Keys for the Kingdom is a fully-graded piano series designed especially with the Christian student in mind. Level B reviews Level A, introduces intervals in C position, begins to play hands together, works with eighth notes, accidentals, and repeats, and culminates in two-hand playing. Each lesson provides gradual progress, using familiar songs, hymns, and choruses used throughout. All method books have a music dictionary on the last page which corresponds to each level. For comparison, Keys for the Kingdom Level B could easily be studied alongside the second half of Keyboard Treasury, Volume 1, and much of Hymns of the Faith for the Beginner Pianist. The 18 Progressive Hymn tunes could also begin to be explored at this level.
