I was in a singy mood today and lalala-ed to a Tchaikovsky piece called "The Crown of Roses." I didn't sing the lyrics because I don't know the Russian lyrics, and the appropriate English lyrics were written sometime in the last 50 years, which means they may still be under copywrite (there's another set that's not, but I don't like those lyrics).

However, I think of my voice as an instrument, the same way a celloist might think of their cello as an instrument, so to me, lyrics don't matter, just the music. I added some echo-y special effects for fun.
