The DCI World Championship Semifinals on Friday, August 12, 2011, brought together the top 25 corps from the 41-corps preliminaries the day before. Three of those corps were from the Open Class.

Please note that when looking at the scoring recaps, all judges' sheets, including General Effect, are divided in half before being added toward the final score. This is due to the use of two Visual Effect and two Music Effect judges. Keep in mind, however, the Effect averages are not divided in half before being added to the final score, while all the other captions are. Therefore, when it is mentioned that one corps' caption (other than GE) was 0.80 down to another corps' caption score, it really means that spread was worth 0.40 in the final overall score.

View a complete recap of scores from this event.
