Repp has conducted many experiments concerning SMS. So a portion of the review is recalling his own work. SMS is unique to the humans, develops slowly in early childhood and remains almost the same for long years. Although SMS is needed in various human actions, most notably dancing and instrument playing, most of the research uses finger tapping. SMS consists of two error correction phases: phase correction and period correction.
