I will admit it. I am not instrumentally talented. Not that I feel ashamed or have a problem admitting it. I have my own talents in the visual field. But as far keeping more than a basic rhythm... I'm at a loss. Remembering all those different notes and exact sounds? That's more buttons to push than it takes to execute a perfect pirouette ;)
But seriously, I would learn to play a string instrument JUST so I could do this song and this song. And I would learn to play the piano JUST so I could do this song, this song, and this song.
What would you like to learn to do? Who knows, maybe I will pursue such things some day, and maybe you will too!
If ever I DO get to do a musical freestyle, expect to see some of those pieces in there, if it would suit The Pony ;)
