Train the right hand to read and play melody: from the basic 5-finger C position through skips, accidentals, chromatic runs, and three major scales (C, G, F). Single treble staff with fingering numbers.

Train the left hand through a grand staff: the treble holds a single sustained note while the bass clef grows from single root notes up to full 3-note block chords. Covers all common progressions in the keys of C, G, and F.

Combine both hands on the grand staff: treble melody plus bass clef chords. Bass starts with single root notes (L01–04) and progresses to full block chords (L05–16), finishing with two complete mini-songs.
