You should know this. T_T

Um, music is not far from video, in that the audience has an attention span of about three seconds. In video, Directors avoid showing the same shot for more than 3 seconds or the person will look away. It's basically the same with music, where if you have the same 4 bars of music playing over and over, no matter how beautiful it is, it the listener will stop listening. I'm not sure what the limit is, I'd say repeat no more than 4X.

Try it out, add something in to break the pattern.
