Is A- Db - E the neopolitan chord for the Ab major?
Okay. What's a neopolitan chord?
It's a misspelling of a Neapolitan chord.
As for a Neapolitan chord, you got me-- this was the first time I'd ever heard the term! And after reading about it on Wikipedia and MusicTheory.net I still don't understand it!
According to this page, "a Bbb major chord is the Neapolitan of Ab Major," or "Bbb-Db-Fb." I guess they use the Bbb and Fb notations in case they aren't the same as A and E in the particular tuning system being used.
Seems like it's a major chord built on the lowered 2nd note of the scale.
So in Cmajor, the neapolitan is Dd F Ab. The examples give are first inversion because, apparently, that's a common usage.
There's talk of it being used as a substitute for IV or II before a perfect cadence.
I don't know...Sounds balls to me.
Is A- Db - E the neopolitan chord for the Ab major?
Irrespective of its derivation, it seems that a neapolitan chord (which I had never head of) is, in the end, a normal major chord a semitone above the tonic. So, in your example, the neapolitan chord for Cmajor is Db major.
What is the difference between A & Bbb also between E & Fb ? If there are no differences so your answer agrees with mine.
Mega thanks Sir. You have answered my question.
