popMATICS Foundations (The Missing Keys)
popMATICS Foundations (The Missing Keys) is a complimentary resource for those who have purchased The Ultimate popMATICS Pocket Guide. Although formatted a bit differently, they provide all of the same information from the standard notation files included with popMATICS Foundations in C, F & G Major, but for the other nine keys.
The primary benefit of learning to think (and hear) in numbers before letters is that you only have to learn one number system. As you work through the keys, the letters representing each number will change, but the underlying harmonic structure remains. popMATICS approaches learning by listening and reading through writing. Once students have grasped the concepts for one key, they will apply to all. For these reasons, it was an intentional decision to simplify the content for The Ultimate popMATICS Pocket Guide and instead offer the missing keys as a bonus for those who want it.
