This is the tuning
C2-G2-D3-A3-D4-G4 tuning (for a children's 53 cm scale length guitar)
Because the highest 3 strings A3-D4-G4 are of equal intervals of 4 apart, it allows for ordinary major and minor chord triads with easy dominant and major 7nths.
Notice that the 4-strings G2-D3-A3-D3 is already an Irish bouzouki tuning
This applies for the Oud and even a66cm scale length standard 6-string guitar
C2-G2-C3-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
It has the minor-major triads at highest pitch
THE LATER TUNING ALLOWS TO PLAY IN MELODIES THE PARTS OF THE MELODIC THEMES OF INTERVALS OF 2 OR 3 HORIZONTALLY WHILE SΗIFT THE MELODIC THEME BY INTERVALS OF 4, 5 OR 8 VERTICALLY (FOR MELODIC THEMES MUTATIONS). IN TOTAL I FIND THIS TUNING VERY CONVENIENT FOR MELODIES IMPROVISATION.
