My perfect tone

You are my wavelength, clear and bright,
You turn my darkness into light.
You touch it like a soft guitar that echoes near and travels far.
It paints the sky in shades of blue,
A canvas that I'm drawn into.
Your laugh is like a summer storm that keeps my restless heart sober,
And I'm a sailor of your tide,
With nothing left for me to hide.
I used to wander, lost and blind,
