4/27 Today in Weird Music History: 1810. Ludwig van Beethoven pens a short piano piece mistakenly thought to be called Für Elise. In actuality, it is probably Für Therese. Not published until 40 years after Beethoven’s death, it is surmised that the copyist had trouble reading Beethoven’s famously bad handwriting and made an incorrect assumption. Therese Malfatti is widely believed to be the dedicatee of the piece. She was a friend and student of Beethoven’s to whom he proposed in 1810.

The manuscript is considered lost, so we may never know for certain.
