In physics, coherence is a property of waves, that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a wave.
When interfering, two waves can add together to create a larger wave (constructive interference) or subtract from each other to create a smaller wave (destructive interference), depending on their relative phase. Two waves are said to be coherent if they have a constant relative phase.

we are all born with a pineal gland
deaf dumb or mute it will understand
because our bodies skin is the antenna
our pineal the receiver hence whenever
there`s an em signal of harmonic coherent
nature we respond with positive intent
phones tv`s and other mechanical creators
are incoherent makers guiding us to haters
