MonoMonday: Sounds

Well this was a tricky theme from Loulou164, for today's MonoMonday challenge: "Sounds: The eye must learn to listen before it looks". Fortunately we still have a guitar in the house, belonging to Son#1, so I thought I'd let my eyes (or the camera anyway) "listen" to the vibrating string. I'm not sure whether this really meets the challenge but it's as close as I could get!
