The melody of these songs taken from Persian songs
Are you know Persian song with the same melody?
I'm not sure if any of those songs were originally Iranian/Persian music. It's true that the music from the whole non-Arabic region of the Middle East has a common cadence/theme but it's probably more fluid than we like to think. National ownership of songs has long passed.
It's sure that have Persian songs with the same tune
Here are some of original Persian songs for those melodies:
2- Ghasam by Shahram Solati -
5- Same as 2 (I think it has different gene and lyrics in this melody)
6- Anar Anar by Morteza -
If I could find the other original songs, will post them here too.
