Book 5 is 95 pages. See photos for examples. Each book in the Let's Start Music Series provides the student with an incredible learning resource from Anita Brandon at Rethink Learning. Books 1-4 include a CD. Anita has taught piano for over 50 years and has found effective ways to communicate the foundations of music theory in both an interesting and logical way. This is not another run-of-the-mill theory book where the author tries to cram ideas into your head with no rhyme or reason. In the Let's Start Music series, Anita capitalizes on a tri-sensory approach that works effectively with all types of learners. If you, or your child or student are just beginning music, you can't go wrong with this series! Also available is a brand new book: Let's Improvise!
