Here goes. First you have to be atleast an intermediate pianist and knows what chords are.

All you have to do is to video yourself doing the tutorial or teaching the lesson. You must use "Youtube" to host the video. There should be an evidence that you're the person in it. Maybe put a paper on your piano with your username in vizzed written on it. Without the paper with your username, your entry won't be accepted. I'll stop accepting entries once we already have at least 3 videos to choose the winner from, or after a month, which ever comes first. If after a month, we still dont have any entry, this contest will remain open until we have 2.

The winner would be the one who made the video that I found the most helpful. Yeah, I'll be the one and only judge since I'm the one who's gonna use the video. I won't sell it or something like that. Just for personal use. You see, I'm more of a pianist who plays with scores or music sheets, and at the moment I lack at the "play by ear" department. I know how to play by ear, just needs to brush up the skill. But I'll still require you to make the video as if the one who's gonna watch it is a total beginner when it comes to playing by ear. Why? So I can fully understand the lesson.

First place gets 8000 Viz. 2nd and 3rd gets 1000 Viz each. If there'll be no 3rd placer, then the second placer gets 2000 Viz.

This sounds kinda silly, as you need perfect pitch to do that. But I would try if I had a YouTube account. =D
