Für Elisa McGlynn
"Für Elisa McGlynn" is an arrangement of Beethoven's "Für Elise". I use "arrangement" only in the most technical sense - all I did was change the key from A minor to A major - but for a song as well-known as "Für Elise," changing from minor to major really throws people for a loop.
I did all of this for my college piano proficiency exam. I had memorized the song years before, and wasn't terribly thrilled about having to prove to my professors that I could play the piano, so I got permission from my piano instructor (Lisa McGlynn, for whom the song is named) to do this version of the song as a not very effective political statement.
In case you were curious, I passed.
