Beethoven's 6th Symphony - Pastoral
My 3-year-old son was watching an episode of Baby Looney Tunes that played Beethoven's 6th Symphony in one scene. I was doing something else when my toddler demanded, "Play song!" I asked him, "What song?" He said, "Song on Baby Looney Tunes." I managed to trace the Baby Looney Tunes episode -- "The Magic of Spring" -- to the song he wanted, which turned out to be "Beethoven's 6th Symphony - Pastoral". So I found a recording of it on YouTube and played it, but once wasn't enough. He requested that I play it over and over again and he hummed along to it. Then he would have me play it again, then again, until he fell asleep humming the tune.
