Total Tonalization 240 Tonalization scale exercises covering all twelve keys. Eddie Lewis wrote this book for his students in 2006 for a friendly competition between his students. He called it the Total Tonalization Contest. The student who finished all 240 scale exercises first was to receive one month of lessons free. The contest was a hit and inspired all of his students to practice their scales. Since then, we have made the exercises available to the public in book form. These exercises are unique from typical, traditional scale exercises which only test the students memory and knowledge of the scales. Spending time practicing the Tonalization Studies goes far beyond learning scales. The exercises encourage students to begin thinking in each of the keys. The benefits of practicing the Tonalization Studies include better sight reading, better inprovisation, better intonation, more functional and practical range, better tone and better endurance.
