I taught myself German and I'm at an intermediate level. I'm more comfortable with translating songs from German to English. I'm currently learning Danish.
"When the violin repeats what the piano has just played, it cannot make the same sounds and it can only approximate the same chords. It can, however, make recognisably the same 'music', the same air. But it can do so only when it is as faithful to the self-logic of the violin as it is to the self-logic of the piano." -John Ciardi, 1982
