With the help of annotation editor in YouTube, you can have some creative idea like this. Kokokaka.com has created this piano game video on YouTube. After the video loaded completely, you can actually play different keys to make the sound. Apparently, when you click on those keys, it will skip to different parts of the video in order to make the sound. Would that be possible we can play a sound with this YouTube video?
