This is the tuning
Eb2-Bb2-Eb3-G3-D4-A4 (for a children's 53 cm scale length guitar)
It is a 3-courses bouzouki Eb2-Bb2-Eb3 and an interval of major of 3 higher a 3-curses tambouras or sazi G3-D4-A4.
Because the intermediate 3 strings Bb2-Eb3-G3 are of intervals of 4 and 3 apart, it isanopen Eb major it allows for ordinary major and minor chord triads with easy dominant and major 7nths.
For the oud and for a standard 66 cm scale length guitar one tone lower is more appropriate
Db2-Ab2-Db3-F3-C4-G4
The above tuning seems to be one with the almost maximum number of strings an interval of 5 apart which also allows for easy 1 or 2 frets major-minor triads
