One of my students gave me a copy of this CD awhile back. I've lost the track listings but the first 12 are all I ever use in my lessons (or personally) and they're all root -5th -root -5th in the 12 keys. I think this CD is a great tool for teaching your ear to play in tune rather that your eye !!!??? It's worth every penny of $20. It taught me things I had heard but never really noticed about how different degrees of the chord or scale are played flatter or sharper (I should rather say higher or lower) Like, FI, a G# functioning as the third of an E chord sounds more in tune when it's played at a lower frequency than when it's functioning as the fifth of a C# chord......
