To the Greeks, the supreme function of music was to "praise the gods and educate the youth". In Egypt... Initiatory music was heard only in Temple rites because it carried the vibratory rhythms of other worlds and of a life beyond the mortal.
PlutarchNature without learning is like a blind man; learning without Nature, like a maimed one; practice without both, incomplete. As in agriculture a good soil is first sought for, then a skilful husbandman, and then good seed; in the same way nature corresponds to the soil, the teacher to the husbandman, precepts and instruction to the seed.
Plutarch
