This edition is based on the premise that superior musicianship, control of piano technique and pianistic ability result from carefully cultivated aural, visual, kinesthetic and linguistic skills in music. Comprising two levels, Level 1 contains exercises using five-finger patterns and triads in all keys. Level 2 expands five-finger patterns to eight-note scales, adding an octave to the triad to form four-note chords. Seventh chords are also covered.
