By looking at Wikipedia, both Persian and Double harmonic scales seem pretty different.

However, I have a book about scales for guitar where I found this Persian scale which, to me, sounds exactly like the Double harmonic one:

Am I missing something?

They sound nearly exactly the same. There is a slight difference, in that the 5 of the Persian is a ♭5, whereas the 5 in the double hamonic is P5. Playing a melody which didn't have a 5 (quite rare!), it would be impossible to say which scale is being used out of the two.

The one posted has a P5, so can't be the Persian scale. And seems to go awry in its middle. Sometimes, there are inaccuracies on the net - particularly on, it seems, guitar sites...

  • To me the diagram seems correct for double harmonic scale, or do I miss something? Nov 23, 2021 at 16:35
  • @user1079505 - I meant if it's supposed to be Persian, it goes awry.

  • So you agree the diagram from my book is double harmonic and not persian? I'll just write a note next to it in the book Nov 23, 2021 at 16:58

    If it's stated in a book, and it's wrong, at least the publishers have a right to know as well.
