The other common use of repetition in photography is to capture the interruption of the flow of a pattern. For example you might photograph hundreds of red M&Ms with one blue one.
Sometimes you’ll find these broken patterns naturally appearing around you and on other occasions you might need to manipulate the situation a little and interrupt a pattern yourself.
Broken repetition might include adding a contrasting object (color, shape, texture) or removing one of the repeating objects.
Pay particular attention to where in your frame to place the break in the pattern. It might be that the rule of thirds comes in to play here (the example to left might be improved simply by placing the red bead slightly higher or lower in the frame).
Also consider your focal point in these shots – the broken pattern might be a logical spot to have everything focussed sharply.
