Keys for the Kingdom is a fully-graded piano series designed especially with the Christian student in mind. Level A begins on the black keys, progresses through un-staffed, relative pitches, introduces the staff one line at a time, and culminates in on-staff, middle C playing. Each lesson provides gradual progress, using familiar songs, hymns, and choruses throughout. All method books have a music dictionary on the last page which corresponds to each level. For comparison, Keys of the Kingdom Level A could easily be studied alongside the first half of Keyboard Treasury, Volume 1.
