Watch the Beat Training Explanation online guitar lesson by Kai Eckhardt from Atomic Bass: Time Continuum
Every time signature explored in Time Continuum begins with a trainer. The purpose of the trainer is to give you the most simple bass line possible mapping out three different subdivisions for each meter: 2/4, 2/8, 2/16. After exploring all lines in 2 we move on to 3 starting with the next trainer which now maps out 3/4, 3/8 and 3/16. This system continues all the way to 13. The trainer always precedes every new meter giving you the necessary time to get to know the new shape before diving into the more complex rhythms developed for you in this course.
