Haha, I never practiced or anything and didn't care to.
I remember one of the last tests that they made us take, I went after some girl who played like amazingly well. Then he calls me up, tells me to play a specific song.
I looked at him, put the recorder in my mouth, didn't bother to cover a single hole, and just blew as loud and high pitched as I could for 2-3 seconds. Gave a bow, and walked back to my seat.
He then looked down at his desk, wrote on a piece of paper, and sent me to the hall where I spent the rest of that period on a bench reading Goosebumps.
