Abstract Thursday Challenge - A Musical Fantasy

I went a bit mad today with the challenge. What started out as an image of a keyboard and some sheet music ended up as a musical extravaganza.
I no doubt wasted no end of time but it was interesting to be dealing with an image that required multiple layers and generally faffing about with imagery. I suppose that is the pint of the thursday abstract challenge in any case, let your creative juices flow, such as they are.
