“Ohrwurm” [ˈoːɐ̯ˌvʊʁm] – that’s what the Germans call it. Earworm? Does that exist in English? Here is what I mean: a melody that you hear once and that you can’t get out of your head then. The German composer Ludwig van Beethoven wrote such an “Ohrwurm” – his violin concerto in D major, Op. 61. It’s the only violin concerto he wrote, and one wonders why, since this piece is absolutely amazing! It has a profound effect on me. Whenever I hear it, I feel wide awake, instantly energized, totally present. I also feel transported into another world, floating above life on earth, defying gravity. Unsurprisingly, it is one of my all time favourite violin concertos.
