Reharmonizing "darn that dream"

Today i'll share with you some work in progress on the beginning of "Darn that dream".I may use it in an arrangement, or even as a starting point for a new tune.

The original chords

My reharmonization with a prolongation of the last measure

The beginning is written with hybrid chords (triads+bass note).They are mostly non-functional chords which evolve into the key of Gb, and then back to the original key with functional chords.

In Gb

Dm7(minor related of subV7/I )

Db9sus(V7sus)

B6/9(IVM)

Bb13(V7/VIm) which goes to its tritone substitute E7,pivot chord that enable us to go back to G. (E7 is subV7/IV in Gb and V7/IIm in G)

I Then wrote another reharmonization of the first four notes:

Once again,the chords are non-functional and written paying attention to voice leading.

You can hear both examples in the audio (the key is changed).
