My daughter painted a Fairy Wren on a piece of calico to make a cover for my keyboard. I had asked her to paint black and white notes on the calico as I was concerned that some one might accidently put a weighty object on the key board not realizing that it was a keyboard.
She also added a lyre. The Australia Lyrebird has tail feathers shaped like a lyre. I think the leaves and nuts represent the Australian Eucalypt. The word eucalypt comes from the Greek which means "well covered" referring to the cap which covers the stamens.
I think my keyboard is well covered. JT.
