I highly recommend the film,“Go in Peace, Rain,” about Jewish worship/”geography” in European countries; and how 1 melody recurs in 150 places, as if primal, in major and minor variants. You’ll recognize it: http://www.nationalanthems.info/il.htm (Hatikvah).
Mozart did 14 variations of this melody; the children’s alphabet song and ‘Twinkle, Twinkle Little Star’ echo it, without the minor.


Rain is sacred, around the world.
