Piano is the main lesson book in the Bastien Piano Basics course. The carefully graded, logical learning sequence assures steady, continual progress. Original music by the Bastiens includes a stimulating mixture of pop, folk, classical, and contemporary styles. Full-color illustrations throughout entertain and reinforce musical concepts along the way. The gradual multi-key approach takes students through all 12 keys — 3 in each of Levels 1, 2, 3, and 4. Each page is carefully correlated page-by-page with Theory, Performance,andTechnic. All in all, a dynamic way to introduce students to the marvelous world of music! Level 2 presents binary and ternary form, one-octave scales with tetrachords identified, intervals of 6th and 7th, primary chords, triads and inversions, 6/8 time, and the keys of D, A, and E.
