The Art Of Sound One of music's exquisite pleasures is the great variety of feelings conveyed by the blending of the instruments. The sound of brass combined with strings is unique. It doesn't sound like either of them. Similarly, the exact emotion a chord conveys depends on the balance and inversion of its constituent notes. Music is the art of sound.
Music depends on balance.
Maybe this is the connection between the ear's double function as the organ of hearing and the center of balance. Just as balance is the keystone of sound, similarly to hear G- d in the world we have to balance, to order and to evaluate all the information from our senses. One of the most lethal enemies of balance is pride. The month of Av is related to the element of Fire. Fire, like pride seeks to rule at all costs.
