My inspiration came to me, via wikipedia, quite quickly, however it didn't turn out quite how I envisioned it.
I am posting this, because it was an interesting experiment, or series of experiments and, isn't that what the challenge is all about? I had fun doing it and didn't let myself stress over the things that didn't quite work. It's a learning experience and this certainly was, for me.
"Water Music" does exist, but the premiere as depicted in the picture is only hearsay, as the painting was painted a hundred years after the supposed day. But supposedly the music was played for King george 1 on a trip up the Thames River on 17 July 1717. This story is what the handwriting in the background tells.
Also, my picture is a bit hard to read, and this, I think is due to the shiny gold affecting the other colours in the picture, like glare.
So that is my piece! As I said, it was quite an experiment.
