Yes, that's what it was. Still, it was fun to go thru the excercises to see where you need help. Basically the idea is to stop learning to recognize intervals in isolation, They only make sense relative to the key you're in. So the method is to 1) recognize the tonic/root of the melody being played, 2) recognize the notes being played by "feeling" how it would resolve to the tonic, 4th, or 5th, 3) increase your short term memory by practicing, so you can hold all the notes of a phrase in your head.
No doubt this would work. The package includes practice files.
