Piano keyboard cards contain a pictured keyboard on the cards with note indicators on keys to be played and fingering numbers showing the finger to be played. These piano keyboard cards have several varieties including scale and chord keyboard cards. These piano keyboard cards can be used on their own without a piano. Also included is a music notation sheet that has all notes of music notation labeled and a fully labeled piano sheet that has all the notes on a piano labeled. Used in conjunction these sheets' line up together clarifying where each key of the piano is on a musical scale. Also included is a fully combined version of the music notation and piano sheets.

A system of teaching piano playing and music theory having piano cards. Piano cards are a flash card system with piano note information on each card. These piano cards are placed above piano keys of a piano or other keyboard designating keys to be played in a specific scale. Black and white triangles on these piano cards designate ebony and ivory keys to be played and can only be placed on a keyboard correctly if aligning white and black triangles with ebony and ivory keys. Triangles designate fingers to be used on fingering cards by way of numbers designating fingers. On music theory cards numbers inside triangles designate scale degrees. On chord cards numbers designate degrees to be played. This music teaching system further comprises a music wheel that has been color coded designating the key a scale is in.

A Chord Map comprises three circular, independently rotatable, concentrically aligned layers of music information: chord array, mode numerals, and grouping. The chord array layer comprises an inner ring (12 major chords), a middle ring (12 minor chords), and an outer ring (12 diminished chords). Text, color, and shape are used to identify the chords, harmonic relationships, and intervallic distances. Spatial organization illustrates chord relationships. The mode numerals layer comprises an inner ring, a middle ring, and an outer ringeach comprising 12 symbols to identify major chords, minor chords, and diminished chords. Sharp and flat symbols further distinguish chords in relation to a given tonic. The mode numerals layer may additionally comprise seven mode labels. The grouping layer comprises an outline to group chords and symbols in the other two layers. The mode numerals layer and grouping layer are transparent so that the information in the chord array layer is visible.
