Book 2 opens with a new My Own Song improvisation on CDEFG. Unit 1 introduces phrasing and legato touch, and also presents harmonic 2nds and 3rds with staccato touch. The following two units are dedicated to the introduction of 4ths and 5ths. Also in Unit 3, sharps are introduced in a diatonic setting starting on D, and flats are introduced as blues notes. Most pieces in the second half of Book 2 coordinate hands playing together. This book works very well for transfer students. The book includes a code that gives you online access to beautifully recorded backing tracks and MIDI files for download or streaming.
