Lockstep

This is literally the only game in the Rhythm Heaven series that has been explicitly mentioned to exist 
solely in order to teach you basic rhythm. See this article.
== Cultural Significance ==
Lockstep is one of the most well known games within the Rhythm Heaven community, mostly for its difficulty for newer players. This has led to it gaining cult followings, one of the more significant ones being the "Stepsona" following. The featured characters in this game, the Stepswitchers, however, have not had nearly as much significance within Rhythm Gehenna compared to the absolute chad, Bach.
