Review from Sam: Revolutionary way to learn chord progression!

Already knew circle of 5ths when I first learned theory, but didn't know that it also can be used to chord progression for every key.

Rosa structured the whole course in such a detail where it takes you from a player who can't play without score to a player who can start playing simple songs by ear. But what is more important is that you can advance further from there by playing in different keys, exploring more advanced chords using her concept.

Even if you are an advanced player, I think this course still can help you build a solid foundation in understanding the chord progression in more details.

Highly recommended!


Review from Ángel Candelaria: Very Useful

A great resource for both students and music teachers. HIghly recommended!
