tone is part of content. similar to that our non-physical energies along with our physical part makeup our each content.
tone is vibration. to become 'tone deaf' is to literally turn off the perceptual sensitivities that we are developing under the great Masters.
we are learning that we are each a completely whole being/if in our thinking we don't limitedly define ourself as just the earthly person. our each spirit is really quite infinite, quite vast, and the lands of 'emptiness' and 'spaciousness' do lie within it
the word 'style' might possibly be a possible choice for 'tone'. maybe?
