The Salsa Rhythm Machine teaches salsa-dance students how to find the elusive rhythm in salsa music. It plays music while displaying the beat-count, and gives helpful hints about how to find the one-count. The program also has a testing feature that the student can use to see if he or she really can stay on the rhythm. On the Basic Step window, the student can see two feet icons moving to the rhythm, and can follow along. The feet can be set to lead or follow, and break on the one-count or the two-count. By being able to follow along like this, students can learn much more rapidly since they can practice at home in addition to taking classes.
