to the progression, can make it much easier to hear and understand.
