Isn't the Ab7 in those chord progressions really one of the German or Italian augmented 6th chords instead of a Neapolitan?? Both can resolve down a half step although the Neapolitan isn't a dominant chord, but rather a simple inverted major chord. The Aug 6th chords are on the other hand. The Ab is also a half step above a dominant, a common home for the Aug6 chord. :confused: [/B]

Ab7 to A7 is not resolving down a half step, but up. What you are suggesting would be Bb7 to A7. Just noticing the mistake.:)
