Piano Chord Compass

This Piano Chord Compass pairs a physical sliding chord chart with a 72-page guidebook, helping piano and keyboard learners see how chords are built. Move the slider to the chord you want and view the corresponding keys across a single octave.

The visual format connects major, minor, diminished and augmented chord shapes to the theory behind them. It is a practical set for beginners, developing players, teachers and songwriters who want to work something out clearly before putting both hands back on the keyboard.

Why You'll Love It

• See the keys to play — The sliding device reveals the keyboard notes for the selected chord.
• Compare core chord types — Explore major, minor, diminished and augmented chords, along with seventh chords.
• Connect theory and practice — The tool makes chord structure visible while the book supplies terminology and explanation.
• Support songwriting — Use the set to work out basic piano chords and test harmonic ideas.
• Teach from a shared visual — Students and teachers can inspect the same chord layout away from the keyboard.
• Keep learning portable — The compact, lightweight tool and printed guide fit into a small practice setup.

How to Use It

1. Choose the chord you want to learn or check.
2. Slide the compass to that chord name.
3. Read the highlighted keyboard notes across the displayed octave.
4. Use the 72-page book for explanation, then play the chord on a piano or keyboard and apply it to a song.

What You'll Learn / Explore

Explore how major, minor, diminished, augmented and seventh chords are formed and how their structures appear on the keyboard. The guide contains substantial terminology, so new learners can take it one section at a time and revisit explanations as their playing develops.
