Repetition, redundancy, perseverance.

In a musical score, the colon-like repeat symbols—as shown on the Repeat Card—bracket a passage that is to be played again. There’s usually a notation above the passage indicating how many times it is to be replayed: 2x, 3x, etc. 

Repeat is a Directive card, and directs the querent to try, try again. It might also indicate a rerun, or an endless loop or cycle that needs to be broken out of.
