This hymn is [coptic]wcperyn[/coptic]:
[coptic]Wcperyn @ ke ecte ectin @ `apo geneac ic genean[/coptic] If you notice the three segments of the hymn are sung in exactly the same tune fitting the vowels onto the music... but as for:
كما كان: هكذا يكون: من جيل إلي جيل
Note that the second segment is musically categorically different and unequal.
So that corrupts the whole meaning of the hymn, which basically is "as it was" is verbally and musically the same as "so it shall be" that is verbally and musically the same as "from generation to generation"...
