This set (650 200, orange label) is Pyramid's basic 5-course Arabic tuning set, with plain 3rd course. A good all-around set for Arabic ouds.
This is a 10-string set, it does not include the single 6th bass course. For an 11-string set, add the 6th course (650-206) separately.
For a 12-string high f'f' set, you can add the 0 course (650-001) separately instead.
