Craig Blake's method is a must-have for the practicing and professional musician. The Equalizer - A Musical Method is a natural and gravitational approach to song-writing by means of numbers and a balance-beam. Simply, create chord progressions with the balance-beam charts, then apply the compatible scales/scale-sets. The Equalizer - A Musical Method can be incorporated by novice, intermediate, and advanced musicians, and it can also be applied to any genre of music such as rock, blues, jazz, country etc., by incorporating the balance beam - it opened up a-whole-new-world of possibilities. My mission: Strive to design a system for music-writing that would ultimately assist the composer during the development process.
