The purpose of this book is two fold. Develop your key retention and improve your aural conprehension of the most common key centers that are created from the modes of Major, Melodic Minor Ascending, Diminished, Whole Tone and Harmonic Minor. There is also a set of 12 tone melodies included. Developing a strong sense of key makes many aspects of ear training easier and becoming familiar with the common key centers helps you compose and improvise with greater clarity. Exercises are presented in all keys and the 4 accompanying CDs allow you to work on these exercises in all keys.

The idea is to slowly wean you away from having to hear a drone as a key reference and have the key center become a natural part of the way you hear. To do this you will work on each set of singing exercises and slowly remove the drone until you can hear a cadence and then sing all the way through any exercise in this book by only getting a key reference to start. There are 4 CDs that accompany this book will help you reach this goal.
