I have spent a good chunk of my morning attempting to learn "Happy Birthday" on my theremin for all the Aries folks in my life. It's coming along, but it still sounds really whiny and unpredictable, as if Eeyore were huffing helium balloons and singing. To you, Aries. A big earnest offkey birthday croon right in your poor sweet face.
To be fair, my practice schedule is frequently thwarted by the fact that I share the amp of a professional musician who needs it regularly for gigs. And by my lack of structure, hobby-wise.
(Also: my wall doesn't really look that yellow without a blinding digital flash.)
