From Music Hack Day
A switch board with YouTube videos and sheet music to compare several performances of one score.
 About the hack
ClipSwitch lets you follow the score while watching a YouTube video. You can navigate the composition by clicking on the sheet music as well as switch between the different videos that are available for this composition.
This is useful for people like music students and lovers to compare performances, but this should also be useful to compare cover versions.
