Every musician will come to the point where they have learn how to carry through. They have to continue on, not stop in the middle of the song. If you're playing, and you lose track, always feel comfortable by going to the edge of the drum to get back on track. And then lead back into your spot. It might happen like this....
By keeping my hands going and moving, my body will quickly get track of the tempo, and will allow me to come back in without losing track of where I am.
