Why is PACIFE music different?

In his Harvard Lectures, Bernstein told of ‘Primal Tunes’, those sequences of notes that children around the world, when left to their own devices will chant in their games. PACIFE music was constructed using these tunes, some mathematical characteristics of Bach, (allowing the baby to mentally trace musical patterns) and basic peaceful qualities of music as indicated by the monitors giving it profoundly soothing effects.
