This book is divided into a total of 12 major and minor keys, with the minor keys further divided into harmonic and melodic forms. Each key includes parallel scales, scales where parallel and contrary motion intersect, 3rds, 6ths, 10ths, and two-handed octave scales, concluding with chromatic scales. Through various scales, you can not only practice technique but also develop your ability to hear harmonies. I look forward to your musical progress and hope that by practicing this book daily, you'll be able to play more musically with ease. Good luck!
