Becoming proficient with five-finger patterns in all keys increases fluency in note reading, technique, theory, and sight reading. By playing pentascales in each major and minor key, students integrate improvisation, transposition, ear training, and other musical skills including composing their own original music. This book proceeds in order of ascending sharps and flats. In each unit, one new key is explored and a previous one reviewed. Features two puzzles, speed drills, and extra pattern practice in the back of the book. Can be useful for all ages --- private or group students.
