A set exercises on "ii-V7" and "ii-V7-I" progressions. This volume is great for learning how to "hear" these different progressions. The book is broken down into 4 sections: 1/2-step ascending, whole-step ascending, 1/2-step descending, and whole-step descending. 7 types of "V7" chords are used in this book: #9, b9, #11, #9/#5, #9/b5, b9/#5, and b9/b5 chords. Volume I contains 56 exercises and each exercise uses all 12 key signatures. Volume I is preparatory for Volume II where hymns and praise songs use the chord progressions from this Volume.
