People say making walking bass lines is easy but everytime I encounter movements of 2nd and 3rd (which means also 7th and 6th.. which means anything other than the classic down-a-fifth/up-a-forth movement..) I feel fear.
What is the most common way of treating this kind of passage?
To make the discussion easier, let's take All The Things You Are:

Movement of 2nd:
check out bar 23 ~ 24 (Emaj7 C7+)
Can this work?? | E D# D Db | C ...
Movement of 3rd:
check out bar 27 ~ 29 (Cm7 Bdim Bbm7)
My idea is: | C Eb G Bb | B Ab F D | Bb ...
Thanks for sharing your wisdom
